[Music] is a MicroBot microbots what is a micro
is a MicroBot microbots what is a micro
is a MicroBot microbots what is a micro bot more typically what is a micro robot
bot more typically what is a micro robot
bot more typically what is a micro robot most people just know it from what
most people just know it from what
most people just know it from what they’ve seen in the movies well the
they’ve seen in the movies well the
they’ve seen in the movies well the first thing you need to know about a
first thing you need to know about a
first thing you need to know about a micro robot is it’s very small so we say
micro robot is it’s very small so we say
micro robot is it’s very small so we say its submillimetre dimensions so for
its submillimetre dimensions so for
its submillimetre dimensions so for reference a human hair is about 100
reference a human hair is about 100
reference a human hair is about 100 microns in diameter so the robots we’re
microns in diameter so the robots we’re
microns in diameter so the robots we’re talking about here are very small so
talking about here are very small so
talking about here are very small so about 8 human hair is wide but about 7
about 8 human hair is wide but about 7
about 8 human hair is wide but about 7 human hair is tall next thing we need to
human hair is tall next thing we need to
human hair is tall next thing we need to know about these micro robots as we want
know about these micro robots as we want
know about these micro robots as we want them to be mobile to move around in the
them to be mobile to move around in the
them to be mobile to move around in the work space they want to be able to
work space they want to be able to
work space they want to be able to control them wirelessly which is a
control them wirelessly which is a
control them wirelessly which is a challenge so if you think about a
challenge so if you think about a
challenge so if you think about a large-scale robot right you can put a
large-scale robot right you can put a
large-scale robot right you can put a battery in this robot powered up and it
battery in this robot powered up and it
battery in this robot powered up and it goes on its way but what happens if the
goes on its way but what happens if the
goes on its way but what happens if the robot is really small right so you have
robot is really small right so you have
robot is really small right so you have a tiny little robot you can’t stick a
a tiny little robot you can’t stick a
a tiny little robot you can’t stick a battery on this robot it’s not going to
battery on this robot it’s not going to
battery on this robot it’s not going to work so what are we going to do well one
work so what are we going to do well one
work so what are we going to do well one thing we can think about doing is maybe
thing we can think about doing is maybe
thing we can think about doing is maybe we can give this robot a little hat it
we can give this robot a little hat it
we can give this robot a little hat it can make it magnetic and so if we stick
can make it magnetic and so if we stick
can make it magnetic and so if we stick a magnet in its workspace it’s going to
a magnet in its workspace it’s going to
a magnet in its workspace it’s going to be attracted to that magnet so it’s kind
be attracted to that magnet so it’s kind
be attracted to that magnet so it’s kind of the approach that we take here except
of the approach that we take here except
of the approach that we take here except we use special mat gets called
we use special mat gets called
we use special mat gets called electromagnets so we can turn these on
electromagnets so we can turn these on
electromagnets so we can turn these on and off whenever we want to and so we
and off whenever we want to and so we
and off whenever we want to and so we can surround the workspace of the robot
can surround the workspace of the robot
can surround the workspace of the robot with these electromagnets and control it
with these electromagnets and control it
with these electromagnets and control it to move in the plane so one of the neat
to move in the plane so one of the neat
to move in the plane so one of the neat applications for these micro robots is
applications for these micro robots is
applications for these micro robots is in the body the body has lots of sticky
in the body the body has lots of sticky
in the body the body has lots of sticky rough surfaces in it so if you wanted to
rough surfaces in it so if you wanted to
rough surfaces in it so if you wanted to just you know pull our robot with their
just you know pull our robot with their
just you know pull our robot with their electromagnet it’s going to get stuck in
electromagnet it’s going to get stuck in
electromagnet it’s going to get stuck in that and that tissue so what can we do
that and that tissue so what can we do
that and that tissue so what can we do well if you think about a car we want to
well if you think about a car we want to
well if you think about a car we want to take the car off rodent it’s rough
take the car off rodent it’s rough
take the car off rodent it’s rough terrain we stick big bulky tires on it
terrain we stick big bulky tires on it
terrain we stick big bulky tires on it can negotiate that rough terrain so
can negotiate that rough terrain so
can negotiate that rough terrain so being fed do the same thing with our
being fed do the same thing with our
being fed do the same thing with our robots so now we can give this robot
robots so now we can give this robot
robots so now we can give this robot some magnetic feet a little bit mattock
some magnetic feet a little bit mattock
some magnetic feet a little bit mattock different magnetic properties than the
different magnetic properties than the
different magnetic properties than the ones on its hat and we can add some
ones on its hat and we can add some
ones on its hat and we can add some other electromagnets on the work space
other electromagnets on the work space
other electromagnets on the work space and we can turn these on and off now
and we can turn these on and off now
and we can turn these on and off now that the robot will now roll and tumble
that the robot will now roll and tumble
that the robot will now roll and tumble like now and go over this rough terrain
like now and go over this rough terrain
like now and go over this rough terrain just like an all-terrain tire once it
just like an all-terrain tire once it
just like an all-terrain tire once it gets to our target location and we can
gets to our target location and we can
gets to our target location and we can then use it to inject some medicine to
then use it to inject some medicine to
then use it to inject some medicine to that target location so that’s the idea
that target location so that’s the idea
that target location so that’s the idea be assigned this microscope tumbling by
be assigned this microscope tumbling by
be assigned this microscope tumbling by a robot that we’ve developed
a robot that we’ve developed
a robot that we’ve developed so it’s about three human hairs wide by
so it’s about three human hairs wide by
so it’s about three human hairs wide by four human hairs long and it looks like
four human hairs long and it looks like
four human hairs long and it looks like a dumbbell need to bail is a magnetic
a dumbbell need to bail is a magnetic
a dumbbell need to bail is a magnetic body buts your oppositely pulled so in
body buts your oppositely pulled so in
body buts your oppositely pulled so in one side the North Pole’s on the bottom
one side the North Pole’s on the bottom
one side the North Pole’s on the bottom the other side the North Pole’s on the
the other side the North Pole’s on the
the other side the North Pole’s on the top it has two modes of operation so for
top it has two modes of operation so for
top it has two modes of operation so for this tumbling mode what we can do is we
this tumbling mode what we can do is we
this tumbling mode what we can do is we can turn your electromagnet on from the
can turn your electromagnet on from the
can turn your electromagnet on from the bottom and it’s going to call the robot
bottom and it’s going to call the robot
bottom and it’s going to call the robot to stand up we can turn that field off
to stand up we can turn that field off
to stand up we can turn that field off and put on a somatic field from the side
and put on a somatic field from the side
and put on a somatic field from the side and call the to tilt over then we remove
and call the to tilt over then we remove
and call the to tilt over then we remove that field it’s back on the ground so
that field it’s back on the ground so
that field it’s back on the ground so now we can cycle this you can get the
now we can cycle this you can get the
now we can cycle this you can get the robot to roll and tumble to the target
robot to roll and tumble to the target
robot to roll and tumble to the target location I also have the second mode of
location I also have the second mode of
location I also have the second mode of operation which is called a sliding mode
operation which is called a sliding mode
operation which is called a sliding mode operation so in this case once we get to
operation so in this case once we get to
operation so in this case once we get to our target location we might have
our target location we might have
our target location we might have manipulate something there so how this
manipulate something there so how this
manipulate something there so how this works is we again put a Matic field on
works is we again put a Matic field on
works is we again put a Matic field on the bottom to stand it up then we can
the bottom to stand it up then we can
the bottom to stand it up then we can tilt it to the side rather than letting
tilt it to the side rather than letting
tilt it to the side rather than letting it fall back to the ground again we can
it fall back to the ground again we can
it fall back to the ground again we can stand it back up again and we can do
stand it back up again and we can do
stand it back up again and we can do this little stick slip motion and then
this little stick slip motion and then
this little stick slip motion and then get the robot to kind of walk along the
get the robot to kind of walk along the
get the robot to kind of walk along the surface and so here’s a video of the
surface and so here’s a video of the
surface and so here’s a video of the robots that we fabricated in the lab
robots that we fabricated in the lab
robots that we fabricated in the lab here at Purdue now so again they’re
here at Purdue now so again they’re
here at Purdue now so again they’re about three human hairs wide by four
about three human hairs wide by four
about three human hairs wide by four human hairs long and here we’re manually
human hairs long and here we’re manually
human hairs long and here we’re manually controlling these electrode Mattox turn
controlling these electrode Mattox turn
controlling these electrode Mattox turn turning them on and off to get the robot
turning them on and off to get the robot
turning them on and off to get the robot to tumble along the surface so first was
to tumble along the surface so first was
to tumble along the surface so first was on a silicon wafer here we’re showing it
on a silicon wafer here we’re showing it
on a silicon wafer here we’re showing it on some biological tissue so you get a
on some biological tissue so you get a
on some biological tissue so you get a sticky surface what you couldn’t just
sticky surface what you couldn’t just
sticky surface what you couldn’t just pull this robot across it without having
pull this robot across it without having
pull this robot across it without having this tumbling locomotion here it’s going
this tumbling locomotion here it’s going
this tumbling locomotion here it’s going on top of a penny so now these features
on top of a penny so now these features
on top of a penny so now these features of the penny are on the same size of the
of the penny are on the same size of the
of the penny are on the same size of the robot itself it’s able to negotiate that
robot itself it’s able to negotiate that
robot itself it’s able to negotiate that surface quite well so then once we get
surface quite well so then once we get
surface quite well so then once we get to our target location we want may want
to our target location we want may want
to our target location we want may want to do manipulation there so here’s the
to do manipulation there so here’s the
to do manipulation there so here’s the slotting mode operation so the robot is
slotting mode operation so the robot is
slotting mode operation so the robot is kind of walking across the surface and
kind of walking across the surface and
kind of walking across the surface and here you can see it you know pushing a
here you can see it you know pushing a
here you can see it you know pushing a small little component in this testbed
small little component in this testbed
small little component in this testbed we’ve also had these robots go over
we’ve also had these robots go over
we’ve also had these robots go over different bumps
different bumps
different bumps so here’s traversing different bumps on
so here’s traversing different bumps on
so here’s traversing different bumps on in the work space so it’s able to
in the work space so it’s able to
in the work space so it’s able to negotiate that quite well we also have
negotiate that quite well we also have
negotiate that quite well we also have these robots going up and down inclined
these robots going up and down inclined
these robots going up and down inclined planes so we can go up and down these
planes so we can go up and down these
planes so we can go up and down these slopes we’re also looking at alternate
slopes we’re also looking at alternate
slopes we’re also looking at alternate evacuation techniques
evacuation techniques
evacuation techniques it’s rather than tumbling the robot
it’s rather than tumbling the robot
it’s rather than tumbling the robot end-over-end can we tumble it the other
end-over-end can we tumble it the other
end-over-end can we tumble it the other way to get even some even more neat
way to get even some even more neat
way to get even some even more neat applications and mobility so this is
applications and mobility so this is
applications and mobility so this is application for these robots is inside
application for these robots is inside
application for these robots is inside the body but there are other biological
the body but there are other biological
the body but there are other biological applications
applications
applications for these robots what you’re outside the
for these robots what you’re outside the
for these robots what you’re outside the body and done it in Petri dishes so when
body and done it in Petri dishes so when
body and done it in Petri dishes so when biologists use a petri dish the grill
biologists use a petri dish the grill
biologists use a petri dish the grill typically grow cells and they’re all
typically grow cells and they’re all
typically grow cells and they’re all congregated into one area so they would
congregated into one area so they would
congregated into one area so they would like to take one of these cells move it
like to take one of these cells move it
like to take one of these cells move it out from that group perform an
out from that group perform an
out from that group perform an experiment on it or they would like to
experiment on it or they would like to
experiment on it or they would like to arrange these cells into a certain
arrange these cells into a certain
arrange these cells into a certain configuration for the Grillet scalpel
configuration for the Grillet scalpel
configuration for the Grillet scalpel there are some other tissue engineering
there are some other tissue engineering
there are some other tissue engineering applications so when they do this they
applications so when they do this they
applications so when they do this they typically use a probe and it will move
typically use a probe and it will move
typically use a probe and it will move the use of probe and actuate it to push
the use of probe and actuate it to push
the use of probe and actuate it to push the cell to where it needs to be into it
the cell to where it needs to be into it
the cell to where it needs to be into it and to arrange it in some certain matter
and to arrange it in some certain matter
and to arrange it in some certain matter one of the problems with this is that
one of the problems with this is that
one of the problems with this is that when the user does this they have no
when the user does this they have no
when the user does this they have no idea how much force they’re actually
idea how much force they’re actually
idea how much force they’re actually pushing the cell with so if you can it
pushing the cell with so if you can it
pushing the cell with so if you can it they don’t know how much force they’re
they don’t know how much force they’re
they don’t know how much force they’re applying to the cell you can damage the
applying to the cell you can damage the
applying to the cell you can damage the cell so we’d like to be able to come
cell so we’d like to be able to come
cell so we’d like to be able to come with the micro robot to help with these
with the micro robot to help with these
with the micro robot to help with these kinds of applications also if you look
kinds of applications also if you look
kinds of applications also if you look at it at a single cell by itself it’s a
at it at a single cell by itself it’s a
at it at a single cell by itself it’s a pretty neat structure it has a nucleus
pretty neat structure it has a nucleus
pretty neat structure it has a nucleus in the middle of the cell and it has a
in the middle of the cell and it has a
in the middle of the cell and it has a skeleton which is called the
skeleton which is called the
skeleton which is called the cytoskeleton on the inside and so if you
cytoskeleton on the inside and so if you
cytoskeleton on the inside and so if you push them on this cell with it with a
push them on this cell with it with a
push them on this cell with it with a probe and exerts a small force to cell
probe and exerts a small force to cell
probe and exerts a small force to cell skeleton will actually reconfigure
skeleton will actually reconfigure
skeleton will actually reconfigure itself to be stiffer where that force
itself to be stiffer where that force
itself to be stiffer where that force was applied and so this is interesting
was applied and so this is interesting
was applied and so this is interesting and so the study of these forces and how
and so the study of these forces and how
and so the study of these forces and how the cell reacts to it and develops is
the cell reacts to it and develops is
the cell reacts to it and develops is called mechanobiology is a very popular
called mechanobiology is a very popular
called mechanobiology is a very popular field and so people interested in trying
field and so people interested in trying
field and so people interested in trying to study this behavior so again we come
to study this behavior so again we come
to study this behavior so again we come with a micro robot can help these
with a micro robot can help these
with a micro robot can help these applications that would be great finally
applications that would be great finally
applications that would be great finally if you look at two different cells they
if you look at two different cells they
if you look at two different cells they say L cell a and insell B and you apply
say L cell a and insell B and you apply
say L cell a and insell B and you apply the same force to these cells they may
the same force to these cells they may
the same force to these cells they may deform or deflect in different amounts
deform or deflect in different amounts
deform or deflect in different amounts and this force displacement relationship
and this force displacement relationship
and this force displacement relationship for the cells is called its stiffness
for the cells is called its stiffness
for the cells is called its stiffness and so if we can have a robot to help us
and so if we can have a robot to help us
and so if we can have a robot to help us apply these small forces we can record
apply these small forces we can record
apply these small forces we can record the stiffness of the cells that help to
the stiffness of the cells that help to
the stiffness of the cells that help to characterize them so a normal cell will
characterize them so a normal cell will
characterize them so a normal cell will have a different stiffness property than
have a different stiffness property than
have a different stiffness property than say a cancer cell and so which how can
say a cancer cell and so which how can
say a cancer cell and so which how can we come with the market robot to help
we come with the market robot to help
we come with the market robot to help with these in vitro or inside a petri
with these in vitro or inside a petri
with these in vitro or inside a petri dish applications well what we can do is
dish applications well what we can do is
dish applications well what we can do is we can add our take our magnetic micro
we can add our take our magnetic micro
we can add our take our magnetic micro robot so if we have a magnetic body we
robot so if we have a magnetic body we
robot so if we have a magnetic body we control the position of it in the petri
control the position of it in the petri
control the position of it in the petri dish by turning electromagnets on and
dish by turning electromagnets on and
dish by turning electromagnets on and off but now we need to be able to apply
off but now we need to be able to apply
off but now we need to be able to apply small forces and record those forces so
small forces and record those forces so
small forces and record those forces so how we’re going to do that so we use
how we’re going to do that so we use
how we’re going to do that so we use something called a vision based micro
something called a vision based micro
something called a vision based micro force sensor
force sensor
force sensor so what this is it’s a soft compliance
so what this is it’s a soft compliance
so what this is it’s a soft compliance structure and we know the stiffest of
structure and we know the stiffest of
structure and we know the stiffest of this devices so as it pushes on an
this devices so as it pushes on an
this devices so as it pushes on an object is going to deform we can now
object is going to deform we can now
object is going to deform we can now observe that deformation with the
observe that deformation with the
observe that deformation with the microscope with a camera attached from a
microscope with a camera attached from a
microscope with a camera attached from a microscope if we know the deformation
microscope if we know the deformation
microscope if we know the deformation and we know the stiffness then we can
and we know the stiffness then we can
and we know the stiffness then we can back out what the force is going to be
back out what the force is going to be
back out what the force is going to be so here’s an example some one of these
so here’s an example some one of these
so here’s an example some one of these robots called the Micro for sensing
robots called the Micro for sensing
robots called the Micro for sensing mobile micro robot it’s about 700
mobile micro robot it’s about 700
mobile micro robot it’s about 700 microns footprint so seven human hairs
microns footprint so seven human hairs
microns footprint so seven human hairs wide seven human hairs long on the back
wide seven human hairs long on the back
wide seven human hairs long on the back end of it you can see a little magnetic
end of it you can see a little magnetic
end of it you can see a little magnetic body which we’re then using with our
body which we’re then using with our
body which we’re then using with our electromagnets to control its position
electromagnets to control its position
electromagnets to control its position orientation in the workspace the end
orientation in the workspace the end
orientation in the workspace the end effector that little spring structure is
effector that little spring structure is
effector that little spring structure is that soft compliant end effector and you
that soft compliant end effector and you
that soft compliant end effector and you see how we’re pushing on this
see how we’re pushing on this
see how we’re pushing on this microsphere our cell is deforming and we
microsphere our cell is deforming and we
microsphere our cell is deforming and we track that and we can then figure out
track that and we can then figure out
track that and we can then figure out how much force we’re using so now we can
how much force we’re using so now we can
how much force we’re using so now we can make sure we play in those cells very
make sure we play in those cells very
make sure we play in those cells very safely they also can get this robot to
safely they also can get this robot to
safely they also can get this robot to move autonomously so we can plan a path
move autonomously so we can plan a path
move autonomously so we can plan a path around obstacles in the workspace so it
around obstacles in the workspace so it
around obstacles in the workspace so it basically gives itself little GPS
basically gives itself little GPS
basically gives itself little GPS coordinates then the robot then can
coordinates then the robot then can
coordinates then the robot then can follow these GPS coordinates
follow these GPS coordinates
follow these GPS coordinates autonomously and then get to the cell
autonomously and then get to the cell
autonomously and then get to the cell and then push it to its target location
and then push it to its target location
and then push it to its target location and this works there’s quite well in
and this works there’s quite well in
and this works there’s quite well in this case and here we’re controlling
this case and here we’re controlling
this case and here we’re controlling just one robot at a time so but really
just one robot at a time so but really
just one robot at a time so but really cool we control teams and swarms of
cool we control teams and swarms of
cool we control teams and swarms of these robots inside they feature just to
these robots inside they feature just to
these robots inside they feature just to have multiple of these robots working
have multiple of these robots working
have multiple of these robots working independently all at the same time so
independently all at the same time so
independently all at the same time so how can we do that well if we go back to
how can we do that well if we go back to
how can we do that well if we go back to our example with our electromagnets in
our example with our electromagnets in
our example with our electromagnets in our in our robots if we have it say a
our in our robots if we have it say a
our in our robots if we have it say a team of three robots and we switch these
team of three robots and we switch these
team of three robots and we switch these electromagnets on all these robots are
electromagnets on all these robots are
electromagnets on all these robots are getting the same global fields and so
getting the same global fields and so
getting the same global fields and so they’re all going to do the same thing
they’re all going to do the same thing
they’re all going to do the same thing so the question is how do you get
so the question is how do you get
so the question is how do you get independent control of these robots if
independent control of these robots if
independent control of these robots if they’re all magnetic but what these
they’re all magnetic but what these
they’re all magnetic but what these electromagnets are are actually just
electromagnets are are actually just
electromagnets are are actually just coils with current running through them
coils with current running through them
coils with current running through them so if we can take these coils and we can
so if we can take these coils and we can
so if we can take these coils and we can shrink them down to the same size of the
shrink them down to the same size of the
shrink them down to the same size of the robots roughly and we can kind of turn
robots roughly and we can kind of turn
robots roughly and we can kind of turn them on their end right we can then
them on their end right we can then
them on their end right we can then arrange them on the bottom of a petri
arrange them on the bottom of a petri
arrange them on the bottom of a petri dish in a big array and then depending
dish in a big array and then depending
dish in a big array and then depending on the direction of the current how it
on the direction of the current how it
on the direction of the current how it flows through these coils we can get an
flows through these coils we can get an
flows through these coils we can get an attractive force on the robot or a
attractive force on the robot or a
attractive force on the robot or a postive force on the robot and then by
postive force on the robot and then by
postive force on the robot and then by planning that and in turn and an
planning that and in turn and an
planning that and in turn and an attorney these on and off at the right
attorney these on and off at the right
attorney these on and off at the right time we can then get
time we can then get
time we can then get independent motion of these teams of
independent motion of these teams of
independent motion of these teams of microrobots in that network space so
microrobots in that network space so
microrobots in that network space so we’ve simulated this this idea and here
we’ve simulated this this idea and here
we’ve simulated this this idea and here you can see three robots being
you can see three robots being
you can see three robots being controlled by these a planar array of
controlled by these a planar array of
controlled by these a planar array of micro coils and we’re able to
micro coils and we’re able to
micro coils and we’re able to independent control these robots we can
independent control these robots we can
independent control these robots we can also use them for collaborative
also use them for collaborative
also use them for collaborative manipulation so travelling informations
manipulation so travelling informations
manipulation so travelling informations to move different objects around in the
to move different objects around in the
to move different objects around in the workspace so we’ve prototyped a system
workspace so we’ve prototyped a system
workspace so we’ve prototyped a system like this at the millimeter scale well
like this at the millimeter scale well
like this at the millimeter scale well we have these coils which are about four
we have these coils which are about four
we have these coils which are about four millimeters by four millimeters in size
millimeters by four millimeters in size
millimeters by four millimeters in size and our robots are two millimeters in
and our robots are two millimeters in
and our robots are two millimeters in diameter and we are actually able to get
diameter and we are actually able to get
diameter and we are actually able to get these robots to move independently in
these robots to move independently in
these robots to move independently in this workspace using this technique so
this workspace using this technique so
this workspace using this technique so we know this idea is going to work our
we know this idea is going to work our
we know this idea is going to work our true goal then is actually to move this
true goal then is actually to move this
true goal then is actually to move this not from the millimeter scale and not at
not from the millimeter scale and not at
not from the millimeter scale and not at the movements but actually use it at the
the movements but actually use it at the
the movements but actually use it at the micro scale so how do we do that well
micro scale so how do we do that well
micro scale so how do we do that well it’s possible to make these these micro
it’s possible to make these these micro
it’s possible to make these these micro coils or you know along the same size of
coils or you know along the same size of
coils or you know along the same size of the robot about 300 microns in diameter
the robot about 300 microns in diameter
the robot about 300 microns in diameter it’s very hard to do it’s very expensive
it’s very hard to do it’s very expensive
it’s very hard to do it’s very expensive so what can we do that’s a little bit
so what can we do that’s a little bit
so what can we do that’s a little bit cheaper needs and easier to make so if
cheaper needs and easier to make so if
cheaper needs and easier to make so if we want to use some standard printed
we want to use some standard printed
we want to use some standard printed circuit board technology instead of
circuit board technology instead of
circuit board technology instead of using micro coils we can actually use
using micro coils we can actually use
using micro coils we can actually use micro strips of wire and we can arrange
micro strips of wire and we can arrange
micro strips of wire and we can arrange them in two layers and it works the same
them in two layers and it works the same
them in two layers and it works the same way so now if we have current going in
way so now if we have current going in
way so now if we have current going in one direction through one of these
one direction through one of these
one direction through one of these vertical coils and give us a force to
vertical coils and give us a force to
vertical coils and give us a force to the right on the robot if we change the
the right on the robot if we change the
the right on the robot if we change the direction of current then it will give
direction of current then it will give
direction of current then it will give us a force to the left and if we use
us a force to the left and if we use
us a force to the left and if we use some of the horizontally mounted coils
some of the horizontally mounted coils
some of the horizontally mounted coils and micro strips of wire we can now get
and micro strips of wire we can now get
and micro strips of wire we can now get forces going up and forces going down
forces going up and forces going down
forces going up and forces going down depending on the direction of the
depending on the direction of the
depending on the direction of the current and so by doing this we can now
current and so by doing this we can now
current and so by doing this we can now if we put two micro robots in the
if we put two micro robots in the
if we put two micro robots in the workspace we can independently control
workspace we can independently control
workspace we can independently control their positions in the workspace at the
their positions in the workspace at the
their positions in the workspace at the same time and someone that need
same time and someone that need
same time and someone that need applications here is for advanced
applications here is for advanced
applications here is for advanced manufacturing if you can then use these
manufacturing if you can then use these
manufacturing if you can then use these robots to assemble very small components
robots to assemble very small components
robots to assemble very small components to commit really interesting devices so
to commit really interesting devices so
to commit really interesting devices so we’re working on some new 3d printing
we’re working on some new 3d printing
we’re working on some new 3d printing technology to make essentially micro
technology to make essentially micro
technology to make essentially micro scale legos and if we can you think of
scale legos and if we can you think of
scale legos and if we can you think of anything if you think of you could make
anything if you think of you could make
anything if you think of you could make with these legos now you can make here
with these legos now you can make here
with these legos now you can make here with this system so it’s pretty exciting
with this system so it’s pretty exciting
with this system so it’s pretty exciting while this is I think a very exciting
while this is I think a very exciting
while this is I think a very exciting application I think the more exciting
application I think the more exciting
application I think the more exciting and more impactful applications are the
and more impactful applications are the
and more impactful applications are the medical domain those are the ones
medical domain those are the ones
medical domain those are the ones actually hit closer to home for me and
actually hit closer to home for me and
actually hit closer to home for me and I’ll tell you why
I’ll tell you why
I’ll tell you why so growing up and part of a big Italian
so growing up and part of a big Italian
so growing up and part of a big Italian family so this is a picture of me and
family so this is a picture of me and
family so this is a picture of me and all my cousins on one side and family is
all my cousins on one side and family is
all my cousins on one side and family is that my grandfather’s birthday party a
that my grandfather’s birthday party a
that my grandfather’s birthday party a couple years ago we always have a great
couple years ago we always have a great
couple years ago we always have a great time we’re together and usually the life
time we’re together and usually the life
time we’re together and usually the life of the party is my cousin gel which you
of the party is my cousin gel which you
of the party is my cousin gel which you can see here next to me
can see here next to me
can see here next to me about four years ago Joe suffered a
about four years ago Joe suffered a
about four years ago Joe suffered a massive stroke so a stroke is when you
massive stroke so a stroke is when you
massive stroke so a stroke is when you have a blood clot moves from somewhere
have a blood clot moves from somewhere
have a blood clot moves from somewhere in the body into the brain it cuts off
in the body into the brain it cuts off
in the body into the brain it cuts off blood flow to the brain if you’re lucky
blood flow to the brain if you’re lucky
blood flow to the brain if you’re lucky you can get a drug and it can dissolve
you can get a drug and it can dissolve
you can get a drug and it can dissolve this this this clot or the surging it’s
this this this clot or the surging it’s
this this this clot or the surging it’s in a place in the brain where the
in a place in the brain where the
in a place in the brain where the surgeon can go when you remove it
surgeon can go when you remove it
surgeon can go when you remove it himself in Joe’s case in other people’s
himself in Joe’s case in other people’s
himself in Joe’s case in other people’s cases it can be in a deeper part of the
cases it can be in a deeper part of the
cases it can be in a deeper part of the brain where it’s hard to get out and
brain where it’s hard to get out and
brain where it’s hard to get out and then the people can suffer with this
then the people can suffer with this
then the people can suffer with this condition for quite a while and Joe
condition for quite a while and Joe
condition for quite a while and Joe suffered about two years before he
suffered about two years before he
suffered about two years before he passed away with this so this is
passed away with this so this is
passed away with this so this is definitely an unscripted event in Joe’s
definitely an unscripted event in Joe’s
definitely an unscripted event in Joe’s life in my life but I think these events
life in my life but I think these events
life in my life but I think these events you can also use for inspiration and
you can also use for inspiration and
you can also use for inspiration and motivation so now one of my goals is can
motivation so now one of my goals is can
motivation so now one of my goals is can we design a robot if we can use for the
we design a robot if we can use for the
we design a robot if we can use for the applications like this where the surgeon
applications like this where the surgeon
applications like this where the surgeon can’t get up the blood clot but the
can’t get up the blood clot but the
can’t get up the blood clot but the robot can can remove that and help
robot can can remove that and help
robot can can remove that and help people like Joe to recover learn and
people like Joe to recover learn and
people like Joe to recover learn and return to a healthy life other
return to a healthy life other
return to a healthy life other interesting medical applications that
interesting medical applications that
interesting medical applications that are they’re targeted drug delivery
are they’re targeted drug delivery
are they’re targeted drug delivery so these micro robots remember very
so these micro robots remember very
so these micro robots remember very small they’re run the same size of of
small they’re run the same size of of
small they’re run the same size of of cells and also tumors so you can load
cells and also tumors so you can load
cells and also tumors so you can load this with the drugs if you can precisely
this with the drugs if you can precisely
this with the drugs if you can precisely control where it’s going to go you know
control where it’s going to go you know
control where it’s going to go you know what’s going to get to the tumor site
what’s going to get to the tumor site
what’s going to get to the tumor site you can actually put a lot more drugs on
you can actually put a lot more drugs on
you can actually put a lot more drugs on this and you can how it’s efficiently
this and you can how it’s efficiently
this and you can how it’s efficiently done because those drugs traditionally
done because those drugs traditionally
done because those drugs traditionally will get diffused to everywhere in the
will get diffused to everywhere in the
will get diffused to everywhere in the body so you can have higher
body so you can have higher
body so you can have higher concentrations of drugs getting to the
concentrations of drugs getting to the
concentrations of drugs getting to the target site if you can be delivered with
target site if you can be delivered with
target site if you can be delivered with these micro robots hopefully get some
these micro robots hopefully get some
these micro robots hopefully get some better patient outcomes that way another
better patient outcomes that way another
better patient outcomes that way another application we break your therapy in
application we break your therapy in
application we break your therapy in this case you have these radioactive
this case you have these radioactive
this case you have these radioactive seeds which need to be delivered to the
seeds which need to be delivered to the
seeds which need to be delivered to the tumor site for cancer treatment again
tumor site for cancer treatment again
tumor site for cancer treatment again you can have Micro robots deliver these
you can have Micro robots deliver these
you can have Micro robots deliver these to the to the site rather than having a
to the to the site rather than having a
to the to the site rather than having a very invasive procedure done which is
very invasive procedure done which is
very invasive procedure done which is currently done so hopefully this
currently done so hopefully this
currently done so hopefully this wouldn’t help with recovery don’t forget
wouldn’t help with recovery don’t forget
wouldn’t help with recovery don’t forget better outcomes as well you also can use
better outcomes as well you also can use
better outcomes as well you also can use these micro robots for biopsies you can
these micro robots for biopsies you can
these micro robots for biopsies you can add these little spikes or spokes to the
add these little spikes or spokes to the
add these little spikes or spokes to the end of the robot you can then use them
end of the robot you can then use them
end of the robot you can then use them to travel inside the body take a tissue
to travel inside the body take a tissue
to travel inside the body take a tissue sample bring it
sample bring it
sample bring it and in figure out if it’s Kant if a
and in figure out if it’s Kant if a
and in figure out if it’s Kant if a cancerous tumor or not and hopefully
cancerous tumor or not and hopefully
cancerous tumor or not and hopefully again less invasively that it’s
again less invasively that it’s
again less invasively that it’s currently done right now so the bottom
currently done right now so the bottom
currently done right now so the bottom line is these micro robots and offer
line is these micro robots and offer
line is these micro robots and offer unprecedented capabilities that you just
unprecedented capabilities that you just
unprecedented capabilities that you just can’t get with these larger macro scale
can’t get with these larger macro scale
can’t get with these larger macro scale robots I mean the future we hope to have
robots I mean the future we hope to have
robots I mean the future we hope to have these micro robots around the same size
these micro robots around the same size
these micro robots around the same size of red blood cells with onboard
of red blood cells with onboard
of red blood cells with onboard computers cameras intelligence arms
computers cameras intelligence arms
computers cameras intelligence arms hands and all the sorts of interesting
hands and all the sorts of interesting
hands and all the sorts of interesting things so we could do a lot of different
things so we could do a lot of different
things so we could do a lot of different healthcare applications so hopefully
healthcare applications so hopefully
healthcare applications so hopefully have a better idea of what a micro bot
have a better idea of what a micro bot
have a better idea of what a micro bot is now and you can be excited about
is now and you can be excited about
is now and you can be excited about these applications as I am in the future
these applications as I am in the future
these applications as I am in the future if you can think it the microbots can do
