Locomozione: dagli umani ai robot umanoidi | Emanuele Quarin | TEDxPadovaSalon


hi all I wanted to start

telling my story a little bit

personal and I wanted to start with one

I remember the memory of my father who

he pretended to work for asylum

I used to hang around by moving needlessly

bricks from one side to the other looking

to reassure my fears of being

abandoned these fears however

they got a little worse when they were old

eight years old

that rascal of my father abandon us

really taken away by cancer

liver not yet forty

and here is that and here is some doctor

of the hospital of Rome of the domain of

if these my fears would be

vanished with the natural flow of the

time

over time I learned to transform

these my fears in a curiosity in the

curiosity to try to understand how to do

move objects around me in

as if they had not followed me

they would have more abandoned memories than

at the age of 11 and example was put

in the head to make a submarine then a

rabat you have a tube a cork a

scooter a pile

and here I wanted to try this

submarine begin to find it for

home but at a certain point the grandmother

he was not at home and he was a genius of genius

fill the freezer at home and the

grandma was not happy at all

he had to knock a lot of material

acquired during the year

today I am a researcher I deal with

locomotion and locomotion

extraordinary ability that objects

year to move even year for

move and in particular I take care of

locomotion for robot humanoid robots

humanoids

and clear that if we talk about robots

humanoids we can not not talk about

human and indeed human beings yes

move into the surrounding environment

thanks to the walk that is that

extraordinary capacity that we

we buy in the first 15 months of life

being we reflect this ability la

here we are in a short time

relatively short compared to

average length of a life of a being

human

and here it is

and here is the question that arises

natural because because beings

humans walk as they walk well

so here there is little to invent and

much to study as much as biology

evolutionary teaches us that we must do one

jump back in time to 6 million

years and return to the land it was

subjected to a lowering of the

temperatures this lowering of the

temperatures induced one in turn

reduction of rain forests e

so if you imagine you are one

chimpanzee living at the edges of these

forests you would not need to

move this need for more

move when when it took when

it happened when it happened on the trees and

he probably induced an adaptation

postural erected fact proves that

chooses rank tango react to

flexibility of the branches exactly

extending the legs then the other requirement

of moving

he probably optimized the energy

the energy spent on locomotion e

so if we were to synthesize

running it is possible that there are two

fundamental elements that have induced

the bipedal walk as we live it today

and manipulation to energy

now probably probably the

manipulation and what it has induced

intelligence and intelligence have us

asked the other question as well other questions

it’s but we can move more

fast from one point to another

and here we have invented a certain

number of systems this is that

they range from the robot fine wheel

humanoid but one of the objectives

fundamental to these systems

especially above all foreigners

it was the speed to move quickly

and that’s why we conceived

very different solutions from those

conceived by nature

certainly the planes fly not banging

the wings, however, what sometimes

we can we can not understand is if

we did better or worse than the

nature well if we take for example

the blackboard which is one of the planes

fastest ever conceived of being

human

we realize that it reaches

a speed of one km per second

and if we compare it with a pigeon

the journey is simple 34 meters per second

it would seem that we have done better

but in reality if we choose another one

unit of measurement that the pig length

body both we aim how many times the

length of one’s body is repeated in

a second

we realize that nature is

still ahead of our systems

locomotion and what we seek

to set up Italian technology

and channel all the knowledge on

locomotion systems in the next

systems that will be able to move

like humanoid robots well it is clear that

if we want to move a robot

humanoid like a human being

you need the journey is along the law

luca as human beings are

extremely capable of moving

in the surrounding environment through i

contacts between your body and

the environment

and if we compare these capabilities that

the human being has with the results

current humanoid robotics well there

we realize that the journey is still there

along for example the barbara darpa

challenger that the olympiad of the robot has

proved that the walk is still one

open problem and it is absolutely not

easy to solve

and here is that before before implementing

control algorithms to move

humanoid robots must understand that

what is walking

well, the extraordinary walk

ability we have to move and

maybe we do not realize it but we

we walk falling and in fact the

walk can be decomposed into three

the fundamental components of the first

balance is really the balance

fundamental component

humans going from quadruped

bipeds have optimized their own

energy can use hands though

they have become unstable and then there are

two other components of the bike

oscillator of the leg trying to

search for contact and then the way

repulsive, that is, what the motion of

contraction of the fundamental leg

during the race and where we implement

we walk these algorithms well

what we want to implement ourselves

we want to implement these algorithms

on a humanoid robot named aicab a cabo

humanoid robot acts roughly little

more than one meter weighs approximately 30 30

kg and is equipped with a number of

sensors the sense is more sensors like the

vision that allow him to see the

microphone that allow him to say but

above all two particular sensors that

I am the skin or if you want to touch the

robot him to the perception of where it is

you are touching and also the sensors of

force force sensors allow us

to understand how strongly

we are touching the robot and right

these internal forces of the robot in

reality I create the movements or the

accelerations and how to generate these that

somehow emulate the contraction

muscle of the human being

if we control the muscles we are

doing internal forces and those

internal forces now I remain standing

because I’m contracting I’m checking

interactions with the external environment ed

here is that if I want to check one

robot in such a way that it is standing

I have to check the interactions between

robot and external environment

these considerations can do

born and that with CCC allow us to

to conceive the control algorithms for

the humanoid robot aicab is the thing

fundamental of these algorithms is that

the robot is compliant thing

means means that an interaction

with the robot it must not first of all do

yes that the robot

but it certainly must not hurt

the operator and this is one of the

fundamental components for the

applications that one day probably

they will be in homes in everyone’s homes

Now

now it is clear that the balance is

certainly a fundamental component

but for walking we need

something more and how we can

to conceive walking algorithms and

so here there are years of literature

that explain how to do it

like trying to make a walk

robot

however if we simplify the robot in

one of the tools that probably has

revolutionized science like the pendulum

then a first indication of where

put the foot can be that

position where the pendulum stops

exactly in a vertical position

well then this simple observation

it allows us to make ourselves conceive

of control algorithms for robots

humanoids giving them the chance to

move in space however we like

researchers we need to

go beyond not only from the point of view

practical but also theoretical and therefore the

question that you must ask yourself ok

what can we imagine later and we can

imagine a scuba diver ad

example able to operate in

very difficult conditions

or a hybrid robot instead of

have legs on wheels though

again if you should

ask me how the future imagines

humanoid robots well I can not not

imagine a future where these robots

are able to fly and allowing us

to move in a fearless way is the

definitely less obsessive way

compulsive thanks to everyone

[Applause]
