Péter Fankhauser: Meet Rezero, the dancing ballbot

Prevodilac: Aleksandar Diklić Lektor: Ivana Korom

Let me introduce to you Rezero.

Dozvolite da vas upoznam sa Razerom.

This little fellow was developed

Ovaj mališan je razvijen

by a group of 10 undergraduate students

od strane grupe od 10 mlađih studenata

at the Autonomous Systems Laboratory

u labaratoriji Autonomous Systemsa

at ETH-Zurich.

na švajcarskom saveznom institutu za tehnologiju u Cirihu.

Our robot belongs to a family of robots

Naš robot pripada familiji robota

called Ballbots.

zvanih Ballbots.

Instead of wheels, a Ballbot is balancing

Umesto točkova, ovi roboti balansiraju

and moving on one single ball.

i pokreću se na jednoj kugli.

The main characteristics of such a system is

Osnovna karakteristika ovakvog sistema je

that there's one sole contact point to the ground.

ta da postoji samo jedna dodirna tačka sa podlogom.

This means that the robot

To znači da je robot

is inherently unstable.

sam po sebi nestabilan.

It's like when I am trying to stand

To je kao kad ja pokušavam da stojim

on one foot.

na jednoj nozi.

You might ask yourself, what's the usefulness

Možda ćete se zapitati, koja je korist

of a robot that's unstable?

robota koji je nestabilan?

Now we'll explain that in a second.

Sad ćemo objasniti i to, samo sekundu.

Let me first explain how Rezero

Provo želim da objasnim kako Razero

actually keeps his balance.

održava svoju ravnotežu.

Rezero keeps his balance by constantly

Razero balansira time što konstantno

measuring his pitch angle with a sensor.

meri svoj ugao naginjanja senzorom.

He then counteracts and avoids toppling over

Nakon čega odreaguje i izbegava prevrtanje

by turning the motors appropriately.

okretanjem motora na odgovarajući način.

This happens 160 times per second,

To se događa 160 puta u sekundi,

and if anything fails in this process,

a ako nešto otkaže u ovom procesu,

Rezero would immediately fall to the ground.

Razero će odmah pasti na zemlju.

Now to move and to balance,

Da bi se kretao i uspostavio ravnotežu,

Rezero needs to turn the ball.

Razero mora da pokreće kuglu.

The ball is driven by three special wheels

Kuglu pokreću tri specijalna točkića

that allow Rezero to move into any direction

koji omogućuju Razeru da se pokreće u svim pravcima,

and also move around his own axis

a takođe može da se okreće oko svoje ose

at the same time.

u isto vreme.

Due to his instability, Rezero is always

Zbog svoje nestabilnosti, Razero je uvek

in motion. Now here's the trick.

u pokretu. U ovome je trik.

It's indeed exactly this instability that allows

Njemu je potrebna baš ta nestabilnost koja omogućava

a robot to move very [dynamically].

da se kreće vrlo dinamično.

Let's play a little.

Igrajmo se malo.

You may have wondered what happens

Sigurno ste se zapitali šta se dešava

if I give the robot a little push.

ako ja malo gurnem robota.

In this mode, he's trying to maintain

U ovom režimu, on pokušava da održi

his position.

svoju poziciju.

For the next demo, I'd like you to introduce

Za sledeću demonstraciju, želeo bih da vam predstavim

to my colleagues Michael, on the computer,

moje kolege Majkla, on je za računarom,

and Thomas who's helping me onstage.

i Tomasa, koji će mi pomoći na sceni.

In the next mode, Rezero is passive,

U sledećem režimu, Razero je pasivan

and we can move him around.

i mi možemo da ga pomeramo.

With almost no force I can control

Uz minimalne napore mogu da kontrolišem

his position and his velocity.

njegovu poziciju i brzinu.

I can also make him spin.

Mogu da ga zavrtim.

In the next mode, we can get Rezero

U sledećem režimu, možemo zadati Razeru

to follow a person.

da prati osobu.

He's now keeping a constant distance to Thomas.

On sada održava konstantnu razdaljinu od Tomasa.

This works with a laser sensor

Ovo mu omogućava laserski senzor

that's mounted on top of Rezero.

koji je montiran na vrhu Razera.

With the same method, we can also

Istim metodom, možemo takođe

get him to circle a person.

zadati da kruži oko osobe.

We call this the orbiting mode.

Ovo zovemo režim kruženja.

All right, thank you, Thomas.

U redu, hvala Tomas.

Now, what's the use of this technology?

Sada, koja je upotreba ove tehnologije?

For now, it's an experiment, but let me

Za sada je eksperiment ali dozvolite mi

show you some possible future applications.

da vam pokažem neke od mogućih primena u budućnosti.

Rezero could be used in exhibitions or parks.

Razero moze biti korišćen na izložbama ili parkovima.

With a screen it could inform people or show

Sa ekranom može da informiše ljude ili ih

them around in a fun and entertaining way.

vodi okolo na zanimljiv i zabavan način.

In a hospital, this device could be used to

U bolnicama, ovaj uređaj može se koristiti za

carry around medical equipment.

nošenje medicinske opreme.

Due to the Ballbot system, it has a very small

Zahvaljujući Ballbot sistemu, vrlo malo utiče

footprint and it's also easy to move around.

na okolinu i vrlo lako može da se kreće.

And of course, who wouldn't like

I naravno, ko ne bi voleo

to take a ride on one of these.

da se provoza jednim od ovih.

And these are more practical applications.

A ovo su neke od praktičnijih upotreba.

But there's also a certain beauty

Ali takođe postoji određena lepota

within this technology.

u ovoj tehnologiji

Thank you.

Hvala.

Thank you.

Hvala.
