For those interested, the song/music when the robot is dancing is "Surrender" by Jami Sieber.
I want to have a tiny version of this to put it on my desk! :-D
Definitely the first robot I've seen that would fit into most everyday situations with humans. I can't wai until they start showing up in different places!
So awesome! Can't wait till it starts jumping around!
id like to see this thing traversing the bumpy surface of mars.
Walking out on stage with a robot = Instant thumbs up before even watching.
Great background on this rapidly evolving technology. Viewed after seeing updated Alden version of this prototype!
This is way better than that segway device...
I guess this can work well for balancing and not tipping over compared to something tall on multiple wheels. Especially if the ball is made larger and rougher so that even in position when electronics are on the side it could lift it up.
Basing motion on instability also has the side effect that everything is quite slow as you have to wait for the tilt etc. Each time you do something there is a relatively large ramp up time compared with other methods of translation and rotation.
finally a robot with some balls !
@VoiceOfAleppo Back when i was looking at AI most of the NN problems tackled seemed to be linear relationships. It always seemed to be a bit more interesting to try and develop a model of something which was non-linear. Balancing seems like a good example of such a project and it would be fun to see what sort of system would be needed to be able to learn how to balance.
I will would like 3 of these to serve drinks at my next party
This could also be a moving shelf. you can have your lets say remote, phone, etc etc and just call it "Rezero" and it detects where you are with a heat sensor so that way you wont have to look for things remembering you usually leave it on rezero. also, it can be used as an object transportation device. damn, i can think of so many uses for this.
Watching it dance with the music turned off is like watching a desperate cry for help
@fankipete go for it dude, and congrats for a great start.
It's adorable :3
Beautiful!
Splendid!
@SalixAlba256 VioceOfAleppo pointed it out correctly. The control is based on a mathematical model of the mechanical system and forms a explicit feedback law from the sensors to the motors.
This is really cool and amazing stuff. I wonder if they could add a feature that can allow it to get back to it's fe..., I mean it's ball when it falls down.
@MrIntelligenius Most students of our team are mechanical engineers and we worked together with 2 electrical engineers. You can find all the team members on our website about the project Rezero.
for those people wondering why the giant ball exists even though it only makes the robot unstable, the inherent instability is the reason why the robot is so agile. it has a much lower response time.
@dumbnetworks You are right, an automatic stand up mechanism would be desirable in the future. Rezero is our first prototype and a lot has to be improved and added to make to a safe product.
If anyone knows, what's that song its dancing to? Appreciate it. :)
@LanceFlugerman What advantage would that have over wheels?
Instant thought? Could follow me around with a tray holding beer and nachos!
what would happen if it goes through a puddle? would the wheels controlling the ball lose traction and would it be able to compensate for it?
Curious as to the algorithm they use to restore balance. Is it a explicit algorithm or some kind of neural net or adaptive system?
@VoiceOfAleppo Cool, thank you. We are glad you like Rezero.
@jvillavic Thank you! I thought the same thing!
love it
@0rnJ
Yeah, have you seen "I, Robot" ?
Gather an entire 'troupe', dress with creative costumes...a ball ballet.
Flat clean surface only. Would not do well at my house full of toys. And cables and pets. Well done guys.
@fankipete ok, I wasn't clear enough, what if falls and, more important how does it get up on the ball?
Cup holders, beer and the follow me feature and we're set!
wish some folks would put there heads together and design a powered wheel chair that's comfortable and cheap, and is everything that someone with those needs is met
Make a giant ball point pen to write huge cursive letters across large surfaces to be read from low-flying aircraft.
This applied to cars, would be HUGE.
I love TED videos, but come on, why are they only 480p?
I wondered how they deal with the slip between that ball and the motor wheel
@dumbnetworks Rezero knows from which disturbances it can recover. When a that threshold is reached it turns of the motors in order not to hurt anybody. Then it falls on to the ring that's around the system and absorbs the shock while protecting the mechanics and electronics.
For now, Rezero has to be placed manually on the ball before turning it on.
The practical applications do not require Rezero to climb stairs.
now we have this ballbot the circus doesn't need a clown on a ball anymore
its really good that they're able to construct something like this but they need to make it look more stable...it just looks like a bunch of wires wrapped around a metal stand(with the exception of the bottom half)...but good work any ways
@fankipete Thank you very much :)
NICE ONE
很不错，支持
@kezman2003 They meant unstable because it's CONSTANTLY in motion, not that it will fall over... it can right itself up. So yes, it can certainly carry around those IV bags to follow people in hospital settings... not medical tools or whatever though
Rollers on legs for jumping and pouncing.
wicked cool!
so many ted talks need an speakers addendum "BTW, give us venture capital money"
Finally! Rosie!
I like this robot's name
It will cool to be my personal assistance to carry my shopping bags or grocery.
@dumbnetworks The ring around the robot and the shock absorbers on top protect the robot in case of a crash.
had a cool thought about a one balled vehicle seach it up aready been done
@PaladinPK it sadly would take alot of the stability of the cars steering mechanics. the engines would have to be very very strong at high speed to redirect the cars direction. :( would be epic tough :)
asimo just got served.
That's great, but what about using a wheel instead? It might be much more difficult, as the robot would need counter weights or something I guess, but that'd be even more impressive.
its cool, i like the idea that it can be used to carry medical equipment.. smart. =)
@PaladinPK Not even goodbye, we would be saying hello to TRULY parallel parking. Parking that is done while parallel! :)
What is the point?
That is so fucking cool.
@LanceFlugerman
The surface needs to be smooth on the ball. It wouldn't make a very good terrain vehichle.
They should have had it take a bow at the end by rolling backwards then forwards :)
That's niiiiiice! :D
@meseplus that's why he created the ballot to make himself taller
A nice idea without wheels, great!!!
it should have took a bow at the end! awesome though.
Hey, in the TV-show Caprica some of those bots got shot by the first Cylon. But I guess this little Rezero fellow would be a bit too expensive for target practice...
@MrIntelligenius it's a mix of electronic engineering and computer science, aka robotics.
fricken lasers attached to their ballbot's head
First thought I had was for filming without the need of rails and shit. Establish pattern, keep distance from objects and people, etc.
I want one
Oh on the applications themselves: I think the hospital one would really work out though it'll be quite some time before we see them, and the ride "might" be acceptable by society... idk, first look at it reminded me of Mr. Garrison's "It" in it's "practicality"...
nice
where'd they get that giant mouse ball
there's some smart people out there..
Robot, fetch me a beer!
4 of them would make good leg components on a battle tank unit. Jus sayin.
Reminds me of those Dwarvan spheres on Skyrim.
Some of you who are from UK may be familiar with this type of robot from ZX Spectrum games, like Quazatron where robot Klepto was sent to kill bad robots on planet Quazatron. (check UA-cam for Quazatron Speccy)
i want one
a waiter to bring you drinks
What happens if it's pushed with a lot of force?
Rosie the Robot!
@Crazee108 are you serious? Even the designers started the talk by saying it's an UNSTABLE robot, and you agree with the idea of it carrying around medical equipment??
very cool, can i order 3 to server as waiters in my starwars themed bar?
Can we have cars with spherical wheels like in "I Robot"?
@shrodingersman 1 ball to be exact
@fankipete well I was wondering this because you want to use it as an info "bot" so if a kid slaps it this thing falls down so is basically game over, until some good samaritan puts humpty dumpty back online. Or not?
I was searching up Re:Zero
CEEcee Grey my brain trembles
I would love to have one of these follow me around in public and be my "pet." People would be like... "Uhhh, you got a robot following you." -- "OH, that? Naw, it's my pet." -- "o_O"
Hasn't Honda already invented something like this?
I want one to serve me drinks...
Small size and ergonomic wheelchairs! :)
very promising..
an inside out mouse (with ball ) actually !!
