Universal Gripper: Grabbing, Drawing, & Pouring

[@whoishober]

Amazing part of this thing is the simplicity The human hand has a lot going on when it picks something up. Dozens of muscles, joints, bones, nerves etc. This gripper is on the opposite side of the spectrum & yet does the same task. "The gripper was designed to allow robots to pick up various objects without a lot of computational overhead" "Upon application of a vacuum the granular material contracts & hardens quickly to pinch and hold the object without requiring sensory feedback" very cool!

0:32 for some reason I though that scene was absolutely adorable and it made me smile.

[@meemat]

This is amazing, especially the egg! Nice job guys!

[@Dr.Claudioagmfilho]

wow i am from Brazil in south america and i loved this video from down here...

[@DarkFiber23]

@pgatmait You are somewhat wrong. There is negative pressure, but that only removes air from the balloon. After the air is removed, the balloon is hard, so it is able to maintain a grip on the object it conformed around.

[@mythofechelon]

Disable sound to make it more magical.

[@n33oh]

@Compact3 I think you're on the right track, but the ball would also have to have sensors all along its skin so it knows the orientation of the object in its "hand." With a hand and 5 fingers design, you only have to worry about 5 sensors. With a round ball, you'd need sensors all around that thing.

[@SexChatClub]

Wow, it poured water perfectly!

[@pgatmait]

It's a great accomplishment, but it isn't so much a hand as a porous surface with negative pressure (suction) keeping the target object in place.

[@n33oh]

@ughrew take a cup in your hand, close your eyes. turn the cup upside down or 180 degrees. or turn it sideways, 90 degrees. make sure your eyes are closed the entire time.

[@-beee-]

Love this

[@vp21ct]

This is how My Little Pony hooves work! :D

[@vitalramrayankula1712]

Universal Gripper--yes it is!!!!

[@recorriendo9260]

lol I guess those having mentioned Doraemon are all from taiwan since people in US mostly don't know who Doraemon is

[@CalvinK]

How about plucking? This hand seem to require pushing against the object to form the shape then pick it up... what if the object is in the air or floating in water?

[@n33oh]

@onefineline 1- okay 2- cuz $ is a finite proposition 3- yes, that would be cool

[@n33oh]

@Compact3 Think harder about why it would need it to be viable for real world manufacturing or even daily use.

[@Lloyf]

@Compact3 What if you had hundreds of them small enough to fit on a finger tip. Would that work?

[@sailfast2005]

This looks great and simply solves a challenge of robotics. Another test for you - screw a bottle cap back on a bottle (starting with the cap top-down to the table). Also, have you thought of making a hand with the palm as coffee grounds and each fingertip as coffee grounds so you can manipulate fragile objects?

[@pgatmait]

@mile0chicken ok. thanks for clearing that up.

[@eliwright2580]

That's amazing.

[@LeonPass]

will it blend ??

[@merrickal]

Doreamon's Hand! The future is at hand (pun not intended), shall we see fully functional cat-robots walking about by 2023?

[@HooDwin12]

whatta beast.

[@MrDanilo1601]

excelent idea

[@fodass666]

My vacuum cleaner tube with a pierced softball does the same thing :D

[@thekingfotheav]

時間已經進入了21世紀，我們的科技也終於快要追上哆啦A夢的時代了！芝加哥大學和康奈爾大學所製作(奇怪，怎麼不是日本人？)的這隻萬用機器手成功的實作了哆啦A夢的饅頭手：藉由一個暗藏玄機的氣球體，這隻機器手可以拿起任何他碰的到且大小上握的住的東西。方法說起來也很簡單：首先在這個氣球裡填滿...咖啡粉(咦？)，然後在球體碰到並包住物體時，把裡面的空氣抽出─這樣可以讓咖啡粉和氣球都暫時呈現固體狀，提供的力道足以拿起物體。至於要放開時也很簡單，把氣充回去就好了。chinese.engadget.com/2010/10/28/university-of-chicago-cornell-researchers-develop-universal-rob/

[@arjunv]

wanna tell me why he took out the tissue, before dropping the egg???

[@Gottenhimfella]

so egg would break, proving that it had picked up a raw egg, not a cooked one

[@n33oh]

@Compact3 Manufacturing robots today can be as simple as 1 finger + 1 thumb, up to 4 fingers + 1 thumbs. Still far less sensors than what this would require and they wouldn't need any additional software or video system to know the orientation of the object they are holding. Instead of adding more complexity in order to try to do what existing designs can do, why not improve on existing design? Stronger "muscles" faster, more nimble response like human hands?

[@chanhow521]

Wooooo!! Is so cool

[@mrchaid]

oh! It's a doraemon

[@hae-sookim4404]

도라에몽

[@mirceaingi]

its adhesive too

[@AbiNubli]

DORAEMON HAND!

[@BrainSurg101]

Dis is sick

[@LeongKokJune]

Can this robot hand pick up a piece of paper?

[@arjunv]

@fuemaqueda oh. okiz..

[@takacova]

ドラえもん、の手なり。

[@beawsian]

Doraemon's hand.

[@TheScreeb]

Finally! I was sick of having to bend over to pick up all my tetrahedrons

[@emmanuelalvarado4077]

So what happens when, there is a failure in the air supply?

[@BogdanHarasymowicz]

It doesn't work. You also might be surprised when you discover that it doesn't work if there is no electricity supply.

[@VulcanFleet]

At 1:40 I said, Oh My Science this is awesome, if they can make one that can write they win the Internet. At 2:20 they won the Internet.

[@256gej]

Why the hell would you move the paper towel before you drop the egg??

[@Gottenhimfella]

So the egg would break, proving that it had picked up a raw egg, not a cooked one

[@ughrew]

@n33oh human hands are NOT always the best solution, because they require lots of sensors and controls (eyes, fingers, a big brain...). This solution is incredibly cheap and simple, and could have industrial handling applications (still the vacuum is quite slow for light objects manipulation, but they can improve that)

[@donpeli3]

Doraemon！

[@kim_baseball]

Doraemon! I find your hand!

[@thephalewail]

It would be funny if it wrote "please kill me"

[@alweilin]

小叮噹的手已經做好了^^

[@hackeritalics]

WHAT IS THIS BLACK MAGIC?! So fucking cool... I want it for my robot arm. lol

[@hackeritalics]

I just saw how to MAKE this black magic using coffee grounds, a balloon, and funnel. You can bet your ass I will be making one of these. haha

[@onefineline]

@n33oh - Well for one, manufacturing isn't the only application for robots. Two - Why is developing alternatives to current robot technology a bad thing? Why would we want to stay stuck on one technology? Look at film vs digital photography. In the early days of digital, the technology was limited compared to film. But today, digital utterly dominates. Three - Who says the technologies can't be used at the same time? Imagine traditional robots with this technology on individual fingers.

[@VideoZJ]

@n33oh You have to walk before you can run & it takes many steps to get to the finish line. We'd be wasting money on research if we didn't accept every milestone of progress. Also remember, the purpose of machines is not to replicate nature, if it was, cars would have legs rather than wheels. Right tool for the right job... sometimes a hammer is the right tool, other times a screwdriver.

[@whovianbrony]

This explains earth ponies...

[@Lloyf]

now make robotic hand with these balloons in each fingertip

[@imshanedulong]

But can it pick up... A UNIVERSAL GRIPPER?

[@dashin999]

Doraemon Hand!!!

[@ashleyalvarez6025]

Powerpuff girls

[@bBozo]

SKYNET SKYNET SKYNET SKYNET SKYNET

[@txvoltaire]

This will be great once someone can figure out how get rid of that Darth Vader breathing!

[@thejamesonthestreet]

i bet that the creator inspired by a simple cartoon, Doraemon :D

[@TheRyoKato]

this is certainly DORAEMON's hand.

[@VitinhoF24]

Can this shit do my homework?

[@0729mooncave]

この技術の是非介護に応用して欲しい。

[@bbsonjohn]

Next test grip object: dorayaki

[@zzzmind]

I hope Doraemon is Real in future

[@dxdx100xkx]

哆啦A梦的圆手！：D

[@proxy90909]

Powerpuff girls explained

[@nanoxlasher]

@dragonrocklive LOL!!!!!!

[@kev85238]

good work guys, can you get it to pick up all my dirty clothes and use the washer and dryer. I would really appreciate it.

[@seedmanee]

doraemon's hand

[@tayjacsmith]

so you could tell it was raw

[@leemarnen6035]

Doraemon!!

[@Nulono]

That's drawing, not writing.

[@Nonanepod]

I think it looks like having something hygiene problems on practical use.

[@mrblue251]

Hello from tumblr

[@n33oh]

Novel BUT unstable and inaccurate. There's a reason why nature designed humans to have hands and not stubby balls on the ends of our wrists.

[@ahmao95]

cant use on a human.....it need suck up the air inside the ball

[@n33oh]

I'd rather see money spent on research trying to better mimic what already works so well in nature...a hand with 4 fingers and an opposing thumb.

[@richardsjpark]

can this please my.... o.- .... .... no?
