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

[256gej]

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

[TheScreeb]

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

[chandigorom]

can it masterbade my penis?

[boapirak1]

It is work and how to grip, Pl explain

[zzzmind]

I hope Doraemon is Real in future

[dashin999]

Doraemon Hand!!!

[LeonPass]

will it blend ??

[imshanedulong]

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

[mystupidstory]

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

[fuemaqueda]

@mystupidstory To prove that it was a real egg and not a fake plastic one

[mystupidstory]

@fuemaqueda oh. okiz..

[thejamesonthestreet]

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

[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.

[lkjune]

Can this robot hand pick up a piece of paper?

[VulcanFleet]

@lkjune I want to see that, and putting a thumbtack into a wall.

[doglessliberal]

Now I can get robots to pick up all my moped shock absorbers while I kick back and relax...

[merrickal]

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

[RiverofDoubts]

Lol I did the same thing in elementary school with the straw that came with my milk; guess that makes me genius.

[livermoore]

porous elastic material... 10 points!

[txvoltaire]

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

[TheSafecracker777]

Take the red pill

[buceta1967]

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

[0729mooncave]

この技術の是非介護に応用して欲しい。

[careerschooladvisor]

interesting...what does this have to do with doramon?

check out my videos on education!

[imm10999]

will it pick up dog shit?

[Nonanepod]

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

[TempleOfSin]

I can't believe we're going to be conquered by robots that have coffee for hands.

Who knew that of all things, we'd wind up tending coffee fields in the future, to supply our robot overlords with filling for their gripping appendages.

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/

[skatekoh]

can this please my....

o.-

....

....

no?

[Raptorrob]

Imagine these tools in the homes of the elderly! I predict they will soon help our loved ones to prepare food, assist them in writing letters, and then turn on them suddenly one day.

[TheBadunka]

@Raptorrob Fan of isaac asimov?

[tacorainsasa]

doraemon's generation is coming!!!!!!!!!!!!!!!

[dxdx100xkx]

哆啦A梦的圆手！：D

[ahmao95]

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

[pattrickd]

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?

[TheRyoKato]

this is certainly DORAEMON's hand.

[chanhow521]

Wooooo!!  Is so cool

[mirceaingi]

its adhesive too

[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?

[takacova]

ドラえもん、の手なり。

[TheNesk7]

凄いっす！　やわらかそうですなあ

[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.

[n33oh]

@onefineline 1- okay

2- cuz $ is a finite proposition

3- yes, that would be cool

[Lessthantito]

@onefineline Three: exactly what I was thinking combine both= robot overlord

[alexkarate]

great job!!!

[recorriendo]

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

[dragonrocklive]

Doraemon, let's play rock paper scissors!!!

[laiklang]

@dragonrocklive LOL!!!!!!

[melchior00625]

@dragonrocklive "Argh! Stop that! You know I can only use 'rock'!!"

(And yet he'd go for it anyway.. XD )

[DGZlol]

Hi Doraemon :D

[VitinhoF24]

Can this shit do my homework?

[arsrobots]

Always good to see an A465 used in research. Very creative. Americanrobot sales.com

[KiranGlitch]

lol at 1:35 !

[fodass666]

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

[bbsonjohn]

Next test grip object: dorayaki

[beawsian]

Doraemon's hand.

[meemat]

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

[vinh291]

silly robot, thats a square!

[AzianBaka]

Doraemon may not be as far away as i though...

[mrmeteor1957]

@compact3: The Universal Gripper has approximately enough strength to pick up a bag of apples.

[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!

[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.

[zjtlove]

@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.

[HooDwin12]

whatta beast.

[MythOfEchelon]

Disable sound to make it more magical.

[collosuz]

DORAEMON HAND!

[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.

[Compact3]

@n33oh I was afraid of the too. However, is it the design that makes it unstable and inaccurate or this particular implementation? I think the design isn't the bottleneck. If you use a fluid with very low viscosity (instead of the coffee) that can turn into a solid by command and back again; and if you replace the balloon with a material that is FAAAR more elastic/stretchable/deformable and yet still strong: then it WILL be stable and accurate I think.

[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.

[Compact3]

@n33oh Why does it need sensors to pick something up? This implementation doesn't have sensors and it does it's job perfectly. An eye (camera) is more than enough.

[n33oh]

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

[Compact3]

@n33oh yes, I know it's important to know the orientation of the object you're holding to be able to actually DO something with the object. However, you don't need touch sensors over the whole surface for that. You can also work out the orientation of an object with a camera and some very advanced software.

[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?

[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)

[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.

[TempleOfSin]

@Compact3 How about dry cornstarch? I wonder if that would work.

[Compact3]

I wonder how much grip it has. In other words, how much force do I need to pull something out of the "hand". Or how much weight can it carry?

[Lloyf]

now make robotic hand with these balloons in each fingertip

[Compact3]

@Lloyf that wouldn't work as good as this I think. The surface of the balloon has to be relatively big for it to work.

[Lloyf]

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

[Compact3]

@Lloyf dunno, it's kinda hard for me to visualize how that would work. try it! :-P

[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.

[mile0chicken]

@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.

[pgatmait]

@mile0chicken ok. thanks for clearing that up.

[therealsuperhobo]

Ingenious

[seedmanee]

doraemon's hand

[melchior00625]

@seedmanee I was thinking the exact same thing-- now all the robot geeks in Japan need is a 4-dimensional pocket.

[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.
