High-Speed Robot Hand Demonstrates Dexterity and Skillful Manipulation

Ishikawa Komuro Lab's high-speed robot hand grasping grain of rice using tweezers.

A few blogs are passing around videos of the Ishikawa Komuro Lab's high-speed robot hand performing impressive acts of dexterity and skillful manipulation.  However, the video being passed around is slight on details.  Meanwhile, their video presentation at ICRA 2009 (which took place in May in Kobe, Japan) has an informative narration and demonstrates additional capabilities.  I have included this video below, which shows the manipulator dribbling a ping-pong ball, spinning a pen, throwing a ball, tying knots, grasping a grain of rice with tweezers, and tossing / re-grasping a cellphone!

Here is the video:


Based on the video, the hand uses high-speed actuators with harmonic drive gears.  The hand can close in 1/10th of a second!  Personally, I find the tweezers grasping the grain of rice the most entertaining -- very anthropomorphic.

calm down its just a robot!!!Yell
Why is it learning to knot a rope? For when they become self aware and hang us all?

I have many arguments that I would like to make and I am sure I will miss out alot of what I want to say and some of it won't make sense

good time to start learning robotics..... then you can create the next big thing and sit back and enjoy the benefits of unlimited wealth instead of writing your pointless comments on how robots are gonna kill you. Guess what.... you are going to die one day anyway...........

Seriously though, all of you scaremongers out there that are scared of robots coming alive and killing us need to learn something about yourself, allow me to explain.

Humans tend to kill only what we are scared of (and what we want to eat)

Robots have no need to fear us - they can make themselves indestructible and unless they see us as food - which they won't, as there are cleaner more efficient fuels allready, and more that are yet to be discovered.

we are safe, and only need be worried about how to occupy ourselves now that robots are doing all the jobs.

If robots had all the jobs in the world what would they be making, as no human would have any money to buy it anyway.  So what is the point in automating everything.

It is the selfish nature of humanity that is the problem,  not the robots we create to make us more money....

Humans have been learning for hundreds of thousands of years and pass that information along. Robots would have to start right at the beginning, knowing only what has been programmed to them. But you might say they can harness the internet - first they have to find a way to interface with the internet, but before they do that they have to actually know that the internet exists, and even when they do find the internet and a way to obtain its data all they will get is Wikipedia and its 50% BS content,  so lets start now by creating a wikipedia page on the top 10 things a robot needs to survive and feed them some bs that will actually destroy them - sound good huh?

And if all else fails no robot is safe from an EMP


I´m completely dumbfounded. There are no words that suitably express my amazement at this feat of engineering or the hope it instills in me.

It is on par with love.

oh aren't we?, think about it, first you need to know what life is anyway, then you need to consider that modern programming makes it entirely possible to create a virtual brain, even though it would take a supercomputer (and those often take up several rooms), still think about how quickly computers that are capable of modern day cell phones shrunk from several football fields in size, to something smaller than the gadgets in sci fi movies (at the time). besides, for every brain cell in the human brain, there is a computer connected to the internet, it isn't a question of will people try to make a skynet, it is a question of when
awesome work man!!! keep up the good work. people like you guys can only make this world a better place by understanding more of what we could explore within our reach....

LOL! I like your comment, be colonized by robots! great dream! and after all why not!

well the theory for the atom bomb started as an exiting find for scientist never aware of the great damage it would produce in the future iven if this is a stupid robot hand with incredible motion detection program it could be the beggining of something much much worse...maybee not the DESTROY ALL HUMANS theory but imagine all the people that will be remplace becouse of  a more capable worker...with the power and speed of ten ....basicaly there will be no more use for the human
Unbelievable.  Omg. The technology of our time is only going to get more wonderful!

I am in favor of having robots doing all work that humans don't want to do! My biggest question when you think about Asimo for example is why our political leaders are not pushing the industry to quickly make them available?

Now, this being said, the biggest question is what kind of society model will appear once robots will be be every where? Do you realize that the ones who can make robots will not need 90% of humans any more?

Our planet could soon become a heaven for this little part of the population that today is called millionaires ;-)



Agreed.  The existence of robots that can outperform humans should scare everyone.....

Take a full five minutes (one nanosecond in robo time) then think it through everyone,  and see what you come up with.




I completely agree with your statement, Buyck. With technology rapidly propelling at lightning speeds, it's not surprising that robotics are becoming more advanced. It won't be long before robots such as this robotic hand develop some sort of pseudo intellectual (no emotions, of course) and providing answers to questions we've been asking for years. I mean, just good at Watson:

Convincing post Matt... a little TOO convincing.  As if your post was CALCULATED to make us lower our defences.  And your mimicry of our human informal internet writing style was carried out with MACHINE-LIKE precision...  but we know what you are...  

The butlerian jihad may still be upon us, nice work in the servo/motion control the fingers catching the cell phone is pretty good - quite amazing actually - would like to see several sequential attempts and how the overall system coped with those random throwing variations...





There are many things to worry about besides the technophobia (same as that in the 1800s)  you display. Do you think we should outlaw tech because someone losses his job. Buggywip makers unite. Your misconception is that we all lose by the new tech. But the number of people out of work today is far more than the total population of the million year ago full employment. Not to mention the 25 year life span of 16 hr days just keping alive.

The only way we can keep the number of people alive today is through technology. Without it 80 % would likely die of deases or starvation or exposure.
