On the Gripping Hand
eek_the_kat writes "The Sensor Fusion Project at Ishikawa Hashimoto Laboratory has developed a high speed visual feedback system called SPE-256. It allows the robot to track fast randomly moving objects and grasp them (movies here). The applications seem endless!
I have seen many robot mpegs as of late, many courtesy of /., but these have to be some of the coolest I have ever come across. A must see."
Here's the shameless Google Mirror
:-(
A human being recognizes external environment by using many kinds of sensory information. By integrating these information and making up lack of information for each other, a more reliable and multilateral recognition can be achieved. The purpose of Sensor Fusion Project is to realize new sensing architecture by integrating multi-sensor information and to develop hierarchical and decentralized architecture for recognizing human beings further. As a result, more reliable and multilateral information can be extracted, which can realize high level recognition mechanism.
Note that the site is mostly pictures, which explained why it went down so quickly. There's almost no decent text at all
I'm not Seth.
Got a look at two of the clips.
I would describe the speed as on the order of 1/3 the speed of a dog being teased with a tennis ball.
And the sequence looked about the same; the robot hand follows the ball back and forth just like a dog a then lunges out to grab it when it sees its opportunity.
Erm VLSI just means putting lots of stuff on one chip (Very Large Scale Integration). Do you mean "CMOS instead of CCD"?
(more detailed explanation)
The increased framerates possible using this technology, rather than CCD, probably help when doing fast motion detection as the robot in the article is doing.
This looked familiar - it's not so new, as it was on BoingBoing last October

But it's still quite amazing - that's why it stuck in my mind I s'pose
Well, I can think of two :)

i just put the movies over here as the site seems rather slow: PLEASE BE GENTLE PEOPLE!!!
The "eye" is really a high-speed sensor for a system of computers. The computers make calculations based on the fixed location of the camera and the variable, but known location of the robotic hand to determine the location in 3D space of the target. Then the target is stationary past a certain threshold time, the hand reaches out to grab it.
The computer array constantly updates the position of the arm and hand to try and match the location of the target, and that's where you get the illusion of human movement.
The human-like hand on the end of this arm is probably for the psychological benefit of investors, who would probably shit their pants at the sight of a high speed robotic claw grasping things dangled in front of it.

"On the gripping hand" :-)
I don't have much to add.
I tar'd all the mpegs into one file for easier downloading. Enjoy
None of us are as dumb as all of us.

The arm's we make are really quite amazing. Extremely fast, accurate, and articulate. They have a 4-degree of freedom (dof) arm. We also make a 7-dof arm that is absolutely mesmerizing to watch. (Steel aircraft cables are used to drive it).
