Title: Hand Robot Android Mechanical limb
Post by: Ai-bot on 08/08/2008 20:47:06

Hi

Here is Aiko's new prototype Hand.



Pro:
1) 5 movable fingers
2) Compact size. Same as human's hand
3) Will have complete sensors for feedback
4) Low Power consumption 5V
5) Can be use for Aiko.
6) 15 movable joints
7) Material Cost $1800







Can be use for Aiko or for human. Life-like mechanical limb that has the ability to feel physical sensation.
(Control by human muscle) special senors and controller will attach to the human's muscle. In other words, controlling the hand with our muscles.

Human Brain >> Nerve Impluse >> Muscle >> Aiko's Hand

This technology can be beneficial for people born with or who have undergone amputations.

Since, I can't find any volunteers, I guess I will test it on myself.


About 6 minutes of video

Very interesting, thanks at-bot

I wonder how strong it is as the real hand is very strong?

Regards

Alan

Very cool video.. has some ways to go but really offers a lot more..as far as grasp! If they could give it a skin like cover that is still as sensitive to touch that would be so cool!

I hope you can find volunteers. It would be interesting to see if the brain control function is as good in long term amputees.

What do you think?

Hi

The current max it can carry is the size of an apple.
It was a prototype hand with 5 movable fingers.

It was hard controlling the hand with the muscle, but I get use to it.

I am currently making the hand smaller for Aiko to use.

The new hand is smaller, but with more torque.

This is aiko right hand version 2.

Here is the new spec for the new hand.

1) Weight only 95g which is 1/3 of the weight of the old hand.
2) 2.5x more power and more torque.
3) 35% smaller than the old hand.
4) The fingers are small enough that it can type on a keyboard.
5) The palm of the hand is cable of bending. If add additional servo.

The glove you see is woman wedding gloves small size (s).
I was shopping in Japan a few months ago, it was nice so I bought it.
I mold the new hand from that gloves.

I will do a demo with the new hands in a few days.. thinking of McDonald or Wendy.
