Aiko V2 New Designed

Hi,

Took me many hours of non-sleep to finish the most natural movement robotic hand.
Designed and print from 3d printers.
It takes about 3 hours to print one finger, the hand took about 3 days to print.

The finger can do abduction, adduction, flex and extention.
Even the palm can move too.
Pinky and thumb movement is almost like human.
From posing peace sign, “OK sign” and even make a fist too.
The thumb can touch all fingers.
Weight about 500g.

Designed to work with 28 Flexinol Wire muscles (try with flexionl wire… work OK)
or
14 servo
I probably going to try both to see which is better.

Very nice print. The design looks really nice and robust.
Are you making these available?

Cable control would work fin for this… you may like to take a look at my cable control systems. they may give you an idea for how to do yours:

Very nice!

How small can the servos be? What’s the torque requirement?

Like we were discussing Jonny!

Right now I am fine tuning the pinky and the thumb.

There are 3 options to control the fingers.

  1. flex wire muscle … which is less accuracy… no motor … no noise.
  2. servo will be mount in the lower arms… Accuracy… motor … noise.
  3. small dc gear motor with encoder… accuracy,…motor …noise and expensive.

Next week I will start on the wrist and lower arm…
everything must be human size and anatomic correct… so more harder to do.
