Ive tried counting the sharpa hand’s DoFs but cant get to 22 - am I blind?
@_mattfreed I'm trying to wrap my head around how high the McMaster markup will be on this...
If it can't move and perform meaningful tasks like a hand it doesn't matter how they count DoFs anyway. You can have 16 DoFs or 22 but it comes down to actuator precision, grip control, joint overheating, and even the whole software parts. Surely they want a high DoF to put on those sheets but all that really matters is a live demo.
@_mattfreed Backwards and forwards
@_mattfreed 4 each finger, pinky has 5, 1 for wrist? 4x4 + 5 +1??
@_mattfreed My guess based on this image: Each finger has three curl joints plus 1 splay joint where it joins the hand(16). Pinky and thumb adduction/abduction (2). Thumb rotation (1) Thumb curl (3) =22 total
@_mattfreed I get close. I think a lot of the fingers “wag” as well as their intuitive function.
@_mattfreed you missed these DOFs - how hot the hand has become - how many digits are broken at a given time - wrist joint, because marketing
@_mattfreed IF the fingers can splay (like my human hand) and there are 2 rather than 1 joint in the thumb, I get 4x16 for the fingers, 4 for the thumb (which appears to have 1 more joint than my thumbs) + 1 for the wrist I get to 21. I've not seen the device so cannot confirm any of this.
