I was wondering what potential ways there are to control the actuation of a mechanical hand by using one's real hand. With the design and prototype (so far) that I have, I've used a single-cable mechanical setup where a single servo controls the flexion/extension of the finger by pulling on the cable.
Essentially what I need is for the servo rotation to be controlled by a user's finger movement (i.e. finger movement downwards or upwards will cause the servo to spin in opposite directions, causing the mechanical finger movement to be an imitation of the user's real finger movement).
What type of system do you think would be the most appropriate to implement? One idea I had was some type of motion capture system, where sensor readings or even finger positioning in space could be translated for the servo to spin. And would Arduino be an applicable platform to do this, as for example with the mocap-type system I just mentioned, it would need to use camera feedback and I don't think Arduino can support this. I'm fairly new to controller systems, so any help/ideas passed around would be great.
Maybe the community will be able to generate some cool concepts!
