How to make a robot hand without using servo motors?
Objectives of the hand :
-Should be able to handle it's own weight
-Should be able to grab small weights 1grams to 5grams.
I'm planning to make the hand using only e-waste and this is the second reason I'm not using servo motors. (I'm from south Asia, there for it's hard to find servo motors in the e-waste.)
Can someone give me an advice or can someone tell me is it possible to make a robot hand without using any servo motors?
