We are tying to design a working hand for demostration and future robot use. We hope to add an arm with all joints matching the human arm and hand. With matching controls along our arm we can extend our hands out to the robot and gain much more control of what we are picking up.

How much force can that hand squeeze?
We placed a empy pop can in it and in dented it and held it good. We may have to use the motors to hold items but it may heat up the motors.
