Upper-torso Robot Circuit

Hi! I'm an Electronics Engineering student and a newbie in Robotics. We are about to make a pick and place upper-torso robot. I don't know how to make the circuits needed to make the robot work. Maybe you could help me get the circuit diagrams and the list of components needed. Thanks a lot!

You're going to have to be much more specific about what you're doing. Upper-torso robot circuit is as vague as saying we are building a computer circuit.
