Building a robot, complete beginner!



 I am a university student from Leeds, UK, and am wanting to build a robot to use
 in my coursework.

 It should be very simple I hope.

 I need it to function on a hinge, basically like an elbow. Ideally I would be
 able to alter the frequency/speed of the movements.

 It needs to be pretty robust and to withstand shock.

 Any ideas?

 Thank you for your help with this.
