The first open source crab robot. 18DOF.

6DOF motion control system. I want to make one large enough to sit on and pair it with some Occulus Rift goggles.
3- and 4-armed motion control systems for pick & place.
Before you build a 3d printer, build this open source design and learn the basics of motion control.
