Mini Alpha: A robot arm made with LEGO Mindstorms EV3

In this model, all three motors are concentred in the base, and the movement is transmited mechanically to the joints.This allows the superstructure to be light, fast and quite compact.

Despite having only two degrees of freedom, it has a great motion range that allows it to move lego balls quite efficiently.
