6 DOF Robot arm

This is a robot arm with 6 degrees of freedom. The design challenge was to get such a heavy design implemented. The torques are quite high, but it works well.

I used two Lego micromotors in the hand, for wrist and gripper motions. Unfortunately, these great little motors are now hard to get -- try the Service packs in Shop-at-Home and you may get lucky.
