4 DOF T-HEX Leg Assembly Instructions.

Updated 11/11/2010

Safety first! Wear eye protection and never touch a powered robot!

Important! If you are building legs for the T-HEX robot, you will need to build three right legs (following the pictures on the right), and three left legs (by following the pictures on the left)! If you are building legs for your own creation, you can choose your own style.
