3 DOF Leg Assembly Instructions.

Updated 08/30/2007.

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

Note: Do not use Loctite or thread locks on the assembly. They are not necessary and may cause damage to the Lexan.

Important! If you are building legs for the EH3-R using the Bot Board / Basic Atom 28, and SSC-32, then you need to build three right legs and three left legs. This is also true if you are building for a standard insect looking hexapod such as the EH3. However, if you are building for the EH3-R using the ServoPod then you need to make 6 right legs.
