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, you need to build three right legs and three left legs. This is also true for a standard insect-looking hexapod such as the EH3. However, if you are building for the EH3-R using the ServoPod, you need to make 6 right legs.
