I completed the first version of the 3D CAD for W.A.L.T.E.R. 3.0! Four custom decks is what makes him what he will be. The top and bottom decks are fixed in place, but the two middle decks can slide up and down on the (0.5" OD) aluminum tubing pylons. This will allow maximum flexibility to build whatever configuration I need at the time. The rest of the parts I will be using are from the Actobotics line by ServoCity [servocity.com].
