for this assignment I have to design all the mechanics form my final project.

My final project is a modular reconfigurable robot consisting in three homogeneous modules, that means that I have to design one module and the others will be the same.

the basic idea for a module is to put two servo motors together in opposite directions and place two "side-cases" in their shafts.

The basic mechanical components are shown bellow:

Basic components of the robot

The complete design of one module and its assembly is shown in the following pictures:

The magnets and screws shown in the pictures above allow to plug the modules each other with 0 or 90 degrees phase.

At the same time the magnetic joint allow the electronical connection and the signals pass through the magnets and screws.

I used 3D printing for most parts of the robot, "side cases", lower lid with fake shaft, servo brackets, nuts holder.

to keep the two servo motors together I designed and printed a "double lower lid with fake shaft" replacement.

for the elctrónical connection I welded wires to nuts which will be in contact with the magnets and then printed a piece to keep the nuts well positioned

fFinaly the first test...
