I have most of the inside structure worked out now. The four uprights will be supported at the top by some removable clamps. This will allow me to slide on additional supports for the CPU module and anything else that needs adding. These clamps are yet to be designed as I want to assembly the central part of the robot first. All the motor parts have been assembled and I have used some parts salvaged from an old printer, this includes a couple of brass bushes. Next steps are to test a stepper motor I have from the same printer to see if it has the required toque to steer the drive wheel. I have dug out an arduino mega for quickly creating some code on.
