I decided that MK 1 robot was a little poor so I went on to do a MK2 before finishing MK 1 ( it just wasn't a design worth continuing), this is still a work in progress but its a far better design than the original (MK1).
I design robotic systems all the time in 3D CAD, MK1 wasn't done in this way, MK2 is.
Concept done on Solidworks 3D CAD

This design recycles all the bought out components of the MK1 robot including the flange bearings, axles, motors, batteries, sprockets, and wheels.
This Solidworks CAD picture is still an on-going design, the two main chassis plates that the flange bearings are bolted to have been cut to size, had the holes added. The flange bearings have been bolted on, axles through but at the moment that is as far as it has got, I'm awaiting machining of a extra set of bearings, round chassis bar, two sprockets and wheel hub plates.
The main area of further design is the mounting and mechanical movement of a camera, I intend to mount a camera within the front end of the robot, this camera will then be mounted to a scissor jack or hinged arm to lift the camera roughly 300 - 400mm.
