Ok the plan was to use the Makerbeam/Openbeam beams to make the frame work from Technobots. They can make a very good frame, easy to adjust and replace parts if needed, basically its a more advanced Meccano kit. But given the help I've had, I now have a body with the majority of components and I'll modify it slightly and fill in the missing components.

This is a good start for me and during my time using this build, I'll be adapting it and planning to build from the ground up. Don't intend to give away much else until I get the major stuff.
