I designed mine using CAD, planning out the locations of all the parts carefully. This is the most important step to making a robot!
The wheels are servo driven, the material is made out of HDPE and bronze metal sheets, the back wheels are foam, and in the front is an orange caster wheel.
I hand made each of the components using a manual mill.
Follow the images in order for construction steps.
