I've committed to a Robomagellan 'bot for next April.
Early work on Ebay has netted me the wheels and suspension parts I was after. Traxxas E-Maxx parts.
Lower chassis plate is fiberglass, the next two decks (below and above the fiberglass bulkheads) will also be of 1/8" stock.
Into each of the grey bulkheads will go a machined round aluminum plate to take a ball bearing race. There will be two motors each driving the three wheels on its side via 1/5" pitch timing belts and pulleys. a series of six drill-rod shafts will drive the CV joints to the wheels. The opposite ends of the shafts will be supported by bearing blocks.
A 15 A RoboClaw will drive the motors from a 24 V battery.
More on electronics later.
We need to expand the heading from:
"2WD, 4WD, Carpet Rover, and other rover robots."
"2WD, 6WD, Carpet Rover, and other rover robots."
