Re: Direct Drive Four Motor System
On a similar topic, our six wheel "direct" drive originally started out as a 4 motor/ 4 wheel design, which we then expanded to six wheels, and used driveline to connect all of the wheels. Upside, no chin/belts/tensioning . . . Downside? Weight, it was fairly heavy, but it worked well, and we were able to add encodes to get a good idea of where we were. Not quite as modular as a moter per wheel design, but we did it with just the 4 cims, and it did work quite well.
I would strongly encourage teams to try out more designs which use direct/line drives instead of chain/belt.
P.S. here is a picture of the front 4 wheels of our system: http://www.chiefdelphi.com/forums/sh...highlight=1097
