pic: A more standard aproach

[Alex.Norton]

I'm using 8 motors in the drive for a couple of reasons. I like the idea of the extra maneuverability and control that is provided, i know that this is more complicated program wise but it is less complex mechanically and is lighter. Two motors weighs less than a chain tensioner plus chain and sprockets. Mechanically it is much easier cause I don't have to mount everything separately and all the pieces are the same and there are fewer of them.

The motors would be two Fischer Price and two BaneBots (don't know if we have all these next year so...). I'm pretty sure that the trans could handle the load because there is a bearing at the bottom that all upward force and most lateral force would go into. I would worry a little about the carrier plate but if the modules are well protected I don't think it would be a huge problem.

I got rid of the suspension cause of weight and the suspension is really complicated. I really liked the idea but it didn't seem needed for an actual first robot, plus this is much lighter and more importantly costs about half as much. The wheels cost $2.75 each instead of $100 each. And when I say "that which is shown" I forgot that I was only showing half of the bot. The entire thing, modules, motors, frame, everything weighs only 35 pounds. Of course with electronics this could be 10 pounds heavier but that still leaves much more than half the allowed weight to build on top of.

Orders... jee hadn't thought of that.
Thanks for the offer of help but I think I can handle it, however if I do need help. If you would like to CAD files just ask.

Thanks very much for all the input.
