So, My team, has in the past, made a fully custom frame out of T-Slot and 1" Square tubing, with supershifters, and tank treads. This ends up quite heavy, taking up a significant amount of our weight budget.
So, I was looking into doing a
Kitbot on Steroids style frame, with some modifications. How much will this end up weighing, about? Both including gearboxes, and excluding them.
The other thing we were looking at was the
NanoTubes frame. It seems to have a multitude of problems (center wheel not driven)
Whats the weight situation with these? Any teams with experience of these?
What do you guys think? Any other easy to use/build drive systems available?
I didn't say it bad English, though. Grammatically, it's perfectly proper. - Greg Ross [more]
