How hard do you think it would be to put some gearing on the back wheel?

just a bit harder than a friction drive.. actually, i think cutting the rear end off completely and rebuidling a whole new rear end with a gearbox would be easier than attempting to squeeze somthing into what is already made compact........
hey! how about some 4 speed gearboxes!! with a clutch, of course so you can really rev it and drop the clutch to burn some rubber..... or in this case, the tires arent rubber are they? well, then.. we need to get black rubber tires so the janitors can yell at us for putting too many rubber marks in the hallways!

GreenCactus:Genius!

This is an excellent way to get some offseason practice in the fabrication of transmissions!

w00t!

It's got everything going for it:

• It's Cool
• It's an accurate simulation of the stresses endured by a robots gearbox. (A bit tougher I suppose...)
• It's fairly easy
• It's cheap

So now my project is to make one of these with a four speed. A truly cool thing to do would be do make shifting automatic...
