I have found alot of small motors and gearboxes and alot of large expensive motors and gearboxes.
The small controllers ($15) only do like 2 amps and the large controllers are like $300 the small motors are a $10-20 and the large ones $160 with gearbox.
So im stuck with $30 or a $460 drive system, i need something in the middle.
My robot will be relativly heavy (100lbs) but no need for speed, an inch or two a second will be enough. I do need accurate stearing, as my arm will have no rotation, instead rotate using the entire robot.
I would really prefer a tracked system, but i dont see any of those either.
So if you have any good links, please share them :-)
