Re: What motors do you use to drive your robot?
drill motors work fine and our team is using them again this year. It's crzy easy to do the drill motors simply because the mouting is prefabricated and the gearbox is something that has already been built. They're less of a drain overall on resources to use. Problems with the drill motors can be heat, our motors had major problems with heat because we ran one forward, one in reverse and the drill motor is not designed to go in reverse for any long periods of time. In time, one of our motors literally cooked, the back melting into a big mess of plastic and wires and all that. Heatisnks have been used before the cool the motors as have fans, though that does some to cool the motors, heatsinking is better.
The problem however with the Atwoods (the CIMS you were talkign about) is that there were not designed to run for long periods of time according to one of our mentors. They lack a cooling system, fans or even vents, for that reason. So when you run them, all the heat builds up insides of the motor and you end up setting yourself up for major problems. The other issue of gearing down is a valid one because a gear box (and a good one at that) is needed so that the drive train will not kill it self when it tries to inch forward...they spin I think at like 5000rpms or something like that when you hook them up to a battery. So you WOULD have to gear down the atwoods...and if the gear box isn't build lacking completely of movement, gears start seperating and thus, start stripping. It can be very bad.
All in all...stick with the drill motors. They're convenient and lack a lot of the problems that the Atwoods have.
