I am looking to build my first bot, can somebody answer the following please.
1) Am I better off going for 500rpm 7.2 drill motors or 14.4.
2) What amp controllers will I need for these.
3) As the drills themselves are 0-500 rpm could I not use the controller thats built into the drill.
4) What size wheels are the best for an invertable bot Thanks
1) 14.4v
2) I would say something around the 20amp plus mark to make sure they dont burn out
3) No as it wont interface with any radio control gear and even if it did it is cheap and nasty.
4) depends on how tall you want your robot to be but if you are bolting the wheels onto the drills then I wouldnt go much larger than 150mm in diameter max.
If youre looking for a near-complete starter pack including drills, wheels, controller etc. then look no further than this offering of mine: http://www.gimsonrobotics.com/shop_robot-kits.htmlhttp://www.gimsonrobotics.com/shop_robot-kits.html
All the best, Ewan
Over here in Belgium and the Netherlands we have the MSR drivetrains.
very powerfull, compact, easy to use and not that expensive.

Have you got a link for that Mario?
i might be interested too mario
It seems the builder has discontinued the MSR drives.
By lack of the cheap, but powerfull motor simular to the 6 times more expensive (but still not too expensive) speed 900 BB Torque motor.
couldnt find a thread so i stuck it here.
