Rick Brooks wrote:So, when you load the motor down, the rpms drop and it draws more current. The armature resistance doesn't change with load.

Colin wrote:That looks interesting, was just thinking "not much of the motor in the clamp" when I realised you've got them mounted inside a split tube... it would be good to have the screw mounting to the chassis spaced as far apart as possible to give better resistance to the torque. Have you given consideration to the twist (horizontal plain) when you reverse the motor direction?
Colin wrote:I think it's always the case that hobbyists improve their skills, I get the impression that most people don't stick around minisumo that long, they head to more interesting projects rather than put the effort into the competition - a passing interest, that's mostly filled by off the shelf kits
