Re: Implementing Traction Control for an advantage in the 2009 game

It seems almost criminal not to mention that it's possible to take values from the drop in electrical potential from one side of the motor fuse to the other. After applying a physical or code implemented low pass filter, the value returned is actually just a flat DC voltage that increases proportionally to the current drawn by the motor. A bit tricky to implement, but as far as being "poor man's traction control," at about $2 per motor or less it'd be a shame not to try.
