As has been posted, you can use current draw, but I wouldn't use the sensors that came with the bot. They are extremely inaccurate and fluctuate constantly. If you really do want to take this approach, I would suggest looking for a third party supplier for a decent current sensor.
[EDIT] You could also use a condenser(I think thats what the potentiometers that can spin all the way around over and over all called) and just poll in your programming whenever they loop back to zero.
