Post subject:  Motor stall control


Has anyone succesfully built a stall control function on NXTmotors? Any advise in this direction?

My motors are PID controlled. I am trying to built a stall control mechanism using the motorPWMLevel function. I believe this function returns the amount of power sent to the motor. I'm hoping that the ratio between motor power and motor speed gives me some clue about the stall condition of the motor. But other factor might also affect the power to speed ratio, like acceleration for example.

So please give me suggestions, experiences and so on.
