If a motor stalls, it draws a lot of current (compared to normal operation).
You can measure that quite easilyusing dedicated chip, or by measuring the
voltage over a small resistor in series with the motor: if more current is
draw, the voltage drop over the resistor will increase. You will however
lose a little voltage also when the motor is not stalled.

Ps. does anybody know where to get the Polaroid 6500 sonar thing in Holland?

| Hi all, I'm working on a dead reckoning 'bot. I'm not really interested in what the wheels are doing unless they're stalled. Anyone know any good tricks for monitoring the motor current, or should I go with shaft encoders anyway? Thanks! Paul (25 years ago, 27-Oct-99, to lugnet.robotics.handyboard)
