I haven't had the same poblems, but I have a theory as to your problem.
There are two probabilities:
1) The motor is causing too much noise and is interfering with the
sonar, or
2)The motor is giving off electrical noise (i.e. electromagnetic waves)
which are interfering with the circuitry.

| Hi, I have some motor trouble. I have two motors. I have a polaroid sonar. When I run one of the motors, the sonar works. When I run the other motor, the sonar's detected distance jumps arround randomly. The randomness seems to be more at higher (...) (30 years ago, 19-Apr-97, to lugnet.robotics.handyboard)
