It's just an ordinary motor after you modify it to take out the feedback device,
and you have no idea of where it is pointing at any time. Maybe you could have
the robot turn in a circle to find the beacon? Or use a small stepper motor? You
can drive a bipolar stepper right off one of the L293D motor ports. If you don't
like either of those ideas, how about mounting two servo motors, one on top of the
other, with your sensors on top of the two. That way you can get nearly 360° of
rotation.
Good luck!

| (...) Hi all, why so complicated ? Use a pair of gears to double the turn ability. We had the same problem (to find a beacon) and succesfully build it. I guess you don't have to be 1 degree accurate, or ?? I think 2 degrees will work. (You don't (...) (23 years ago, 16-Jan-01, to lugnet.robotics.handyboard)
