Or a mechanism which keeps the gears on a intermediate shaft running
so as to allow the gears to mesh when shifting. A faq of the LEGO
robotic terms might help clear some of these terms up ;-)
One of the problems encountered with most of our LEGO designs it the
trade off between power, speed and accuracy. Using mode than one motor
to provide power to individual wheels can lead to the robot not
following a straight path. Where as one motor may not have the power
to supply all of the motive force for the robot.
I'm toying with a design which would allow slaving more than one motor
off a output and additionally providing power from a seperate battery
pack. My current design would require an external circuit to drive the
motors so it's not a solution that could be applied by everone.

| (...) Hi, I'm new here, so if I'm missing something, sorry! Seems what you are describing is just what I'd call a "relay switch". The output signal from the RCX goes to a switch, which switches the external power going to your motors. Seems to me (...) (26 years ago, 14-Jan-99, to lugnet.robotics)
