The feedback concept has to be developed some more to get real results.
There have been a few ideas but I have yet to hear of any of them being
implemented. Look at the list archive (sorry cant remember the egroups
address) for some ideas. Feedback resistors at the motor driver, I believe,
yielded more feedback.
