| | | Is there a way to stop the motor from exerting force on the gear rack once the steering has reached its furthest point? i.e. How do you stop the steering mechanism from going to far? (23 years ago, 27-Nov-01, to lugnet.technic)

| | | | | (...) Their are two methods I can think of. The first is the one I used on my Rotinoff. Simply use the large pulley wheels for your transmisson. Use elastic bands in the gear down mechanism and when the steering reaches the stop the small pulley (...) (23 years ago, 27-Nov-01, to lugnet.technic)

| | | | It had to be said: Use a rotation sensor and an RCX to interface to the motor A polarity switch will also work, see: (URL) (23 years ago, 28-Nov-01, to lugnet.technic)
