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)

Two ways I can think of: 1) use one of the white clutch gears 2) us a mindstorms rotation sensor to count the number of turns Tom (...) (23 years ago, 28-Nov-01, to lugnet.technic)

The simplest way is to merely use a clutch gear. (URL) The motor will continue to spin, but will quit pushing on the rack, effectively keeping your assembly in one piece. -Nathan (...) (23 years ago, 28-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)

(...) [snipped] (...) That pulley method immediately reminded me of a long since past Technic set that used it for motorized steering: (URL) be smaller thanks to the red mirco motor. (I sure don't recall one in 1980!) Adrian Egli (23 years ago, 28-Nov-01, to lugnet.technic)

Set 8082 - motorized buildign set included both a micromotor and a car with mircromotorized wheel and rack steering. The motor is simply too slow and powerless to steer in any reasonable time. The mechanism also used rubber bands (URL) (23 years ago, 28-Nov-01, to lugnet.technic)
