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)

Awesome! Thanks for building one of these. Have you put together any instructions or a .dat file? I'd like to use this in a 4x4 I'm building. Thanks again. -Nathan (...) (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)

(...) 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)

(...) One thing I noticed about Technic Axles is that they seem to have a bit of rational flex. You have to have something with a bit of mass being rotated about the axle to notice it. Look at my znap/technic ferris wheel here ... (URL) The center (...) (23 years ago, 27-Nov-01, to lugnet.technic)

(...) Definitely. Although it doesn't need to rotate much, I've used such an idea on my bridge (URL) for the main support hinges. Also, as it only takes forces in 1 direction, I've only used 2 corner (macaroni) pieces on one side. The sections of (...) (23 years ago, 27-Nov-01, to lugnet.technic)

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)

(...) Probably, but I think an easier solution is to have multiple shearing planes on your axle (a normal Technic axle). You can kind of see this idea in my crane: (URL) don't know how much shear force an axle can take, but I know it's quite a bit. (...) (23 years ago, 27-Nov-01, to lugnet.technic)

Hello, When I see those very big cranes, I wonder how the pivoting points at the bottom of the large booms can hold it out. Are two or more beams with a technic axle enough to handle the enormous force ? I was wondering if it's possible to build (...) (23 years ago, 27-Nov-01, to lugnet.technic)
