This post is very late but has to be made. Beat's crane is incredible! Not only is it big but the aesthetic detailing is outstanding! Truck cranes are hard to design. Is there a video of it working? -Nathan (18 years ago, 24-Mar-07, to lugnet.technic)

Alexander, Thanks for the differential/pole-reverser idea. Based on your description, I was able to get a prototype running very rapidly! I'm still seeking a clean more mechanical version, but this certainly will work for now. Along the lines of a (...) (18 years ago, 23-Mar-07, to lugnet.technic, lugnet.robotics)

OK - for all the mechanical gurus here... You've probably seen my RC manas truck on the sidebar here. The steering is controlled by one manas motor, geared down so it's really slow. This is done so that I can get the wheels back to center, because (...) (18 years ago, 23-Mar-07, to lugnet.technic)

Hi Mark, Nicely done, and welcome to the never ending fun of the GBC!

I think one way to do this uses a differential (URL) and a pole reverser (URL). I don't have a picture to hand but the idea is simple. One side of the differential is connected to the low torque "input axle". The differential housing is connected to (...) (18 years ago, 21-Mar-07, to lugnet.technic, lugnet.robotics)

More information about your application would be helpful. The first thought that jumps to mind is "Use a more powerful motor. Duh!". So there must be something that I am missing. There must be some reason you need to use the puny motor. Maybe you (...) (18 years ago, 20-Mar-07, to lugnet.technic, lugnet.robotics)
