This may be more appropriate for lugnet.technic. There has been postings or listings of these before, but don't let that stop you. You should add the turntable gears (outside is 56t, I think) somehow. I also would rather see the vertical in mixed (...) (25 years ago, 6-Nov-00, to lugnet.robotics)

| | Gear spacings.

I've never seen a table of allowed spacings between gear wheels. (For example, two 40t gears will mesh nicely if spaced apart by three studs horizontally and 3 and one-third bricks vertically). I wrote a little program to compute all possible (...) (25 years ago, 6-Nov-00, to lugnet.robotics)

Hi Robert, (...) thanks for the pictures. One may call your design a bit untraditional and questionable, but on the other side it is a pragmatic and fairly compact solution. I tried to construct a drive made of a single tire meshed with the focus (...) (25 years ago, 6-Nov-00, to lugnet.robotics)
