Agreed!

I looked at moving them to the diagonals, too. I'd be worried about slippage in high-torque situations. 16-tooth gear seems pretty stable already. What about putting another #2 axle connector opposite the first one without fastening it to anything else? It would help with stability in one direction, and the worm gears hold it in the other.

| I'm not sure I follow you here. Even though the 16-tooth gear doesn't mesh as deeply, it seems to be sufficient to prevent slippage. There is a little more slop, however. Note that in my suggestion to move the worm gear shaft to the diagonal, I may (...) (23 years ago, 8-Sep-01, to lugnet.robotics)
