Actually, I am not convinced it means gears. One of the switches could be
mounted with a 45 degree tilt. This would remove the issue of play in the
gears.
You could also link the handle holes of the polarity switches with a solid piece
(as opposed to a single linking axel through the axel holes). You should be
able to get a 45 degree tilt this way also.
And, can I have a gorilla mascot too? :)

| (...) Linking via the handles would cause problems. First, there is a great deal of friction added to the system when an axle is in that hole. Second, I think the proposed method requires the switches to continue rotating the same direction. Steve (21 years ago, 23-Aug-05, to lugnet.robotics)
