Glad to see this get brought back up.

Each gearbox has a vertical CIM motor with a worm on the end. It turns a spur gear that is connected to the output axle that the wheel is mounted on. The whole gearbox sits in a UHMW block that we added grooves to for cables to run through.

The UHMW blocks sit on a 1/4" thick aluminum plate attached to the frame. Each of these blocks are tied together using cable that is wound around another UHMW pully that is connected to the window motor.

When the window motor turns, so do the gearboxes. Here are some links to more pictures of this drive.
