In response to the above posts:

artic_raven: Cut one of these in half and you have a VERY easy to machine 2 speed transmission, not to mention tiny and light.

DeepWater and cabbagekid2: I have no idea if Jim intends on posting a software whitepaper, and if so, when.

1028_Machinist: There is no wheel speed sensor. If you look at the whitepaper, the output speed is measured by a shaft encoder. That is what the automation uses. If you knock that loose, I don't think you'd have to worry about driving around in any gear....I don't think you'd be driving around at all. You can put a manual override if you want, though.

Nitroxextreme: Wheel speed sensor would be a banner sensor (light sensor) aimed at a tone wheel. A tone wheel is basically just white and black stripes, and the banner sensor reads how fast the wheel is going by "seeing" the change between white and black as the wheel rotates. In our design, there is no wheel speed sensor, just a shaft encoder which reads how fast the output shaft of the transmission is spinning. There is no sensor built into the motor.
