//NOTE\\
*Verification of this information is pending...*

Team 303 used a what I guess would be considered a friction clutch on their 2005 robot. I am not sure on the specifics but it comes down to 2 gears and one engagement device on the same shaft. The gears and the engagement device (which is in between the two) do not have flat faces. The gears are sloped inward to a line that bisects the gear and the engagement device has two faces per side that slope outward from that bisecting line. Crudely demonstrated with text symbols it looks likes this:
__ . __
l / /\ \ l
l \ \/ / l


The gears' sloping faces have highly packed felt pads which stop the engagement device (laterally powered by pneumatics) from grinding on the gears' faces. It is a friendly version of dog shifting from what I can see of it.
For any more info contact someone from 303.
