Re: pic: 971 Friction Clutch Transmission Insides

Something (semi) interesting to note, we did some extra testing of this drum transmission today at 254's lab. When we removed all air pressure, and ran the robot against the wall, we could slip the tires without slipping the clutch. There seemed to be more enough friction in the clutch, even without normal force from the piston, for the clutch to remain fully engaged.

Further testing at low but non-zero air pressures failed because... I broke their robot removing the breaker from the compressor spike.
