You aren't using an optical sensor or an accelerometer, and ultrasonic sensors would get too much interference from other robots.
My only other idea would be attaching a free-swinging pendulum to the robot. An encoder or Gyro attached to the axel of this device could then be used exactly the same as an accelerometer but without the noise. This does seem like a lot of work though. Does anyone else have a simpler solution to detecting speed?

Dude, that sounds WAY complicated. The trouble we're finding is that with the bumpiness (is that even a word?) of the surface, anytype of sensor like that creates (or created in our case as we stayed FAR away from it) a lot of noise. Never thought of a pendulum though, that would be kinda neat. But again, with the vibration I feel like the dampening system would need to be quite intense.
