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?

Here's a hint; you don't need
any bearing at all on the robot's position, speed, or acceleration to prevent slipping. You don't need current sensors, either; just an encoder on each drive wheel.
I assume 2809 is probably doing what we're doing this year. More details to come on Monday (if it works).
