Steve,
One rotation sensor is allowed. There are also two light sensors,
so your idea is definitely doable.
The situations that are confusing are when the pull of the other
robot prevents your robot from making any headway, as well as when
your robot is actually being pulled back. Are you suggesting that in
these situations it would be better if the wheels are stationary and
locked as opposed to slipping as they keep spinning ? My physics is
is definitely not up to this task - lol.

| You only need one rotation sensor and some fancy gearing. Using a differential in a way similar to the "South Facing Cart" or the stearing drive in a dual differential setup, you could directly measure the amount of spin between a driven wheel and (...)
