So, what about something that's not IR? But I guess this isn't the point...

I was thinking that you could use a ultrasonic device to send a pulse for the robot to listen for impulse during that pulse. That way it wouldn't get signals from other robots, and you wouldn't have to waste CPU time listening... Also, with ultrasonics, you can apply electronic filters on them, which means that you can choose to only accept your frequency.

Another thing I've read on some other posts is that you could use a gyro to make the IR detector always point toward the Robo-Coach. I suppose a electronic compass would work for that too (are we allowed to use those?)

Even though, I've been toying with the idea of not even using the hybrid part at all... That would make IR signals irrelevant...
