This would be very, very cool. Especially if we can start to get "Star
Wars" style beeps and clicks, and get them to mean something to the
bots.

Hehe - that could actually work well, and look quite interesting - if
I remember correctly, R2 units in star wars seemed to use some kind of
rotary communication system, and beeps/whistles - thats your return
path sorted.

If I remember - doesnt the Cybermaster have very basic odometry in the
motor/wheel outlets? Which would put it not quite on par with the NXT
servo style, but might help here.
This idea really grows on me.

| (...) Well, RCXs have been interconnected via input and output ports (or even input to input ports), so I think it's likely. But if we have Bluetooth (faster, more secure, doesn't require a physical connection, and address multiple objects), why not (...) (18 years ago, 11-Jan-06, to lugnet.robotics)
