Ok so you may do this via Bluetooth but that is the only way i could possibly think of doing it unless you could get a cord like an a to a cord but with the trapezoid USB cord. Sorry i wish i could help more and why are you trying to do this?

BT and RS485 are the only two methods that don't rely on some other form of processor or other IC(s).

If you use USB, you need to use a computer between them, as an NXT can't be a USB host. The same goes with I2C, you would have to use a uC between NXT's, as an NXT can't be an I2C slave.

Bluetooth on the NXT can be master or slave (maybe also peer-peer), so you don't need anything between NXTs to use it. RS485 is peer-peer, and can be programmed as master-slave, so it could also be used directly between NXTs.

He used the NXTBee (http://dexterindustries.com/NXTBee1.html ), but I'm not very experienced with that. This is his blog: http://www.ericsmalls.com/ . You could try asking him about it by leaving a comment on one of his projects; he has a lot more experience with this than I do.

Hi guys,

This topic deals with multi-robot communication.
Dexter Industries NXTBee utilizes Xbee radios and the NXT's high-speed RS-485 link (sensor port 4) to accomplish multi-robot communication. I've done a number of projects in this area.

If you're interested in learning more visit the following links.

If you have any more questions post them in the ROBOT-C multi-robot forum:

Thanks!
