Yep. I'm not at all sure about hardwiring two NXT's together - to be honest,
I've not even thought about it, because BT connections are so easy and secure.
Early on I investigated the BT option by sending simple numbers between two
NXT's. But there are other options: Steve H made a remote control, and I
recently made another one (time for some NXT racing!). And since communication
can go two ways, the "vehicle" can send detailed information to the remote for
display etc.

Well, you could certainly use a motor to turn a disk, and a light sensor on a
second NXT to read the color of the disk... or the position. Mechanically
linking two NXT motors together would certainly work, and allow the sneding of a
nearly unlimited number of messages... but why bother when BT is sitting there,
just waiting to be used in lots of neat ways?

| Hi all you M[U|D]Ps I know most of the MDPs probably only have 1 NXT, but I'm hoping someone out there has 2, and has investigated NXT-NXT communication. Is it possible? How hard is it? I'm currently thinking Bluetooth, but is there any other way? (...) (20 years ago, 2-May-06, to lugnet.robotics)
