Hello,
Some info
that may be of interest: The Bluetooth Special Interest Group has launched a
competition for fans to design a robot from the Lego Mindstorms NXT kit that
uses Bluetooth technology to connect to other devices like mobile phones or
PCs.
Using components
available from the NXT kit (and creative additions if you like), just capture
your robot on video with its Bluetooth capabilities in action. The most
impressive entry wins the competition, which has cool Bluetooth products for
prizes.

Have fun!
