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 PC’s.
Using components available from the NXT kit (and also creative additions if you like), all you need to do is 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.
