Lego has changed a lot since I was a kid. The Mindstorms NXT kit comes complete with a 32-bit microprocessor, 3 interactive servo motors, a sound sensor, an ultrasonic visual sensor, an improved touch sensor, and an improved light sensor. Throw in another 519 pieces, 4 input ports, 3 output ports and 7 6-wire cords Matrix display, Piezo speakers, USB 2.0 and Bluetooth support and the ability to program your creation and you can come up with some pretty interesting robots.
Lego has now announced that the firmware behind the MindStorms microprocessor will be released as open source. They will also release software, hardware and bluetooth developer kits
The firmware and developer kits will be made available in August 2006.
Soon you will be abel to use your Windows Mobile device to control your army of robots!
