Lego Mindstorms NXT Kit and Add-ons.
The Lego Mindstorms NXT is a programmable robotics kit released by Lego in late July 2006. It replaces the first-generation Lego Mindstorms kit, which was called the Robotics Invention System. The base kit ships in two versions: the Retail Version (set #8527) and the Education Base Set (set #9797). These can be used to compete in FIRST Lego League competitions. It comes with the NXT-G programming software, but a variety of unofficial languages exist, such as NXC, NBC, leJOS NXJ, and RobotC. A new version of the set, the new Lego Mindstorms NXT 2.0, was announced in January 2009, featuring an advanced color sensor and other upgraded capabilities. This set is available in the UK, German, U.S and Australian Online Lego shop. The NXT 2.0 sets was officially released on August 1, 2009, and its official product number is 8547.
The main component in the kit is a brick-shaped computer called the NXT Intelligent Brick. It can take input from up to four sensors and control up to three motors, via RJ12 cables, very similar to but incompatible with RJ11 phone cords. The brick has a 100×64 pixel monochrome LCD display and four buttons that can be used to navigate a user interface using hierarchical menus. It also has a speaker and can play sound files at sampling rates up to 8 kHz. Power is supplied by 6 AA (1.5 V each) batteries in the consumer version of the kit and by a Li-Ion rechargeable battery and charger in the educational version. The Intelligent Brick remains unchanged with version NXT 2.0. There is, however, a black version of the brick which has been made to celebrate the 10th anniversary of The Mindstorms System.

For all your NXT Mindstorms Advanced Sensors & Accessories visit Mindsensors, Hitechnic, MicroInfinity & Dexter Industries.
Mindsensors, although not fully supported by Lego, produce Excellent Quality Sensors, Multiplexers and other Accessories for the Mindstorms NXT. I've been purchasing their sensors for nearly 10 years, starting with a Compass Sensor for my RCX set. The sensors Mindsensors sell are very well made and I've yet to have one fail. They provide excellent service and after sales support.
Hitechnic are fully supported by Lego, produce Excellent Quality Sensors which are cased the same as the original Lego produced Sensors. My only complaint is the excessive postage charges they employ in comparison with Mindsensors. I've purchased sensors from both companies on the same day, but having a $25.00 cost for P&P difference. The Mindsensors parcel arrived here in Tasmania a whole week earlier, despite the price for P&P difference.
