The Lego Mindstorms NXT system is a computing brick featuring a 32-bit autonomous Lego processor that can be programmed via PC or Mac (which is a first). The programs designed on the computer can then be transferred to the NXT Intelligent Brick through a high speed USB 2.0 cable or by using the brand new Bluetooth wireless feature. This Bluetooth technology makes it possible to control the NXT Brick wirelessly by means of a PDA, cell phone, laptop and more.
Not only has the Intelligent Brick been redesigned but the sensors and motors have been revamped as well. Here is a quick list of what has been changed and added:
- 3 interactive servo motors feature inbuilt rotation sensors to align speed for precise control
- New ultrasonic sensor makes robots "“see" by responding to movement
- New sound sensor enables robots to react to sound commands, including sound pattern and tone recognition
- Improved light sensor detects different colors and light intensity
- Improved touch sensor reacts to touch or release and allows robots to feel
- 519 hand-selected, stylized elements from the LEGO TECHNIC® building system ensure robot creations will be sturdy and durable while also looking authentic
- Opportunities for physical programming of robots and interaction with robots during programming
- 18 building challenges with clear, step-by-step instructions help acclimate users to the new system to create robots ranging from humanoids and machinery to animals and vehicles
- Digital wire interface allows for third-party developments
