NXT was the second generation of LEGO Mindstorms, released in July 2006 to replace the RCX of 1998. At its centre is the NXT Intelligent Brick, a small computer that runs the robot and takes signals from touch, light, sound and ultrasonic sensors, with three servo motors that can count their own turns. Robots are programmed on a computer with NXT-G, a drag-and-drop language built on LabVIEW from National Instruments, and the brick can talk to a phone or computer over Bluetooth.
