The NXT is a programmable robotics kit produced by Lego Mindstorms. It features a 32-bit main microprocessor and 8-bit microcontroller, input and output ports, an LCD screen, Bluetooth, speaker, and is powered by batteries. It can be programmed in many languages and uses sensors to read input and motors or servos for output. The NXT exposes concepts from an electronics class like flip-flops, AD/DA conversion, and microcontrollers. It aims to introduce children to programming, inspire creativity, and allow them to make simple helpful robots.
