LEGOMINDSTORMS NXT 2.0 is a perfect Christmas gift because it teaches your child to think and explore. It's fun for adults as well. Everyone can join in!
First, the brain of the MINDSTORMS robot is NXT, an intelligent, computer-controlled LEGO brick that features a 32-bit microprocessor, a large matrix display, input and output ports, and a speaker.
Second, three Interactive Servo Motors give you precise control over the robot and ensure that the robot moves with precision -- the built-in rotation sensor can measure one-degree steps.
Third, there are four robotic sensors. The first is the Ultrasonic Sensor, one of two sensors that gives your robot vision. You can use it to make your robot avoid obstacles, sense and measure distance, and detect movement.
And fourth of all, two Touch Sensors give your robot a sense of touch. They detect when they are being pressed or released, and you can use them to make your robot pick up things or act on command. For example, by pressing a Touch Sensor you can make your robot walk, talk, close a door, or turn off your TV.
There's also a Color Sensor that functions three ways: it distinguishes colors -- black and white, as well as a range of bright and pastel colors -- it distinguishes light settings, and it can be used as a color lamp.
And finally, the MINDSTORMS Software lets you program your robot. Use the software to create a program, and then download the program to the NXT by using the USB cable or the wireless Blue tooth connection. Mac- and PC-compatible drag-and-drop software gives you 16 building and programming challenges, from beginner to expert.
