The original Mindstorms Robotics Invention System kit contained two motors, two touch sensors, and one light sensor. The NXT version has three servo motors and one sensor each for touch, light, sound, and distance. Lego Mindstorms may be used to build a model of an embedded system with computer-controlled electromechanical parts. Many kinds of real-life embedded systems, from elevator controllers to industrial robots, may be modelled using Mindstorms.
Mindstorms kits are also sold and used as an educational tool, originally through a partnership between Lego and the MIT Media Laboratory.
Alpha Rex Robot Type: Humanoid - What this robot can do: Alpha Rex performs tasks that only the most sophisticated robots can do... Walk on two legs like a real person! With built in rotation sensors on the two Servo Motors powering his legs, and an Ultrasonic Sensor nabling Alpha Rex to see, you can program Alpha Rex to go where you want with precision! He Sees! (With an Ultrasonic Sensor), He Hears! (With a Sound Sensor), He Talks! (With a built-in Speaker on the NXT brick and sounds from the NXT Software), He Walks! (With two Servo Motors), He Feels! (With Touch and Light Sensors)
The NXT is the brain of a MINDSTORMS® robot. It’s an intelligent, computer-controlled LEGO® brick that lets a MINDSTORMS robot come alive and perform different operations. Motor ports: The NXT has three output ports for attaching motors - Ports A, B and C Sensor ports: The NXT has four input ports for attaching sensors - Ports 1, 2, 3 and 4. USB port: Connect a USB cable to the USB port and download programs from your computer to the NXT (or upload data from the robot to your computer). You can also use the wireless Bluetooth connection for uploading and downloading. Loudspeaker: Make a program with real sounds and listen to them when you run the program
