Create and build the smartest, strongest and most advanced Lego robot ever with the Lego Mindstorms NXT! This amazing robotics toolset provides endless opportunities for users to build and program robots that do what they want via the intuitive programmable software. Including an all-new Intelligent Brick with a 32-bit microprocessor, 3 Interactive Servo motors, a sound sensor, an ultrasonic visual sensor, an improved touch sensor, and an improved light sensor – meaning that this robot can walk, talk, hear, touch and see! But not only that, you can now even command your robot with your mobile phone via Bluetooth. The NXT is the most amazing Lego robot ever! Featuring 519 specially selected LEGO TECHNIC elements for sturdy and durable building and improved functionality and movement, 4 input ports, 3 output ports and 7 6-wire cords Matrix display, Piezo speakers, USB 2.0 and Bluetooth support and an easy-to-use PC and Mac compatible programming software. The Touch Sensor: Use a Touch Sensor to make your robot act on a command. By pressing the Touch Sensor you can make your robot walk, talk, close a door, or turn on your TV.The Sound Sensor: The Sound Sensor can detect both decibels [dB] and adjusted decibel [dBA] and can measure sound pressure levels up to 90 dB - about the level of a lawnmower. You can program your robot to start, stop, or make a noise on command when hearing sounds!The Light Sensor: One of the two sensors that gives your robot vision, enabling it to distinguish between light and dark and also measure the light intensity of coloured surfaces. Use the Light Sensor to make your robot a burglar alarm - when an intruder turns on the light in your room the robot can react to defend your property!The Ultrasonic Sensor: Enables your robot to see and detect objects. You can also use it to make your robot avoid obstacles, sense and measure distance, and detect movement. The Ultrasonic Sensor uses the same scientific principle as bats: it measures distance by calculating the time it takes for a sound wave to hit an object and return – just like an echo.The Servo Motors: These 3 motors give your robot the ability to move. If you use the ’Move’ block in the Mindstorms NXT software to program your motors, the two motors will automatically synchronize, so that your robot will move in a straight line The Software: Enables you to program your amazing robotic invention and upload your programs to the NXT via USB or Bluetooth connectivity. This intuitive MAC and PC compatible drag and drop software powered by LabView comes with building instructions and programming guides to enable you to easily get started with constructing and programming with Mindstorm NXT. It’s easy to get started as the Lego Mindstorms NXT Software comes with building and programming instructions for 4 cool models that you can build and program to do what you want.
