1. LEGO Mindstorms NXT Introduction

2. Component NXT Brick Touch Sensor Light Sensor Ultrasonic Sensor Interactive Servo Motors MMN Lab.

3. NXT Brick An intelligent, computer-controlled LEGO® brick. The brain of the NXT robot. Can take input from up to four sensors and control up to three motors. MMN Lab.

4. Touch Sensor Enable the robot to respond to obstacles in the environment. Pressed: one Released: zero MMN Lab.

5. Sound Sensor Enable the robot to respond to sound levels. The Sound Sensor detects both dB and dBA. Can measure sound pressure levels up to 90 dB. MMN Lab.

6. Light Sensor Enables the robot to respond to variations in light level and color. Higher numbers indicate more light. MMN Lab.

7. Ultrasonic Sensor Enables the robot to measure distance to an object and to respond to movement. Able to measure distances from 0 to 2.5 meters with a precision of +/-3 cm. Large-sized objects with hard surfaces provide the best readings. MMN Lab.

8. Interactive Servo Motor Ensure that robots move smoothly and precisely. Have a built-in Rotation Sensor. (accuracy of +/- one degree) MMN Lab.

9. Requirement Hardware –At least one NB per group. Software –JDK 1.6 –lejOS –USB driver MMN Lab.
