NXT sensors – LEGO Engineering. Touch Sensor. The Touch Sensor gives your robot a sense of touch. The Touch Sensor detects when it is being pressed by something and when it is released again. Suggestions: You can use the Touch Sensor to make your robot pick up things: a robotic arm equipped with a Touch Sensor lets the robot know whether or not there is something in its arm to grab. Or you can use a Touch Sensor to make your robot act on a command. For example, by pressing the Touch Sensor you can make your robot walk, talk, close a door, or turn on your TV. How to Program the light sensor on a Lego Mindstorms robot The light sensor on a Lego Mindstorms NXT robot can be used to help the robot navigate obstacles or follow light sources. Learn how to program light sensors and the calibration program in the Lego. Sound Sensor. The Sound Sensor can detect both decibels . A decibel is a measurement of sound pressure. BA: in detecting adjusted decibels, the sensitivity of the sensor is adapted to the sensitivity of the human ear. In other words, these are the sounds that your ears are able to hear. B: in detecting standard . Thus, these sounds may include some that are too high or too low for the human ear to hear. The Sound Sensor can measure sound pressure levels up to 9.
ECE 1882 Lab 3: Light Sensor February 27 & March 1, 2007 With all this said, let’s build a line follower program! Create a new NXT program. Save the program as “NXT Lab 6b.rbt” 3. A logic variable will be used to toggle between turning left and right. B . Sound pressure levels are extremely complicated, so the Sound Sensor readings on the MINDSTORMS NXT are displayed in percent . The lower the percent the quieter the sound. For example: 4- 5% is like a silent living room. Light Sensor. The Light Sensor is one of the two sensors that give your robot vision . The Light Sensor enables your robot to distinguish between light and dark. It can read the light intensity in a room and measure the light intensity of colored surfaces. Suggestions: You can use the Light Sensor to make a burglar alarm robot: when an intruder turns on the light in your room the robot can react to defend your property. You can also use the Light Sensor to make a line- following robot or a robot that can sort things by color. Ultrasonic Sensor. The Ultrasonic Sensor is one of the two sensors that give your robot vision . 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 measures distance in centimeters and in inches. It is able to measure distances from 0 to 2. 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 . Objects made of soft fabric or that are curved . This lets your control your robot. The Rotation Sensor measures motor rotations in degrees or full rotations . One rotation is equal to 3.

The Tufts Center for Engineering Education and Outreach (CEEO) in Boston, Massachusetts, is dedicated to improving engineering education in the classroom, from Kindergarten to college. The Center houses faculty, staff, and graduate students from engineering disciplines and the education department.
