Lesson Objective: To learn to program using light sensors.
Materials Needed: NXT kits, Tape that contrast the color of the floor, computers running MINDSTORMS NXTg Software.
Procedure:
1. Have the students build their cars. Be sure that the light sensor is pointed at the ground...

Objectives:
Kids will program motors to change direction 3 times using rotations, seconds, degrees, or unlimited DURATION and make a robot that does the Bunny Hop.

This steering wheel uses the HiTechnic accelerometer to determine the angle and send it to another NXT car over the bluetooth. The motor acts as a speed controller.

Using the Hi Technic Accel Sensor, these two programs send (via the Mail Icon) positional data from one NXT to another NXT, which receives that value and drives forward and backward. The speed of the motors is relative to the angle the first NXT is tilted.

The aim of this project is to show the nonlinear dynamics of a vertically driven pendulum using Lego NXT. I use this toy in my Nonlinear Dynamics classroom.

Below you find building instructions and a video of the toy.

A pendulum with a fixed suspension point has two eq...

For this activity you will need an NXT brick, a wire, an NXT proximity sensor, and computers running MINDSTORMS

1. Have student design an alarm box that will detect when a person approaches the box. If students want to use more than one proximity sensor or a different sensor as we...

In this activity, use an NXT car equipped with an ultrasonic sensor to navigate without bumping into obstacles such as walls or people.

In this activity, use an NXT brick equipped with two ultrasonic sensors to emulate a Theremin, an electronic instrument. One sensor will change pitch as distance to an object changes, and the other sensor will change volume as the distance to an object changes. The Theremin is meant to be played wit...

In this activity, use an NXT brick equipped with two light sensors to emulate a Theremin. One sensor will change pitch as the amount of light sensed changes, and the other sensor will change volume as the amount of light sensed changes. The Theremin is meant to be controlled with the hands, but any ...

Using one ultrasonic sensor, two touch sensors, and the NXT buttons, build and program a guitar with an NXT brick as its base element. Use the touch sensors to raise and lower the sound one octave each, use the buttons on the NXT to control the emission of sounds, and let the ultrasonic sensor contr...
