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...

Using a sound sensor and an NXT car, design a robot that moves forward when a person claps somewhat softly, and stops when a person claps loudly.

Collect and display sound data from the NXT sound sensor in real time on the LCD display of the NXT. Also include the ability to pause the data collection by bumping a button to view a particular screen of data until another button is bumped.

In this activity, a group of students each build an RCX robot. Each RCX is assigned a number. It will then have to tag the other RCXs with the number by using mail. 5 tags and the RCX takes on that RCX’s number. The winner is the RCX that has given its number to the most other RCXs at the end...

In this activity, set up an NXT “voting booth” to gather data using touch sensors. The presses will be recorded and plotted into a graph.

In this activity, design and construct an RCX tractor that is capable of pulling a heavy load across a floor. (NOTE: Gears will be needed.)
