In this activity, a group of people use a number of RCX's to determine one another's birthdays.
See "Birthday Decoder" PDF for detailed instructions.

In this activity, design and construct an RCX sturdy car and program it to be controlled by touch sensors that can push “dirt”
See "Bulldozer-RCX" PDF for detailed instructions.

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 ...

This is a tip on how to remote control a car in ROBOLAB, using the buttons on the NXT.

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...

In this activity, design and construct a windsail mechanism connected to a rotation sensor and an RCX to measure the speed of the wind.
See "Capture the Wind -RCX" PDF for detailed instructions.

In this activity, design and construct a windsail mechanism connected to
a rotation sensor and an NXT to measure the speed of the wind.

In this activity, design and construct an RCX or NXT crane controlled by motors and a touch sensor remote control.
See "Crane" PDF for detailed instructions.
