In this activity, use an NXT car equipped with a light sensor to determine the hidden Morse Code message (under a table or in another room). The message will be determined using light sensor collected data on a pass over of the message.
See "Morse Code" PDF for detailed Instructions

In this activity, use an NXT car equipped with a light sensor to determine the hidden letter message (under a table or in another room). The letter will be determined using light sensor collected data on 3 passes over of the letter
See "Find The Hidden Letter" 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.

Determine the best structure for a sturdy car. Motors do not have to be attached, but the car must roll with wheels and skid plates. To test the car design drop the car from a height of 4in to check if it survives.

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 ...

In this project I wanted to construct a remote controlled robot which moves much like a real snake. The snake robot consists of four links and three joints, being the motor axels. Each link is equiped with a set of free rolling wheels. The serpentine motion of a real snake is only possible due to an...

In this activity, design and construct a chair that keeps Mr. Bear (a floppy stuffed animal) from falling backwards, forwards, to the left and to the right. The safety of Mr. Bear is in your hands.
See the "Chair for Mr. Bear" PDF for detailed instructions

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.
