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.

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 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.

In this activity, design and construct an RCX car that can bridge a one
foot gap without falling.

In this activity, design and construct an RCX fan with 2 touch sensors
and program it to run at variable speeds and have a stop/start function.
See the "Fan-Tastic" PDF for Detailed Instructions

In this activity, design and construct an NXT fan with 2 touch sensors
and program it to run at variable speeds and have a stop/start function.
