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 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.

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, construct and program an RCX or NXT dancing
robot that has at least two moving parts and at most two motors. Set your
robot's dance to music.

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.
