Objectives:
Kids will program motors to change direction 3 times using rotations, seconds, degrees, or unlimited DURATION and make a robot that does the Bunny Hop.

This steering wheel uses the HiTechnic accelerometer to determine the angle and send it to another NXT car over the bluetooth. The motor acts as a speed controller.

This lesson plan and student "journal" page ask students to design and build moveable models of animal structures. A rubric is included for students to use to critique their models.

Using beams, connector pegs, and craft materials (such as foam and glue), students create a handle for a stamper. Students will need to build the handle and attach the foam shape. Students test it out by using ink and putting a stamp on paper.

Using the Hi Technic Accel Sensor, these two programs send (via the Mail Icon) positional data from one NXT to another NXT, which receives that value and drives forward and backward. The speed of the motors is relative to the angle the first NXT is tilted.

Popeye the Crab (named for his eye that continually popped off during construction) is a LEGO creation fabricated by a 14 year old boy. Popeye walks with a 3-point motion and runs automatically with a switching system on the back, which controls the pneumatic legs.

How can the robot know the exact tile it is on, when moving around in a room with floor tiles sized 1x1 foot each?

(What if we want to know the exact position to the closest centimeter?
What if we also need to know the exact direction it is facing?
Beginning to sound lik...

In my physics class, the students modified their "Going the Distance" robots to push on a ball. This was an opening activity for my "Force and Motion" unit. We used some fabric taped to the floor as a hole.

In my physics class, my students create physical pendulums to study oscillations. They use the NXT and a light sensor to test their predictions regarding the period of the pendulum's oscillation

Today you won't have troubles to buy an electronic compass from the shelf. But, sometimes you want to understand - or as a teacher - to explain how the compass direction can be turned into digital information. This sensor got its name, because it is made of a few LEGO pieces, the RCX, a magnet, a li...
