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.

Students will program an ROV (RCX vehicle) that will travel from Earth to an assigned planet.

Lesson Objectives:
* Program a RCX ROV to travel from Earth to an assigned planet.
* Use this activity to learn about the solar system.


Materials ...

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.

In this activity students will construct a tower that is at least 4-6 inches high. The tower must withstand first the weight of a stack of books, then themselves and then you.
Concepts: 1) building
2) sturdiness

Learning Objective:
Build a robotic NXT LEGO car equipped with a light sensor and program it to drive at a speed based on the light sensor input.

Student Challenge:
Build and program a two-motor car equipped with a light sensor. The car should drive forward and will ha...

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.
