GPS accuracy testing with LEGO bricks

fletcher gps4

Unlike normal GPS units, commonly found in smartphones or your car, that are accurate to roughly three meters, differential GPS uses two GPS receivers to get a reported accuracy of three centimeters! That’s a little over an inch! If this holds true, differential GPS could be used for a range of high precision applications. This […]

Iteration, collaboration, and documentation

Iteration 2 - Adds a touch sensor, ultrasonic sensor and a rudimentary envelope holder

Iteration, collaboration, and documentation are integral parts of engineering design. This challenge is intended to provide students with an opportunity to develop their understanding and appreciation of these important ideas. To run this activity, first divide the class into at least three different groups. Stage 1 Challenge each group to create a robot to meet […]

Iteration and efficiency


Efficiency is important in engineering, not only in materials but also time, money and energy. It is important for a young engineer to learn the value of an efficient product. Anyone can build a bridge with as many pieces they desire, but can you do it with fewer and fewer? Challenge: Build a bridge that […]

Learning sequence: Learn about gears


This suggested sequence of activities begins with an exploration of simple hand-powered gear trains. The second and third activities use gears to decrease the rotational speed of motor-powered music boxes and fans. The last three activities incorporate gears into cars so that they can win a “snail race” or climb steep ramps. This learning sequence […]
