A lego technic 2 speed automatic gearbox is put to the test by incorporating it into a lego 2 speed automatic car.  This lego 2 speed automatic gearbox implements a number of design principles aimed at improving the gearbox performance - namely of placing the torque detector on a separate pa...read more

A four legged robot dog made out of Lego Technic is demonstrated. The robot is made of 4 powered up medium motors for the legs and one for the balancing mechanism on top. The robot dog can walk forward, backwards and can turn left and right. It is controlled via a Powered Up app program running o...read more

Here is a challenge to build a fully functional Remote Controlled Lego Technic car using only 100 parts. This video shows the result.

This is an improved version of the Lego Technic Omni Directional RC Vehicle v1.0 (https://youtu.be/crj3kOiSmHg). Several improvements are made in this model mainly around the mode switching from driving forwards and backwards to rotating on the spot. In the previous model there was a lot of gear ...read more

This Lego Technic RC vehicle is modeled on the Roomba vacuum cleaner from iRobot. The Roomba can drive forwards, backwards and rotate on the spot. This RC lego technic model attempts to do the same but with four wheels instead of two, similar to a supermarket trolley. The vehicle can switch betwe...read more

Here I present a lego technic tank driven by a single lego power functions motor. The lego RC tank can be controlled remotely using a single remote channel and driven forwards, backwards, and steered left and right. These functions are implemented by using a single large PF motor and exploiting t...read more

An improved version of a lego technic RC 3 speed gearbox is implemented into a remote control lego car. This video shows three main improvements over the previous gearbox design. The first is an improvement is to replace the 90 degree bugatti stepper  with a PF servo motor reducing the gearb...read more

This video explores the use of the lego technic "smoothly switching 2 speed automatic gearbox" inside of a test car to see how well it works to climb up a ramp.

The gearing ratio of the 2nd gear of the 2 speed automatic gearbox can be set using a manual 4 speed gearbox to choose...read more

A 1,023 speed gearbox has been built into a Lego Technic remote controlled car chassis. The car can be steered and driven via remote control using two channels. The gears can be manually changed using ten selectors that drive ten differentials. This allows for one of 1023 different speeds to be s...read more

Here I present a Lego Technic Spirograph machine programmed using Powered Up. The powered up controller is used to maintain the desired gearing ratio between the turn table and the inner gear to draw a spirograph that replicates the real original spirograph drawing toy.
