Today, I present the Formula Ev3: a racing car! Personally I like this model for its very clean profile, which aside from the cables, resembles pretty well a Formula 1 racing car from the eighties. It also features a openable front trunk, under which the steering mechanism are visible.
The building instructions of the Formula Ev3 are described in the “Lego Mindstorms Ev3 Discovery Book” by Laurens Valk. Check the video below for a demo for the Formula Ev3 performances 🙂 !

The Formula Ev3 features two Ev3 Large Motors to drive the rear wheels, and one Ev3 Medium motor to steer the front wheels. The steering accuracy is good as the motor shaft is smartly constrained to cut its natural backlash.
The vehicle is also equipped with the Ev3 IR Sensor, which can be used as a receiver for the IR Remote commands or to seek the IR Beacon when this mode is selected.
If you have had a look at the video or at the gallery below, you certainly couldn’t have missed the Ev3 Color Sensor brilliantly used as the back red light with which the real cars are equipped. That’s really cool!
- you can use the four main buttons to drive the vehicle, or
- you can activate the IR Beacon mode with the fifth top button so that the vehicle starts following you.
