Making Lego cars roll downward on a Lego treadmill with an incline, using various methods to create tire friction, in order to make the cars roll downhill indefinitely. The angle of the slope is gradually increased to intensify this challenge. The final challenge is the automation of the treadmill to have an official Lego Technic car, without any modifications, roll on it indefinitely. Two Lego color distance sensors and the Powered Up app are used to create a program that constantly adjusts the tread speed and incline angle. The treadmill internals consist of 2 powered up hubs and 4 Buwizz motors. The treads are 3D printed custom made parts.
