Can a Lego Car Roll Downhill Forever?

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.

@Appletank8 10 месяцев назад

Not quite accurate, but you have the idea! Their cornering speeds are quick because they produce downforce, which doesn't acually lower center of gravity.

@OddJobEntertainment 10 месяцев назад

Wow, this is such a great demonstration of a lot of physical properties. Gravity is acting on the car which will cause it to accelerate until the forces holding it back reach an equilibrium. So if the frictional force, or drag, etc equal the gravitational force, then the car stays in place. The changing angles is also great because it shows how the y component of some of the forces can be altered. This would honestly make a great demonstration in physics classes.

For each angle you add, you must be sure the wheels spin fast enough to counter the force in the XY axis on the angle. Basically, the more steep it gets, the faster to balance with gravity
