Can a Lego Car Roll Downhill Forever?

Рет қаралды 8,710,904

Күн бұрын

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.

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.

An easy way to get it to roll 'forever' (if friction-induced wear and failure of the treadmill and car weren't factors) would have been to use a curved treadmill. Imagine a U-shaped treadmill, so there would always be a point lower than the two ends of the treadmill. If it were sufficiently long with each end high enough, the car would be unable to roll off the end.

@ZachAttack6089 3 ай бұрын

I was thinking the same thing. You could probably do this pretty easily by putting some slack in the treadmill. So if it starts rolling forward then its back wheels will sink down, causing it to level out and lose speed and get pulled back up. And if it starts rolling backward then the front wheels will sink in, angling it down so that it gains speed and rolls back down.

It would not go forever because the batteries for the fans would die. I really liked the passive elements you were using before that point though. Generating downforce with a fan powered by the rotation of the wheels was a really good idea, and the fan idea in general kinda reminded me of the fans on the bottom of micromice (tiny racing maze solving robots) that they use to hold a vacuum between them and the surface they are on. Actually, those are so light and have so much downforce that they could probably drive upside-down lol.
