Can a Lego Car Roll Downhill Forever?
Ғылым және технология
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.

50 degrees with the flat fan reminds me of going upside down in Mario Cart when the wheels turn sideways
Excellent empirical demonstration! It would be neat if you also did a balanced free-body diagram for each configuration, to show the balanced drag force vs other forces involved.

It’s lego
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.

Anyone else hoping to see the downforce propellers reverse and turn the thing into a drone? Also, the durability of that treadmill!
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
