Wouldn’t work for every car, because the mechanism is car dependent, not ramp dependent. It would need to be adjusted for every car that you choose to display.
@@foopymaster1757You could fix that, by sensoring the cars position and switching the ramps motor accordingly. With the robotics stuff it should actually still be possible to make such thing entirely out of Lego.
funnily enough some cars actually do have such fans under the car, the only difference being that it sucks air from below the car instead of pushing the air above it(and it's also usually hidden from view lol)
a good proportion of performance race cars can produce downforce exceeding their weight at speed, without fans. This video is a good indicator of how downforce works. it's just replacing shaped bodywork with fans since this work isn't a wind tunnel.

The type of system is called a PID control loop. It's quite neat, is one of the fundamental components that makes things like drones keep themselves level.
Nahh, car industry doing that all the time,i mean not with propeller on the car xD but shifting weight, reducing drag. Engine placement and type of drive make world of difference in driving performance.
So cool project. I was thinking that 90° could be impossible, but you manage to solve it! You deserve 100 millions subscribers, thanks for your videos!
I knew it would end with closed loop control... I'm impressed you managed to get basically everything up to 90° working in a steady state with just weight/drag/downforce tweaks though
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.
This is amazing! I bet this will encourage lego fans to study engineering, engineers to get into lego and young people to get into both. I was shocked by the builds and results. Keep doing what you do. Innovation leads to progress and vice versa!
Appreciate the level of engineering, all the approaches with air braking and propellers. How many days making of this video actually took? Did you make it in one go, or took breaks for thinking and prototyping?
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.
Awesome vid, really surprised (and appreciate) the angle you managed ha! Do you think you could try experimenting with balancing machines? It would be crazy interesting if you manage to build one without any electrical speed control or mindstorm sensors.
holy shit this was one of the most insane videos i’ve watched! casually just shows how engine breaking and regenerative breaking works. as well as increasing down torque using reverse propellers, loved this!!

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
I never knew how advanced thing had gotten in the world of Lego technic. As soon as he pulled out the programming software my mind was blown. Like I seen earlier Bluetooth controlled vehicles before but it never occurred to me that this level had been out there I was just unknowing.
3:42 "at 45° more weight won't increase tire friction" Well, it would XD I see your point but it's a bit inaccurate in this phrasing and it hurts my soul in this otherwise fabulous video So at 45° the tangentional and normal components of the weight force will be equal. An since the friction coefficient is always
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.
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.
I feel like the fake piston engine would have been significantly more effective by covering the pistons. The compression would have resulted in basically having a jake brake. Awesome video!
Bad Piggies is exactly like humans in the early 1900's, bulding stupid contraptions, tho the pigs' contraptions actually worked. Maybe those pigs have more iq than an average human in the early 1900's.

There's been a few school physics experiments I've had like this. You make it look easy lmao Also idk why but I love the little angle indicator at the bottom of the treadmill
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.
