Impossible Climb - Flywheel Lego Vehicles - Making and Testing

[@DrEngine]

Which flywheel-powered models did you like the most? Do you think they perform better than those with electric motors?

[@a.benaway_racing]

When you showed the nano crawler you had the vertical input shaft driving each wheel and they were going opposite direction as it should. When it started climbing they were obviously all spinning in the correct direction. What changed?

[@Vijayan-m7n]

​@@1islam1that's not the topic of this video excuse me

[@Sparkfilm-yy8ye]

I would like to see a motorized vehicle that also has a flywheel, I am curious to see if that would improve the efficiency of the vehicle

the amount of slack on those treads and chain drives dealt psychic damage to me

It's pissing me off with a burning passion

[@cynohammond-mw3ow]

He literally had to add another chain because the tracks were slipping the tracks wouldn't slip if they're tight

[@UmbralKnight1344]

@@cynohammond-mw3ow when i saw that i was like "yeah that's gonna happen when you have that much slack"

[@parandomal]

Tracks need to have a decent amount of slack to actually work. The real issue was the drive wheel being in a spot where that slack goes when the track is up to speed.

[@loganjamesonhatch5050]

That chain slack is gonna kill me, not just semi-loose but fully unnecessary links

[@80evgeniy]

The drive chains of friction cranes/shovel is similar slacked, but working.

I think the flywheels could have been spun more - perhaps the results would have been better.

[@LiamLovesCars]

I wanted to say the exact same thing, thank you

[@SWellWellWell]

Flywheels are incredibly efficient at storing rotational energy. They convert kinetic energy into rotational motion and can release it quickly when needed. This makes them useful in applications requiring bursts of energy.

[@Superwazop]

[@Whatshuangdoin]

The tracktor could be improved by spinning the flywheel the opposite way to take advantage of the gyroscope effect

[@DrEngine]

Nice suggestion! Thank you!

[@Chauzuvoy]

Is there a reason you don't use a chain tensioner for any of these? Is it just complexity of the build or is there some kind of performance implication that I'm not aware of?

[@WynterLegend]

If you put a tensioner in your track, it wouldn't slip. Same goes for chain belts. Same principle.

[@BrickASMR777]

4:33 The redundancy of the tracking chain was likely the reason for the unsuccessful challenge? I'm really impressed with your overall challenge series.

[@althejazzman]

At the end, The Shredder reminded me of a battery operated toy car I had as a kid called Animal. It had claws inside it's tyres that would extend when the car struggled for grip. Really cool design, and I loved seeing what it could do.

[@Whatshuangdoin]

Why dont you use track tensioner?

[@DrEngine]

Lasciate ogne speranza, voi ch’entrate 😉

[@ristopoho824]

Hm. Interesting. The flywheel having a set amount of energy to go by forces you to think about the efficiency too, not just about the amount of climbing power. Having the vehicles use the same flywheel accelerated by a motor to a set amount of speed would easily give them just the same amount of energy. Making the whole run about not wasting energy on the internal and external losses. Another way to give them the same set amount of energy, rubberbands. That would be a video i'd like to see too.

[@tetyanazayatsteza2406]

[@Landos_authentic]

Am I the only one confused about how the first car with motors works? The tires should be spinning in opposite direction right?

[@aidencarlton8309]

The grey gear does not have the teeth that grip the axle and ao spins freely. The tan gear is driven and connected to a solid axle. The grey gear doesn’t seem to do anything practical

[@MrAtda]

I feel like of the gyro were spinning the other direction the force wouldn't have doing the initial treaded one backwards. Maybe could've gotten up that last test. Love the vids though!

[@DrEngine]

Thank you 😊 I'm glad you like it

[@ELBASIC]

0:40 Bro got the lego dyno

[@liamchristians7555]

All those motor powered builds had power but didn't have any torque, because torque would've gotten the 20° slope, not power since it just dug into the cork pieces

[@mcgo3595]

Yeah.. Some gearing changes would have made all the difference. 👍 Enjoyed nonetheless.

[@SmartBrickChannel]

Really nice video. Good work. 😊

[@DrEngine]

Many many thanks

[@EffYoInfo]

The one with the bigger wheels in the back, seems to have a slight rear biased overdrive (because of a larger final drive / wheel). Model RC rockcrawlers will add a larger final drive to the front wheels, as it actually helped claw up and over steep obstacles. I bet adding the larger wheels to the front would’ve performed better than adding them to the rear. My two cents 😂 Fun video, keep them coming!

Why are you Always leaving so much slack in your Tracks and belts ? Tighten them correctly and they Work Wonders. The thightening mechanisms are Not for nothing in all tracked vehicles on the world.

[@DrEngine]

Thank you, great suggestion ☺️

[@parandomal]

It's important to note that some slack is necessary for tracks to work as intended. Probably not this much, but better drive wheel placement seemed enough this time.

[@Beam25hero]

what is a flywheel?

[@JackCreator73]

A flywheel is like a spinning top. When you spin it really fast, it stores energy, like when you wind up a toy car. Then, when you let go, it uses that energy to keep spinning or to make something else move. It’s a clever way to save energy and use it later!

[@Beam25hero]

[@MAMAboyAHH600]

not only toy cars but also in real cars,the only difference is that its made from metal and much more heavier,but when you question "why do need it to be heavy" you might ask its just simple,it is used for the engine,also btw without a flywheel the engine will die when your trying to change gears in a manual vehicle "cluch included"

[@gumgumdumdum5824]

Add a spring loaded tensioner gear to your tracks and chains to remove the slack.

[@hansonsen]

You should try supporting tha catterpillars in the middle so that the weight is distributed equally.

[@PhilNubbins]

I’m willing to bet that if you let some of the flywheels rev up for longer you would get better results

[@joshuasams312]

For tracked vehicles you may want to add a spring powered tension wheel to keep the tracks at proper tension reducing the cancer of them slipping.

[@parandomal]

Slack is fine, especially since these vehicles aren't meant to turn, as long as the drive wheel is located so that it's always engaged, usually front or back.

[@JonWilsonPhysics]

Maybe a screw tank could climb through this material

[@tkhamau]
