"Having Fun Gearing Up With LEGO EV3 GEARS!!!"

[@nathanward8055]

What a great idea to teach the kids to gear up and gear down. Thanks for sharing your ideas!

[@Qloqgente]

i did a fan with this comtraption

[@LEGORoboticsMrHino]

Those gears can get things spinnng crazy fast!!

[@muhammadsharifzoda148]

Wow thats good Ilike it Mr.Hino

[@leukanttila8233]

Nice video! I made a robot with these. Also when is the next leaderboard update and mission 5 coming out in GAME ON. I'm on max points. (:

Tomorrow Leuk!!!

Theoretically could you just endlessly do this until you reached light speed and beyond?

[@hydroworld-soontobemigrate6160]

Absolutely not (Well, at least not with LEGO gears). Remember, speed and torque (turning force) are inversely proportional. That means that the more you increase speed, the more you decrease the output turning force. This also means that the more you gear up, the less weight you are able to rotate. That's why many gearboxes focus on increasing the output turning force at the cost of speed, so that they have enough power to rotate heavier objects. This is especially important for wheeled vehicles, whose rotating parts (the wheels) are consistently in contact with ground. This contact creates more friction that the motor must overcome in order to move the vehicle. The EV3 Medium Motor only has so much torque, you can only gear up so many times before the friction becomes too great for the motor to overcome. That's when it begins to stall, or even break if it tries too hard. So unless you want to risk your motors, I would highly recommend never attempting to do that.

@@colonelpotato An enormous amount of power that no existing LEGO motors can provide.

[@stonksmaster6982]

You need infinite energy to make something with mass move at the speed of light, let alone how much force you would need to turn the first gear or how much force a Lego gear can handle

[@MegaMike1]

Could I do that on 45444 kit?

[@LEGORoboticsMrHino]

Which kit is that?

[@LEGORoboticsMrHino]

Oh that's the Home Edition. Yeah you should be able to!!

@@MegaMike1 Whoops my bad....the Education Version (45544) and the Home Edition (31313). I do all of my Robotics with the Education version. I also mix in the Expansion Kit.

I think the large gear is 40, so the ratio is actually 5,

[@wg69]

Your wrong

[@michaelyang1459]

I think the large gear is 40, so the ratio is actually 5, enjoy your vids though.

[@LEGORoboticsMrHino]

You're right Michael.... 40 teeth. Thanks!!!

[@miguelnassour110]

@@LEGORoboticsMrHino It’s a 1:25 ratio

[@marcuslindain6361]

make it more faster by adding more 8 tooth and 64 tooth gearss

[@stadiasweat8184]

unfortunately this makes the torque really high

[@Superfredd]

Large is 40 teeth not 64

[@LEGORoboticsMrHino]

Yep...my bad you are correct.
