Everybody gangster till thy Lego tank start neutral steering.

[@carbonwolf1087]

Yeah

[@Sam-zo8lz]

True

[@Lightdayleland]

yup i hear u

[@ju.h_man]

thats what i searched for...

[@tuankiettran8811]

Dual Differential Tank Drive.

[@brianjennings3172]

Good design. You need a few different angles to see it all better.

[@WhiteHatMatt]

I love this but I do have a suggestion: a gear reduction between the steering motor and the steering box would give finer gained control over the steering.

[@severinghams]

i think it would be better if the drive connected straight to the diff ring gear instead of the center inputs and the steering was the center

[@ThePulmentinum]

AFAIK that's how real tanks steer, except that they have epicyclic gearings instead of the two differentials.

[@Shorjok]

@@ajz562 technically yes, if you use the turntable pieces it should be possible

[@Uardef]

I had the idea also but only in the mind. good job

That is too Genius!

got this randomly recommended just now... but where's the follow up vid?

[@rewrew897]

Would be great if someone could remake this as a file for the LEGO digital designer program You can then use that to purchase a set with all these parts, I think

Andrew Glawson' Checkout Bricklink’s “Studio” program, you’ll thank me for it! 🙂

[@acasualweeb.2394]

I like how there are two differentials on the top

This Maschine... A.k.a. subtractor

[@myplasticbricks2239]

Very cool implementation of a subtractor.

[@jeffmclearen229]

Badass build

[@PLASMA_2005]

Perfect for the Lego train remote tbh

[@d4ro]

while the mechanical solution is very elegant, i think more effective will be one motor per side (and use electronic mixing) because for forward driving it would have full power. by your solution the tank will have a boost when driving a curve which make it more agile

[@psh1491]

good

[@y_us_12]

I thought about this design over two motors for each track. The only advantage is perfect synchronization between two sides. Should go perfectly straight. But it is not efficient. You have two motors, but when you want to go fast, only one motor is used. You may have bigger motor for straight movement, but in this case your steering is weaker. So I came back to two motors for each track.

[@matsv201]

This design is much more realistic to a true tank

[@JoeyLovesTrains]

I love it when people over complicate the simplest you ever! It’s so cool!! Not trying to sound sarcastic, it’s super cool.

[@matsv201]

It's really not that complicated. If you want neutral steering this is probably as simple as it gets

[@Uardef]

I wanted to take 2 motors dierekt to differential fo steer.

[@matthewallred7471]

Thank you! Thank you! i have been designing a transmission system for a vehicle and i couldn't figure out the use of two gear boxes. After seeing this video this helps me a lot more.

[@steelyray]

I think that you should try and reverse the dif inputs so that the main dif gear drives the tank and the internal gears run the steering.

Awesome👍👌☺☺😊😊

What in the ding dong diddly fuck did I just watch 😍

[@ezequielsanuy8895]

What if you put one electric motor for each track independently

[@hansherrman5147]

Impressive

[@user-qz6my3kk9j]

謝謝妳我終於有個思考的念頭，我家有LEGO所以我還是用看看感謝

[@user-mr5hk7rc4l]

Я как инженер скажу, используется 2 мотора, и огромный механизм, чтобы управлять гусеницами, но смысла в этом нет и не будет, если можно просто поставить моторы на прямую к гусеницам. Но конструкция мне довольно сильно понравилась.

[@minortoterona2947]

Ну как минимум данная конструкция извратно-упрощенно показывает как работают одномоторные гусеничные транспортные средства, и как минимум неплохое такое упражнения в механике (если самому делать думать). Но вы абсолютно правы, хотя то что любят делать другие люди (коробки передач). это очень и очень компактное и элегантное решение %)

[@techmatt3088]

I will try to explain the advantage of this kind of steering gear later because there are some comments like yours. But thank you for liking the design.

[@techmatt3088]

Thank you for praising the design

[@ara_ara-]

Oh man oh god oh man!

[@kennethtaber9621]

Nice work, can it be bought as a kit??

[@Sparkfilm-yy8ye]

this is cool but extremely inefficient, i tried this model myself and the gears grinded alot and it struggled to move. also, why not put a motor for each track instead

[@misterzed3387]

satisfaction

[@bagger2222]

classic case of over-engineering. there are better ways to do this. you can easily do it with one differential gear. connect one motor to one track, connect the second track via the differential to the first track, connect the second motor to the differential housing. viola, same feature, yet only 6 gear wheels instead of 19. basically just remove one of these differentials and connect the free pin straight to the track. the second differential is redundant. or... just connect one motor to each track. ;D

[@techmatt3088]

sorry for the late answer. This wont work because the tracks would run in opposite directions. And the second motor would only increase or decrease the speed of the second track.

[@bagger2222]

​@@techmatt3088 i now see the beauty in your version. one motor for moving forward, another motor for neutral steering. my version would need less gears, but another way of motor control. however, since youre using 2 motors, i guess id just connect one motor to each track --> zero gears. ^.^ challenge: try build one with only one motor and one differential! :)

[@charleswatts1864]

If it uses two different motors, why not just make a right side / left side drive system where each side is powered by a separate motor?

[@tasteless_5915]

Instructions.?

[@Timo.krebss]

Whats better in this complicated thing than if you just place one motor for one axle?

[@techmatt3088]

this will work of course. But the real Tanks use steering gears like this and I wanted to build such a thing. One problem with two motors is to sync the two tracks at higher speed. One motor for the speed and the tank will go exactly forward . The steering motor smoothly overrides the speed of the tracks so you can do very soft curves.

[@Timo.krebss]

@@techmatt3088 aaaa thanks In lego it isnt as complicated as in real world thanks for the amswer

[@user-mi6hn3bk3z]

Супер! Жаль нет детальной сборки. Совершенно не понятно сколько моторов и какой пульт. Остаётся только гадать.

Could you please explain your idea ?

TechMatt with the wireless controller, you can add two on either side and they will spin like this

[@vintyprod]

The transmission in the video is the smarter solution

[@willhindley1]

Hi

[@thomasrobinette3227]

Way over-engineered. If u have 2 motors just let each one drive a track.
