Lego Technic Single Motor Tank V2.0
Вставка
- Опубліковано 15 жов 2024
- Here I present my second new and improved version of a lego technic tank that is driven by a single lego power functions motor. In this version the gearing mechanism has been optimized and far fewer gears are used to create the four different track direction combinations, namely both forward, both reverse, one forward & one reverse (turn left), and the opposite to turn right. Also the motor has been upgraded to an XL power functions motor instead of the large power functions motor. This gives an extra 0.5 watts of peak power.
The lego RC tank can be controlled remotely using a single remote channel and driven forwards, backwards, and steered left and right. These functions are implemented by exploiting the direction of rotation of the motor to either drive the tank or select one the four track functions.
This is done by a swinging liftarm with a gear that connects the motor output to one of two separate axles - one for driving the lego tank and one for selecting the track functions.
The track functions are built using 2 orange rotary catches to switch a lego gearbox design that allows both tracks to be selected to drive forwards or backwards or to drive in either of the two opposite directions for steering.
The track function selector uses a 90 degree stepper and a knobbed wheel to drive the rotary catches.
The lego technic tank has an indicator on top to show which function has been selected.

Cant wait for the youtube algorithm to pick your channel up and recommened it
LOL same! haha. 😂
I really dont understand why your channel hasnt got more subscribers. I mean the quality of your videos is outstanding, especially the 3d animation in the beginning and the things you build are extremely clever! Never stop making videos, your going to get noticed more eventually :)
Greetings from Germany
Hi Blocksers. Lol thanks - I guess not enough people are interested in my videos. I am not too unhappy with the number of views and subs etc. I do it for fun!
Damn that's a good animation
Holy shit, I discovered that direction-based gear switching concept earlier but didn’t know a practical use for a transmission- here it is popping up half a decade later!
Hi Mate, yeah it's actually a great and under utilized method! 🙃
A genius feat of engineering. Well done!
I'm a total newbie to modern lego technic , its come on leeps and bounds since the early sets and gears. During lockdown I past some time away with the Lego Land Rover Defender kit the gear box realy impressed me . To see what you have done with it , it's amasing , thanks for the video. I would love to replicate your desighn . Have you any build instructions please.
Hi Gordon, thanks for your comments. Very pleased to hear you have discovered Lego technic - there are many amazing and exciting sets out there. I hope to create the build instructions for this model sometime - you will need quite a collection of parts to be able to make it or you have to order them specifically.
Awesome design! Hmm guess I should go change my video title now
great stuff mate
Cheera Alex. Happy to hear you enjoyed it.
it would be nice to see a tank that has gears for each track so different radii can be driven. this could be done with 2 motors each driving a one motor gearbox
Hi Hans, Yes that's a great idea - that should be possible.
@@TechnicBrickPower this would be like in a real tank
that track looks like an old british design, cool!
Hi Aleksander. Awesome didn't know that - I am not much of a tank expert. 😂
the british invented tanks and the track shape was very similar, cool design tho!
@@TechnicBrickPower you can search in youtube oversimplified ww1 part 2 and on that video go to 4:25 and see the tank is very similar
will there be V3.0 with automatic shifting?
Hi that's V4.0 LOL😂
Very interesting idea!
Did you use stud.io for the opening animation? if so, how did you get the tracks to line up so perfectly? i can not get them to link to each other when they are at an angle.
Hi Charles, I just connect a whole lot in a straight line and then I bend them around the wheels using the rotation tool. It's a bit tedious but it worked for me. 🙃
@@TechnicBrickPower Ah great, cheers!
Could you make a tutorial about how to design this sort of thing?
Hi Krzys you mean how to build this specific design or how the design gearing systems in general? I will probably create build instructions for this model if that helps. 🙃
@@TechnicBrickPower I was thinking about gearing system in general
Hi Just wondering, where did you buy all this bits? cheers.
Hi I get them either from sets I have dismantled or from bricklink (www.bricklink.com/) 🙃
rad
And what's the point of this? All it does is to make the thing cumbersome to operate and take away the fun of driving a tracked vehicle!
Hi DualDesertEagle...yes good point LOL. I just made it for the challenge of the design - it helps me learn and discover new designs.
I could answer this even easier: for the fun of it. To build something that is electro mechanical art, for the sake of advancing the art is fun. Yeah it needs a lot more power bit it's one hell of an achievement and I admire the design principles. Hi mate! for some reason I'm not getting notifications at the moment. Awesome work as ever! 👍🍺
@@carlbModels Hi Carl. Thanks for answering that question so well! Yes it's for the fun and challenge...some people don't see it that way ;)
Hi
Hi 😂
