Really bad for the tracks tho right
Hi JJ yes you’ve reminded me of something I forgot to add!
It’s ok if you were just driving about on a slippy surface but not doing what I’ve done here! They didn’t break but I’m sure it will have stressed them(maybe) They’ve always been a piece which either seem fine or just snap when you go over their tolerance so I could be ok.
@@GazRsExtremeBrickMachines I once attached tracks the way as in the video, I learned the hard way that it takes next to no effort to permanently destroy them if bent backwards. Not that the machine wasn't amazing of course.
Hey cheers! There is a certain tolerance they can take and they will be fine, I think the dual setup really lightened the load and it was light model.
But like you say once they bend a touch they’re as good as broke! I’ll find out when they go on a powerful tank soon lol :)
@@GazRsExtremeBrickMachines it depends. The more stressed they are the more rigid the wheel will be. I used one wheel like that with two normal wheels to take ground pressure, worked wonders
Yeah that was the balance! It helped this model was really light too. My original attempt overwhelmed them…
I think this is one of my favourite things you've ever built. I love the sounds, the clicking and its extremely mechanical look combined with its bobbing and lurching as it drives along. Its a really strange mix of mechanical and organic movement.
Hey there thank you so much for that! I really do appreciate the feedback :) i was unsure about this until it proved it’s worth outside! Took me by surprise!
I feel like you can get rid of a lot of the wobble by adding some idler gears in front and behind the main driving gears (on the outside), so the track bends at the same place instead of the bending point moving when you accelerate/decelerate. Would probably also help with the uneven load on the motors when it rocks back and forth.
Great build!
Hey cheers and thank you for that! That’s a really good idea too! 😀
that's an awesome idea.
I was thinking about this before I put it in the title. I wasn’t sure how to describe a tank with no inside wheels on so went with this lol :)
@@GazRsExtremeBrickMachines well, the centre Wheels between the drive gear and The Idler go by two different names depending on their setup, but the other name doesn't work as well, so: Bogieless. The other name is Road Wheels.
Gazr:the man who sacrifices his parts for science. Much respect.
😂 thank you very much too :)
I agree strongly.😁
wow that's pretty amazing. Love the terrain compliance. What would happen if you had triple tracks, and the middle one the right way for drive? For all those who say it's bad for the tracks, the load is spread over many links, so the un-hooking effect is nowhere near as strong as it would be if you had two links in your hand. Nice one Gaz! 👍🍺😎
Thank you Carl and that’s a genius idea! I need to pass these models onto you before I finish them.
That would solve the turning snagging problem these tracks cause. I’ll play about with this!
I still need to build sloth mk2 but your way! :) 🍺🍺😀
@@GazRsExtremeBrickMachines that's very kind of you to say so, you also have many other fans with ideas too. I dunno if the tracks would allow a triple anyway, it just crossed my mind that it would be stronger to have a mix. I'm no good at starting from scratch but have been known to modify a few things 🤓.
Indeed! It would work great, you could even put rubbers on the correct track whilst the other two keep the shape!
And for off roading they’ll all be doing a job! We should start an alternate Lego company! 🍺🍺
It’s bad for these technic Lego tracks only because they are assembled backward which causes the connection points to deform under the load which damages them.
This ultimately *isn't* any better than just crushing the tracks in your hand. The only reason these tracks aren't failing is because the weight of the machine isn't that high, and the load is distributed over four duplicate examples of the backwards-bending track links.
You've probably heard the expression that a chain is only as strong as its weakest link. The reason this is true because *all of the load has to go through each link.* The load doesn't get magically transported to the other end just by virtue of there being more links; each individual link has to carry all that load. If you had this setup in your hand, you could snap it in half as easily as you would two links, or maybe even easier due to the mechanical advantage provided by the longer lever arm. So, don't trick yourself into thinking that this isn't incredibly bad for the tracks.
I think this tank actually moves pretty counterintuitively, it seems to mostly be moving itself backwards along the tracks which compresses the tread in the back and the spring back from the compression moves it forward. You can see it do a little bounce back and forth as it goes. I wonder if only having a back hub or front hub would effect it.
I do agree but it worked in the real world quite well, I think because it was so light it got away with it! 800g tracks, 800g for the body :)
The way it moves and acts is unlike any other vehicle, it's so strange in many ways.
Makes me wonder about alien vehicles
Yeah it’s an odd one! Once it starts rocking it gets worse and worse! Like it’s had a few too many beers :)
seeing it going over obstacles is satisfying
Hey thank you I’m glad you like it :)
Those squishes be like "what is this thiiiing" as it just gracefully goes over them.
This is awesome! With the right funding and people working on it, this could be developed into a lot of real world applications. Anything from simple RC toys and "drones", up to bomb disposal, military recon and search and rescue.
Hey thank you very much I’m glad you like it! I was surprised at its capabilities! Built out of the right materials it could be really good :)
Awesome glass cannon! It behaves very close to actual suspension with a huge range of motion!
I wonder how much smoother it would run with a flywheel to smooth out the jerky power delivery...
Hey thank you again, it’s not down to the power delivery unfortunately. Once it starts to rock it puts a bit if stress on the tracks and sprockets and it gets clunky. If I could get a tyre to drive the tracks it would be better I think :)
I like this version more than the four wheeled one
Hey cheers me too :)
The way this thing is shaking, when it's starting to move: "Oh god, oh god, the pressure! Guys, I'm not sure I'm able to do this..." 😆
😂😂
Of course is unstoppable, it's a TANK !
Even IF just for the looks: That's a dang cool build! 👍 A pleasure to see it in action.
I could even imagine real world applications with dedicated track pieces that are designed to take some of this kind of load.
Didn't thought this would work so well! Great concept👍
Hey cheers me neither to be honest. Always nice when they work better than you first thought :)
The way this thing lurches and wobbles along is almost animal like. While it might not appear very elegant or useful, I can imagine scenarios where such a propulsion system would be desirable. For instance, in low gravity, for space exploration on very uneven surfaces where spring suspension could cause a vehicle to bounce too high, and the naturally conforming tracks would give greater traction. Or on very temperature averse terrain, where the main drive components being able to be suspended well over the surface, with tracks/treads made of extremely temperature resistant material could be beneficial and reduce the heat transfer into the core of the vehicle. There's a lot of untapped potential in a design like this.
This is awesome, always wondered if these tracks could work in this reverse format, amazing the strength they have with a little
Bit of support
Hubless Tracks must be one of the most beautiful things ive seen in a while!
Yoooo that's a nearly perfect crawler design dude!
Hey hey there cheers :) it surprised me how good it was tbh, nothing really stopped it other than a big vertical climb!
Really awesome build! Very creative!
Hi there thank you again :)
I love the cute back and forth wobble it has while driving
I'm a couple weeks late to the game, but I'm loving your video.
Now, as for what you said in the video about moving well for tracks that have no traction.
The reason is quite simple, unlike a normal tank that's using the tread on the track to move forward, your design is actually laying the track down infront of it and "driving" ontop of the track.... if that makes sense.
Look up a FAUN track way for a better idea of what I'm talking about.
I want to mention that its great that you are doing your best, replying to every comment. You clearly deserve more subs.
Thank you so much! I just had a break too so sorry for the late reply :)
That's an amazing build, but at some points it looked like the gears would slip for a few moments. I think it might help to build a tensioner using rubber bands or screw pieces to help hold the gears into the treads
It's amazing how much contact surface you get. There seems enough and not enough tension to really form a good touch on any surface
Amazing creation! Keep up the good work!
Hey there thank you very much :)
Friendly advice, the chicken wire on your chicken coop will barely slow down a fox, 16g weld mesh will stop a fox getting at your chickens though. I have rabbits and was stunned that chicken wire was so useless.
Very good at tricks going over stuff
It would have an automatic suspension system technically by the way you did it Which is pretty cool!
Dude this is so freaking cool!
Wheels in the middle of the supportive track bends are a good way to limit how far the track bends. Either the track bends all the way to a pinch without issues, or, wheel supports to limit how sharply the tracks bend are exactly what you need, whatever the purpose of a wheel free zone under the middle area of the tracks actually is. Tanks kind of already have exactly whatever benefits, other than a certain weight distribution, are had with this limited bend method.
It's like trying to reinvent the wheel by building a worse one.
1:30 imagine if the net breaks [*]
One day it will lol
Quite the obstacle course and them tracks still had almost no problems very nice. My chickens would be freakin the drone sends em running yours look chill lol
Thanks Nathan! And lol at the drone! they’re always a bit startled but tend to freeze when they see a model. Think they’re getting used to it. Who knows what they’re thinking…
Yes! You’re back making unique vehicles! 😏
Hey Gubsters! Yes it’s been awhile! I have to say I’ve enjoyed the stress free builds I’ve been doing as these vehicles give me a headache lol. I rebuilt this so many times ,I’m sure youve been there haha :)
Awesome. Very cool going over bricks.
Fantastic! Thanks for sharing
I have no words, this is crazy, couldn’t believe it actually worked so well
Hey there thank you as ever I’m glad you like it! :) yeah it really surprised me too off road, I think it’s the most capable one due to those bendy tracks!
Why Nasa isn't using something like this on the rovers is beyond me. They did Hollow tires for the moon buggies, but you'd think they'd advance enough to use spring steel on tracks for ultimate traction.
Its like its rolling out its own red carpet
I think it is a kind of good suspension. I like It!
Hey thank you! It’s a bit wobbly but works :)
Amazing, looked like it shouldn't work but it performed really well. Can't wait to see how you improve it further 👍
Hey cheers Lee! Sorry for the late reply I’ve had a break from phone screens lol. I’ll try to improve it :)
Dude that’s so awesome! I love how it has kinda track suspension where it molds over the object and just saying last vid u had 70k subs and now 72k ur growing fast won’t be long to 100k! Keep it up👍😎
Yo! Cheers Nick really appreciate it! Yeah I loved that too watching the tracks cover things! Impossible to do it that good conventionally so it has a use lol
I can’t believe how well it’s gone either! I’m someone who loves watching other youtubers and never expected this at all! The goal was 1000 subs one day 😀😀
Cool, I'm really tracking with this one! =)
This is so cool. I have recently watched scrapman do the same in scrap mechanic and I think it's such a cool concept
Oh great I’ll take a look and thank you very much :)
that is a really cool idea, the only issue I can see coming from that type of track would be worse track deterioration. So what you aught to do is make another set of tracks on either side of of the tank to reduce the strain on each of the tracks
Seriously cool design!
Do you think you could put even faster motors on it and make it a speed tank? That would be interesting, seeing the clearance get higher due to the centrifugal force!
Hey nice idea I may try this when I have time! And thank you very much :)
this is impressive, also when you said the plastic grip was impressive it was because the tracks bent over objects to maximise surface area. great design lol.
Really improved from the car model!
Hey thanks Payton! Yes definitely faired better!
Very cool idea, though it seems very limited as you can't control the radius or the springiness. Perhaps you could use the track in the normal direction, but put a big rubber tire without its inner rim inside it for a similar effect? It will probably come with a lot of challenges to keep the tire in place, but it will probably be able to handle more weight without risking damaging the parts.
That's so cool!
Thank you very much :)
Very cool ! I think that adding a gearbox made of two motors into a differential could even make this baby fly ^^
Cool backyard! I like that you raise your own chickens!
Hey thank you very much! The eggs are delicious too :)
Cooool! Would love to see more vehicles at 1:26!
Hey thank you! I’ve driven quite a few of my others over the same path :)
this is like making omni wheel with a balloon
Interesting. I'm pretty sure something very like this was considered back when they were designing the Mars Rovers. They ended up going with independently powered wheels which are a metal skeleton made of flexible horizontal struts (& no tyres) instead.
Hey cheers for that read, thanks :)
Bruh you really made a tank with anxiety the poor thing shakes so much
😂
Thats so awesome, reminds me of the airless Michelin tyres!
Hey thank you Matt! I’m glad we never used them on our cars! But I think some off road vehicles adopted the concept.
this is a really cool design but i only realized that just like the hubless car this thing has majority of its weight on 4 points
Because it’s so light the weight is fairly spread out as there’s a lot of tension in the lower middle of the tracks. it does work to a degree but I also agree with what you’re saying. :)
If it was heavy it wouldn’t work well in practice, oh cheers as well!
Really good, if this was to say be used in a rover you would have to find a way to self clear the sand/dust from the inside of the track as it would scoop up and hold debris during turning maneuvers.
Hey thank you very much! Also that could be quite a problem! Lol Nice observation :)
Very creative. This is literally so cool. The tracks have to much space to be flexible.
That garden looks like a crawler paradise 😂👍
patent this design to the army and they will aprove it
I love how it adapts to the ground so well.
By the way, how's the chainlink 4x4 doing? : )
Hey there! Yeah me too!
I always keep thinking about that but one part really gives me a headache! The steering mechanism! I would have to build quite a large one I feel to fit everything in! I will do it :)
@@GazRsExtremeBrickMachines Yeah, the steering mechanism seems complicated... you can do it!
I will give it ago :)
Thats cool !!!
Thank you very much I appreciate it :)
I don't think I need to tell you how jealous I am that you have chickens...
Haha! They produce some great eggs too! :)
I def wanna see a version 2 of this thing
This is a increadible idea
Hey thank you very much :)
Very cool!
Hey there thank you very much :)
I wish i had that much lego parts and motors... And a farm!
I wish you did too! :)
You know someone out there saw this and thought, "I could make this happen, we'd be indestructable."
That is novel. It's got awesome kinetic stuff going on at the leading part of the track, grabby & suspensioning at the same time. Continue with this! You're on to something.
Hey there thank you very much for that comment! I definitely will 😀
That funny shaking reminds me of steampunk machines. Cute
Kinda looks like a jelly truck very capable
Hey Chris thanks! It’s definitely had one too many beers!
always amazing 👍
Thank you so much Thierry, sorry for the late reply :)
Nice
Hey there cheers :)
Cool Video
Thank you Hannes appreciate it :)
The tracks are fighting for their lives
Would love to see Colin Furze build and ride on of these.
Intelligent project ☺️☺️
That tracks system trades off incredible offfroading performance for reliability and versitality. Imagine being a war machine on the field and one of tracks break lolz (which WILL happen)
Hmm yes there may be a problem there! Lol
That looks epic
Hey there thank you very much :)
this looks like a mini bomb car that would transport the bomb to the enemy in some amr game
It's like " you know what, frick you gravity and physics"
This reminds me of a strider walking on water.
I love about how cute he moving
Hey thank you :)
Damn that's very good I like it
Hey there thank you very much, appreciate it :)
Genius !!
interesting design though I definitely wouldn't trust those weak track clips to carry anything heavier. definitely a cool concept for some kind of cheap springless suspension in a science fiction story!
unique design 👍 it is very good and it also work very nice !
Hi there thank you for that :)
This will take over the world with its unstoppableness
CHANGE MY MIND
This project is best rovers
These tracks can be usefull for rovers that will send on Rocky planets
Good job 👍
Some improvement required on these tracks
Awesome tracks
Hey there thank you for that, appreciate it :)
Ok but why it's doing so insanely well
Cool how it also acts as suspension.
Hey thank you! It worked out better than I thought :)
That’s so awesome!! Very genius idea! But how in the world does that work😂 I feel like it should just fall over! Amazing video as always, keep it up!
Haha cheers Easton i appreciate it! This one did surprise me, I expected far worse performance😂
That's so cool
Cheers Jacob :)
Genius!!!👏🏽👏🏽👏🏽
Cheers Pedro appreciate it :)
car: weeeeeee
chicken n hens:??????????
Excellent content and a neat build. Have you considered VEX Robotics instead of the Lego Mindstorm?
