    I received a CZcams comment from one of my CZcams channel members on another tank video which suggested building a Mobius strip tank. They didn’t really know why that’s a good idea, and I don’t either, but we’re going to build one anyway and see what happens.
    A mobius strip or loop is a one-sided object known as a non-orientable surface, meaning that within it one cannot consistently distinguish clockwise from counterclockwise turns. You can read more about this on Wikipedia, but we can easily demonstrate the principle by getting a strip of paper, putting one twist in it, and joining the ends together.
    This means that we essentially have one continuous side, so if we follow it around, we travel over what would have been both sides of the strip when it was flat, and return to where we started.

      James I have an idea! I was thinking about how to make the fastest feasible tank, I realized that the real problem is the sprocket system, what if we moved the track with magnetic fields like a maglev, with very low friction between the tank "wheels" and the track, magnetic suspension and acceleration.
      this is a very sudden idea so I just leave it here in the hopes you understand what I mean, I was literally thinking about the rocket tank the soviets made when I realized that friction is what's really keeping a tank from reaching higher speeds, wider tracks may help too im not sure.

Making it like a Möbius strip just means that both sides have to do both and hence compromises need to be made making both sides worse at both. So it would wear better and perform better just with a properly designed normal track.

    Actual uses for a mobius track:
    -If you want a machine to stamp a repeating pattern into concrete, you could make it half the size with a mobius track.
    -It will increase how long rubber grip pads will last, because they are only contacting the ground half as often.
    -You could use it for a belt in an airport, again to increase the uptime before you have to replace the rubber gripping surface.
    -You could use it to tip material off the side of a belt in a factory.
    -If you put in two twists instead of one, you could have a belt with a different surface texture for only part of it's run. Not sure why you'd need that, but it probably has a use case somewhere.

    as others in the comments have stated, it would wear both sides of the track evenly. if you put grousers on both sides (single side?) of the track, all of the grousers would wear at the same rate and the entire track would last twice as long compared to a normal two sided loop of track (that only runs on the outside).

    James!! Ive got an excellent suggestion for a possible use of the mobius strip treads: cleaning! with mobius treads you could clean debris regularly from both sides, ensuring that they cant get bogged down! Think about it, treads can now go through mud or sand or rocks. One brush per tread means that every two rotations both sides get cleaned (thinking like a bristle brush). Or for overkill, a brush on each corner would constantly clean both sides but the brushes only need be on one side. Obviously this isnt an issue for huge tanks, but for small ones it might really benefit. What do you think?

    The ideal turning position could be software controled:
    Only leave 1/3 of the mobius total length as the slippy part (just enough for one contact surface length to be full slippery if in the right position)
    When turning, software calcultes the exact slippy part of the inner turn circle to be inside and provides torque only to the outside.
    "Tank turn" unfeasible though.

    • @Nevir202
      @Nevir202 Před 6 měsíci +2

      Could be done, but you'd then need stepper motor so the controller would know where the tracks are, and to calibrate regularly incase the motors lost any steps, or the tracks slipped on their sprockets.
      But I think you've misunderstood the issue. At 12:02 he points out that in the situation where one side is slippy and the other grippy, it CAN'T turn because the grippy part just drags the whole thing forward. SO what you'd actually need to do, is make sure that if you give it a turn command, it only tries to turn when both tracks are in the same phase.

    What might be an interesting use (although a bit of an engineering challenge) is to make the twist switchable. So In normal use, you'd have non twisted tracks with either the smooth or grippy side in use. Then when you need to change grip, one of the track joins would twist on each track and allow both tracks to do one loop and effectively change their surface over.
    It wouldn't be a Mobius strip then as such, but the twist capability of the links would allow this 'flip sides' option.

Then have a free 180 pivot between that link and the one "ahead" of it.

    Also, pedantry time: a "bogie" is an assembly of two or four wheels that is independently suspended or articulated. That is, the wheels are (usually) fixed in place, but the assembly is suspended or articulated independent of the rest of the vehicle. With your design, the wheels are just fixed to the frame, so there's no bogie involved. Which means they're not "bogie wheels," they're just road wheels.

    I kind of want to see a mechanism that can deploy extra grip on tank treads with the push of a button. Maybe it can rotate a cam that pushes down on a spring loaded grip in the tread as it runs underneath?

    Suggestion: rather than using Mobius track with uncontrollable switch between rubber and slick sides, make a rigid (standard) track with rotating central part within each segment with one rubbery side and one not. I mean, that each segment may have H shape, where vertical lines are the axis, that connects it to other segments, and horizontal central axis allows perpendicular rotation of a flat part of the segment with a pad on one side. So the track will look like this: HHHHHHHH. Then you give the track no freedom of perpendicular rotation, except in the upper part of its trajectory, where you put a mechanism to overturn pads controllably, when needed.

    a twisted upper tread causes more friction which is amplified as the tank's scale increases closer to real world proportions and it may still work but it will also cause more stress on the treads. You'll also need to re-engineer the rollers to handle dirt and debris being carried into the inside of the tread.

    I guess one advantage would be for this design if the tank was running in an extremely muddy/wet environment where the effectiveness of the tread grip is compromised, you could have a brush/cleaning device within the mechanism (maybe by the bogey wheels) to clean the outer tread surface whilst the tank is in motion. Although the outer tread of most common treaded vehicles are designed to allow the tank to negotiate the terrain without cleaning.

    The advantages I can think of is that you basically have double the surface area to wear out, so the lifetimes of your tracks are extended quite a bit. It's not a lot of flashy functionality that you gain with it but cost-wise a mobius strip might have a big impact. The fact that the tracks can pivot in an extra dimension might also make your tank able to deal with even more uneven terrain than a normal track can. for example if they can twist when in contact with the ground (might have to redesign your bogey wheels for that) they might make more contact with surfaces that are tilted differently perpendicular to your track.

    It would be interesting to see a special link in the track that can spin 180 degrees, and a system that can switch it's orientation to add the Mobius effect for a single loop of the tracks, and remove the twist after that loop. This would switch which face of the tracks is used on demand, meaning you could engage or disengage the extra traction on demand rather then it switching on its own each rotation

    Interesting idea for a harvester if you think about it.
    Because what was outside becomes inside, it could be made of scoopy cutters and drop off stuff in to a wide chute out of the middle of the wheelbase to the centre of the vehicle when the tracks twist after bringing it up.. might need more action on cutting since track segments stay still when down... anything not cut gets squished.. maybe it has a purpose though.

  • @ArcAiN6
    @ArcAiN6 Před 6 měsíci

    Soooo... Just an observation...
    Instead of reprinting parts to deal with tolerances, and tensions issues, instead, design your parts with slots. This will allow you to adjust the tension without having to re-print the part again. Also, for the belt tension, again, use slots, but this time instead of completely tightening down the sprocket assembly mounting plates, put a backer on the frame, and use a set of springs to push against the sprocket assembly, this will give you dynamic tension for when going slow, or fast.
    You can also reduce the amount of "bumping" you're seeing by using sprockets with proper angled teeth. square teeth have no angular contact point to "ride" on, this will cause them to "bump" into position, knock on the flat contact planes, and bump back out. using teeth with an angled contact point will allow the contact point to continuously be in contact witht he mating surface, reducing friction, wear, and providing a smoother continuous power transfer from sprocket to tread.

    Thinking about this being used in an armored vehicle made me realize this would be horrible for going through the mud.

    you should 3d print a custom slope-rig. maybe something on a screw so that you can finely adjust the slope while doing a friction test. this would be cool because you could find the exact limit for friction, and itd be a bit more repeatable than just finding a nearby object to prop it up to some random height. and mabye you could have a tweakable first step height, so you can figure out what the largest step things can go up.

    One benefit of the Mobius track/tracks is that they can keep the wheels and sprokets driving them quite clean and decrease the amount of dirt and debre get accumulated on them while also increasing it's track life with it's full track wheel and sproket assembly increasing it's work life and decreasing it's maintenance frequency.
    Do a test of driving this tracks in mud and dirt and see how clean the tracks and track assembly stay after each run compared to a regular single side track just in comparison no need to print a single side track you can adjust this one to become a single side track for testing the two types of track assembly.

  • @badsamaritan8223
    @badsamaritan8223 Před 6 měsíci +1

    I think the issues this would create outweigh any possible benefit. At least for outdoor use. You're gonna be running the dirty side of the track over your sprockets all the time, so you're either gonna get it all jammed up with mud and rocks and crap, or worse, the rocks will derail it.
    Could be useful in a closed environment, where surface wear is greater than tension, torsion or shear forces, giving you double the surface area by using both sides of the belt.

    would be interesting to have a double twist such that along the ground you have smooth treads, then a twist to a grippy tread that could be lowered as needed, or raised when turning, then twist back to smooth again at the other end of the tank. wouldn't be a mobius then, but still a twisted tread tank

  • @drsira7248

    I think these tracks have a weirdly cool application: Fantasy/SciFi Tank!
    Because of the twist the tracks can provide vertical cover for the main tank turret etc. And in a world with better/more optimized materials, using the already existing and nessesary tracks to provide decent cover with no/minimal additional weight just seems perfectly viable. I could defenetly see this kind of tracks in worlds like Warhammer 40k, Halo or similar titels. In those world it would just be a logical solution to a obvious problems: how to give a tank more armor without adding new stuff? -> twist the tracks so they face outwards and cover the tracks width in the most crucial area.

    The way to go with Möbius tracks is to make them toggleable. A single link would be capable of twisting, creating a Möbius track. Then the tank should travel so the external track surface is exchanged with the internal one, before untwisting the link to undo the Möbius. Effectively providing two different types of treads. Real tanks already use e.g. rubber and all-metal tracks depending on the scenario, but Möbius tracks would be toggleable on demand, without stopping, the need for manual installation, tools, or extra parts. It may be possible to develop such tracks for some existing vehicles, but a futuristic tank could even switch automatically depending on the terrain it sees ahead on the trajectory chosen by the commander, or sustained damage: the problems you've noticed when turning with mixed tracks could maybe be used to undo another problem.
