That's so funny, for me I thought it was just an engineering student/someone with a 3d printer, this seemed far too non-abstract to be a Segerman video lol. But obviously you understand something I don't😅.
These demos remind me of the Hoberman Sphere - that spiky ball toy that expands and contracts through a bunch of linked scissor mechanisms. The Hoberman Sphere is recursive too, except there the components have a network of relationships rather than just a chain of relationships.
Commonly seen on indulgence feasts in Poland - stands with cheap (often knockoff) toys, sweets and especially indulgence obwarzanki (a very light and dry kind of ring shaped bread, no idea how it's made, availble basically only on those indulgence feasts) spring up around churches on the day of that church's patron. Usually in summer. I remember having that kind of toy, but idk if it's still somewhere around in the house.
technically you could say that it's an inverted hoberman sphere. Inversion is a geometrical transformation which (in 3d) changes planes into spheres and vice versa.
I tried to put a servo on one of the joints of a plastic Hoberman Sphere so that I could remotely expand and contract it for dramatic effect. It didn't really work as my servo didn't have enough torque. I wondered if the sphere I had relied to some extent on the flexibility of the thin plastic struts or whether a solid metal construction would also work if the joints were ball / socket.
I really want to see a machinist like This Old Tony make some of these and see if he can come up with a practical function for them, like perhaps for shelving or something. Utterly fascinating and deeply original, as always it seems. You never cease to astound me!
Seeing how the original worked, and then seeing the second one, I was actually pretty happy with myself for being able to work out how the second one would work relatively quickly. That being said, once you did confirm it, I immediately thought of trying to find a way to use these and other slightly modified racks to act as logic gates. Would be very interesting.
Love the video! If you take the first design, add a pin to the center box (attaching it to the surface below it), add another pin to the end of the left most gear rack, and a marker to the end of the right most gear rack. You will get a drawing copy machine! Love it!
I swear, this will be how certain meta-materials will work some day when we can get consistent "gears" made of bio-mechanical components/layers. I imagine this could be a great mechanism for frequency combing.

This reminds me of pantogarph mechanisms like used in various extension mechanism. Your last example in particular looks like a different take on a mechanism oft used in drafting machine, whereas the top bracket and the end unit must always stay parrallel relative to one another (so that lines remain parrallel). In these machines this was at first accomplished with a pantograph, with two rods comprising each segment of the arm. On later american machines, they switch to steel belts, which are put in tension so that they grip their respective wheels. The top and bottom disks are fixed, as is the elbow of the machine; so whatever movement is affected, the end still stays parallel. In very nice machines, the steel belt was welded in a manner as to never loose tension. Cheaper models used a belt with a tensioning nut on each band and their loosening could cause errors in the drawing. However the geared rack idea perhaps could be applied in keeping those two points fixed in a different manner. Either with solid racks around toothed gears, or perhaps with a toothed belt.
I feel like the last contraption makes an involute curve It interesting to see what kind of movement you get with only racks and gear and the application they can have
As somebody who prints and unpowders alot of your models its always great when I see them come through! Would it be possible to make a cube with recursive racks? Some thing like a Hoberman sphere or similar.
Shapeways is going to lose a lot of business now that Henry has developed the ability to magically bring parts into existence by simply pointing his finger. 😉
I'd love to see what can be done using different gear ratios between "incoming" and "outgoing" racks of each box. Would it just change the slope of the diagonal movements of adjacent boxes or can you create more complex movements using that?
Sorry made a comment twice and deleted. Thinking about this is difficult at 4am. Especially when I misinterpret the device for 6 minutes because I was typing lol. Anyway, I think if you put gears pairs into the boxes with correct ratios it should be possible? It would basically twist the path a little if you did achieve it though, shouldn't allow any more complicated movements. Though I must confess I can't think of what other movements this system can really produce.
I quite like the unique way this mechanism behaves! I think the most interesting thing about these recursive mechanisms is how it made me really look at the different reference points when figuring out how it behaved :)
You probably dont see this a a proble to solve but, You could force the first, and I thing second, recursive rack and pinion to be flat (not stair stepped) by fixing the height of each rack to a constant value based on orientation. It would require a means of selecting the height of the rack fixed to the box to 1 of 4 values, either with spacers or custom shapes for each orientation. But completely doable
10:26 this one reminds me of watching the overcomplicated windscreen wiper mechanisms on buses in late 1980s Ireland. Mesmerising and yet almost perpetually broken...
This makes me so intrigued about this idea I had years ago to make a mechanical software interface. This would be the perfect set of mechanisms to make photoshops basic transformation tools!
I think it could be a very interesting exercise to see if you could use specific combinations of these to create "linkages" that trace specific paths, similar to Fourier epicycles
As a scientist who has solved most of the problems of the world I still have to watch this video over and over again to get how it really is working. It helps to have the as real objects in the hand so one can observe the behavior. You Henry are one big genious is all I can say. Thanks 1000 times for posting this piece of art and technology.
The pure rack and pinion recursive mechanisms could absolutely work without the constant step up every iteration - if you take either version rotated to a vertical grid, the similarly orientated racks obviously never cross over each other, the horizontal grey racks never cross over with the vertical green racks, and the vertical grey racks never cross over with the horizontal green racks, so there are two separate sets of racks that could each occupy one vertical space without ever colliding with each other. That said, you would need to tweak the design slightly - I doubt you could just rearrange the parts you've already made to do that.
if sufficiently small or large it can scale pixel art within the distance that the illusion takes place. Thanks for this kind of videos Henry greetings from Venezuela
I would love to see some practical applications to these mechanisms. The parallels of the racks and of arbitrary points of the racks look like there should be ways to take advantage of it, but it is hard to envision with the video only demonstrating the simplest form of the mechanism.
It would be fun to see what kind of fun mechanisms you could come up with by making the straight racks curved. So in addition to translation you'd get also rotation.
Played with the gear cube at opensauce and found it delightful. There’s always a small surprise when it arrives perfectly cube or perfectly flat from its intermediate folded states. The “recursiveness” of these makes me wonder about how you would formulate an energy transfer equation for n segments. That exploding outro was great 😆
Of course it's very similar to the multiple scissors type reach grabber. Operate one scissors, the closing of one closes the handle of the next, etc etc. 'Scissors grabber' will turn up may of the long reach type on google..
Yes, I have also made designs based on scissor linkages. And depending on how strict you want the analogy to be, I think you could also call them recursive mechanisms.
Do you mean having a little pinion gear replaced with a part consisting of two pinions with different radius, stacked on top of each other? If so, yes, I think that would work. The box would need to be designed to match of course.
@@henryseg In my head this could lead to the final square tracing a curve not a straight line. Maybe if you stack them the right way like a Fourier sequence it could approximate any shape. In theory.
@@NathanRae If there are no rotation parts to the recursive mechanism then each rack adds a vector to the position of the next box. As you work the mechanism these vectors get scaled linearly, so I think the final answer has to be linear motion. However, there are gears with variable radius. Using them somehow could get it away from linearity.
Seems like you could have interim stages that aren't racks but are arcs of gears, with the effect that pushing the initial rack by X would push the last rack by kX, where k is some product of factors associated to the gears. If you made k
I think maybe the simplest way to do what I think you're suggesting is to replace the little spur gears in the boxes. Instead of a single spur gear that meets both racks you could have a part consisting of two spur gears of different radius, stacked on top of each other. The two racks would meet different spur gears, which would then do the usual mechanical advantage thing.
I think it's more accurate to call it vector racks, since recursion implies self-reference rather than reference to two parameters. Still quite awesome though.
Honestly my first thought when seeing this was the engineering problem of creating a 3D printer that can print a printer with a larger print volume then its own I wonder if it has enough precision for 3D printing
Ha that's hilarious. At 5:29 when you were talking about you could remove the gear as long as the box held the 2 pieces and they slid together, the first thing that popped into mind was driving them like the slotted straight driven lock/key combination shown 2 or 3 years ago in one of the lock picking videos. Then at 5:36 of course you pull out exactly that, a straight drive push gear mechanism. There's a lock based on changing the teeth of that mechanism so the matching key opens it. Fairly simple and not very secure, pretty sure they said just shoving a vegetable into it would usually open the locks. Used in Russia or Scandinavia etc for simple things like shed doors, the video showed one outside somewhere.
Would it be possible to make this system more compact by adding curling racks? that can only open to a straight angle? almost like a rolling garage door. would that be possible?
Is there any way you could make a collapsing mechanism with measured points all between both ends to move to exactly were you need them Im learning to build guitars mainly microtonal instruments and I’m trying to figure out how I can make the frets move between equal temperaments ( how many frets it takes to reach an octave ) this would normally be your standard 12 notes I was thinking 31 max and the least frets per octave would be 5 the only thing is these frets would have to move in the exact right spots while being practical enough to play maybe I could fix up a plexiglass fretboard so you see all the parts moving cool hope that makes sense
An evolution that comes to mind would be to add some sort of dampening effect using haptics design principles? In other words giving the motion a more fluid feeling by introducing slight resistance in some dimension(s). I've only just found your channel and this is the only video I've seen but will look at the others.
For this I'm referring to the rack of 7, with 3 grey boxes and 4 green. If you invert every 2 boxes and print a mirror image, couldnt you get the entire thing to lay flat, or at least not increase past a fixed limit? The first set would stagger up, but then the next one would make the following stagger down?
Something like this is definitely possible. Maybe the simplest version of this would be to bolt both racks to one side of the box rather than one above and one below. (Or rather, since they would overlap with each other in space, you'd need one L-shaped rack to bolt on.)
4:33 you buried the lede! that cube is incredible! it needs a spring and a damper so it will slowly coil (or maybe uncoil) on its own. so cool, i have to make one
Could you make each one turn 90° in the same direction to make a box and have it feed back into itself? That's what I imagined when reading "recursion".

Right, I think it should work fine. Both the expanding and the diagonal designs should be possible to close up.
This is kinda magical.

Nice! If the green boxes start in a line, they will stay on he same line. Same with the grey boxes. Cool concept :D
