[@mikefochtman7164]

I was thinking something similar. Need to find a way to smoothly accelerate and not try to apply full motor power all at once. Of course this would also help with the 'too powerful a motor' and once tuned, could provide incredible motion performance with minimal jerking.

@@alexandrep4913 The harder problem is deciding which edge fits against which edge. If you brute force it that's n^2, so a 1000 piece puzzle has ~4000^2 comparisons. Additionally since the data for the edge comes from the real world it'll be inexact, so each edge match will have a "certainty" associated with it. Ideally every match with the highest certainty will be correct, but that's not guaranteed, so there are harder algorithms for that. A 100% correct solution might be NP hard.

[@JThyroid]

But the machine will do it in a week instead of a month, and the next time you need to do the same thing, you can do it in half a month instead a full month. You'll need a full week to find the machine, fix anything that broke, and give it a clean and tune up. Also, it might take you a few months to get the machine to do it for you once, but if you need this thing done often enough, you'll save countless time over the long run. Maybe this machine (not necessarily the puzzle machine) will only be used once, but a future project may borrow parts of several different designs you've already made and will just have to modify the design slightly.

Hey @stuffmadehere, I work in a very advanced semiconductor fab that is nearly completely run via robots. I saw your interesting concept about belt layouts for you gantry system and wanted to offer a much more simplistic solution. You stated that your issue lies within moving the beam when it has a heavy motor attached. With the equipment I work on we have the same problem except on a much larger scale. Our masts/beams/carriages weigh thousands of pounds. Our solution to this problem, a rack and pinion system. Extremely rigid, fast, and accurate. You could very easily 3D print both the rack and pinion, attach it to a small electric motor and be able to maneuver much heavier payloads with much greater accuracy and stability compared to more traditional a traditional belt and pulley method. Plus it would be much easier to program your carriage movements without having to calculate individual motor resistance etc. Just food for thought, I love your content so very much and figured I’d offer what little bit of applicable knowledge I have on the subject to help make your life easier or possibly aid an advancement in a future project.

If you keep practicing and looking for ways to continue learning (even a tiny drop at a time), you'll eventually find that you're further ahead and more capable than you realize.

[@Gunbudder]

14:08 my old engineering firm had an internal challenge to write an algorithm that could solve a puzzle very similar to a jigsaw. the managers had to stop the tournament because no work was getting done! the only result was that our senior most tech fellow (an absolute genius) declared that solving the puzzle is "computationally complex!" He was also the only one to submit a working answer... on paper! he had spent every night for a few weeks working out an algorithm on paper in his notebook. most of us couldn't even map the problem into a solvable state or prove if it was NP hard or not. When nerd sniping goes wrong lol

[@Maric18]

it IS computationally complex :D my approach would be sort of bubble sort-ish, with a lot of heuristics. basically put down the corners first, then scan all tiles to find the edge pieces, then among the edge pieces, find the ones that fit to the corners and construct the frame. then for every piece check if its a match anywhere on the currently known-position-pieces this is made a lot harder by the non 100% matching from the pictures, since there is no absolute does it fit answer, and calculating the BEST fitting tile for a position is ... a lot harder ideally it runs in O(n^2) or O(n*m) where n is the number of pieces and m is the number of valid positions to check

[@karolrybak]

​@@Maric18 So here's my go on how I would do that: With this kind of puzzle you always have 4 sides, each can be a hole, pin or an edge. Also for each side of puzzle piece you have length of the side, and position of hole/pin. That could by x/y coords or just distance from top, depending on how the puzzle is made. It shouldn't be too hard to determine middle of hole/pin. That should allow you to create a simple comparison function to check if one side of a piece, will potentially fit with a different one. Then index data of all pieces with that information, along with detailed dimensions (or photo) of each piece. Then use flood fill algorithm starting with one of the double edge pieces. You can find all the potentially matching pieces using the index, and then find the specific one using detailed dimensions. It should get easier once you have more than one side to check for.

[@Undercoverfire]

@@karolrybak The only issue with your algo is that some of these jigsaw puzzles have diagonal sides on only some of the pieces, so you end up with rhomboid pieces and even some 'triangular' pieces (if you don't count the holes/pins). Your design probably could result in a speedup on some puzzles but on some others it would fail entirely.

[@dinamutan7637]

@@Undercoverfire an edge is just 2 sides without any holes in them. i guess you could think of it like that

[@anthonybernstein1626]

My naive approach would be to take the picture of all pieces, make them black and white, extract the sides and create multiple approximate versions (like if you’d make the “ lines thicker”). When you want to match two sides, you flip one and check if the approximate versions match (line up the images and check that there is a continuous region that is black in both), if they aren’t, you exclude them from the candidates, otherwise check the “higher resolution” versions, until you only have one. Then just identify e.g. the upper left corner, check the non-corner sides and find the matching pieces. This should be O(n^2).
