Thank you, I'm an artist looking for a new method to do storytelling. I saw a video on YT about, sand automata in a box. My heart seriously leaped. This is so informative. The possibilities on the inner build and understanding how the final character will move based on the cogs shape is brilliant.
Thanks SJ... I'm not into automata and only did this as a favour for a friend... however, if you and anyone can get some use/ideas from this, it makes my day.it,
To all I haven't thanked for their comments I apologise and offer a pathetic "global thanks". Unfortunately I do not get notification to any comments made to my TH-cam posts. I appreciate all that take the time to look and moreso that take the time to comment.
Thanks.... Unfortunately Hung, I got this out of a book... shown to me by someone else (I hate reading)... nevertheless, it is handy for anyone attempting to make some interesting kiddies toys... or complex adult ones.
@@alexkara9696 I have never seen that book and I only know these fundamental automata movements through you. To me, the teacher is more important than the author of the book! I have discovered the world of automata by accident. Last week, I bought a scroll saw I have tried to make some memorable toys for my grand child. Three days ago, I came across a wonderful work titled "Oh Deer!" of Cecilia Schiller but could not work out what is behind the torso of the deer. I greatly appreciate it if you could speculate the kind of movement that Cecilia might have used?
Sorry Hung, I am NOT into this topic and only did it as a favour for a friend because I had a laser and could reproduce it quickly. I have no idea what her topic is about or any movement you are referring to... everything I know is in the video. I do have another couple of pages provided by the same guy that I can scan when I get a chance, load it up to my cloud storage and provide the link. Might take a few days before I get a chance to do it though.
Hi Hung, If you download the PDF from this link, u.pcloud.link/publink/show?code=XZ1r7FVZftIU7AujjTyEUwHYVvwQVpnW1IRX and read the first page, you'll then know more about automata than me... good luck in your ventures.
just found this video right now.... But the reason that it isn't going very smooth is that a x-y CNC (lasercutter) can't do a perfect circle... It will always be a little off (like oval). So when you have two gears hitting each other at some point the biggest radiusses will come together an cause some 'jamming' or roughness to the movement. I found out the hard way when I was designing wooden gears that I lasered.
Nice suggestion "cboy"... I also found that the hard way. While I design in SketchUp I usually scale up and make my circles in 96 segments and arcs in 48.... then downscale to normal size... that way I minimise segmentation issues. I back end my processing with CorelDraw, and for critical items (circles) I will use the vector capabilites of Coreldraw to draw what seem to be perfect cicles (within limitations). Unfortunately in this case I bought Matthias Wandells gear generator woodgears.ca/gear/ which when passed through SketchUp dropped the segment count down and I was too lazy to manually adjust.... However, in my case just upscaling to 2x would have minimised some of the friction issues. Nevertheless thank you for your contribution... I'm sure others may get some benefit from those wise words (no, I'm not pissing in your pocket... thanks)....
@@alexkara9696 Hi, Well even if you would draw a circle out of sketchup with another program (autocad, illustrator, coreldraw...) to avoid the segmentation in sketchup, the laser cutter can not produce a perfectly round circle. To do a simple test you can cut 2 simple circles (not in skp) with center holes and line them up exactly against each other and then spin them. Then you can see how much your lasercutter or the one you cut it on is 'off'. For my gears I used the same and some other plug in also in Sketchup. True that skp isn't handling circles well and the fragmentation issue still isn't solved in it (shame). Just the two issues together make it even more bad 😊. I ended up by sanding my gears to 'round' by using a drill to spin them since I don't have a lathe. But good work. It seems there is not much to find on automaton/automata movements in a overview. The weirdly shaped wheels were mostly used to make 'complicated' moves often in combination of 2 with a double arm connection. Good example is '' lanky doodler '' Keep up the good work!
Thanks for looking Quin, and appreciate your comment... Unfortunately this was just a proof of concept in trying to demo some of the more common "automata" movements. I promised a chap several years ago that I had a diagram and I will try to laser cut it as a demo. I finally got off my arse and did it... didn't realise the effort that was required for what I thought was a "5 minute job". I'm not really into this "automata" concept, so it was just a QED, promise fulfilled and end of exercise. If anyone can get ideas then it wasn't totally wasted.
same move using a spring or not can alow a freedom over external forces like gravity or user all this look from another century and can be made more quickly from lego tecnik for kids
Good effort mate and thanks for the interesting work. Oh, and the phrase you were looking for instead of in focus is “in frame”. Take care and thanks again
Thanks Phil... I've been making hack videos for 3+years and I often try to say "in view or in viewfinder", but notice during editting, I keep saying "focus"... cant teach old dog new tricks and if I was a dog I would be 11 years old.
Sorry SW, This was done for a friend from plans he supplied. I'm no expert and unfortunately have no desire to become one... unfortunately for inspiration in 3D you'll need to seek elsewhere.
I just had the photocopy of that one page to work from... It's not so much that I'm into automata but a favour to a friend. Hopefully the video may visualise that page more clearly.
I really enjoyed watching these. I’ve been playing around with automaton. I’d really be interested in seeing how your first attempt wanted one handle to turn them off. I see from the back that each mechanism is turned by that single gear pair. How did you have them all linked together? Can anyone answer that question for me? Thanks.
Sorry for the late reply Clint... I don't get notification for all comments to my posts... it seems I only get them when the Gremlins go on sabaticals. However, to attempt to answer your question (I can't post, don't know how to, pictures), further below is a link to another jig I made that uses a combination of gears. It was a case of adjoining gears driving each other... unfortunately for only a proof of concept, I didn't bother to follow it up because of friction issues and at the time I didn't have bearings in my workshop arsenal. I have uploaded my pilot Sketchup diagram to my cloud storage at, u.pcloud.link/publink/show?code=kZGMTIVZj29C5qR6CdksfRgkwe0Xw7SdYNO7 I have also taken a few screen dumps in case you don't have access/working knowledge of SketchUp. Here is that other jig that did pass line up and got past the drawing board, th-cam.com/video/QkKrDvPFr1Y/w-d-xo.html or if you prefer a bit slower action, I wrote a covering article for Lumberjocks at, www.lumberjocks.com/showcase/how-to-make-a-50-a2-scanner-for-200.91256/ For my gears, I bought Matthias Wandel's gear generator, woodgears.ca/gear/ (Don't know what the on-line freebie offers.)
Thanks for the interest Sandi... I'm not so much into automata, short of a heart started vino when I get out of bed... A friend asked if I could make up a demo model of some of the mechanisms used for some of the basic automata movements. This is just to move from paper to timber. The laser makes it easy for me and that's why I undertook the project... however, the files should provide enough templates/ideas to make the desired action. The link provided should give access to files (PDF) that may help in design... the video just makes it visual... you still need to use imagination to make it work. Often using a mix of the mechanisms, can get some very interesting actions... said from hearsay rather than experience. I thank you for your comment... it's what makes me keep on trying (I know... very trying), to pass on what little i know or get exposed to. Sometimes it has to be in your face to come across some potentially useful info.
Nice work! There are a few videos on YT about designing cams down to like the 4th derivative which is something like the acceleration of the acceleration. A real brain twister! 🧐How did you make your cams and parts? I have a pdf of a 1898 Engineers Mechanical Movement Reference and have been toying with the idea of making something along the line of what you have right there. Great video topic! 👍 Ahh looks like you laser cut'em or cnc milled them.
Sorry Max, I'm not into automata and haven't really studied it. A friend approached me about the subject and asked if I could cut and build something something using my laser. He teaches woodworking and wanted some sort of example to show his student.... that is the limit of my knowledge about automata. Good luck in your venture.
Sorry delcat, I have regained receiving comment notifications again and being a hot head, I tend to reacted without due consideration. I started drafting out a reply thinking you were shit stirring like others have and I do tend to bite. Checked out your site and noticed that you break your presentation into short videos and decided to reword my retort. I know I tend to crap on, but as my presentations are never scripted, formulated in bed, and many times whipping down to the workshop asap to start the presentation. Because of the combined length of all the individual parts, it is often the case of re-shooting, which many times cannot be done once items are in progress/finished (I don't edit on the fly) and I hesitate in deleting too much content fearing I might remove something that may actually be useful. I have started to adopt "in part" presentations... unfortunately the major achievement from that exercise was more videos in only slightly shorted duration.

This is exactly what i was looking for, gave me a good basic on how these things work.
Me too...This stuff is Gold for making Halloween Props with a Deer or Whiper Motors...just scale up the Arms, Cams, and Wheels...
Super useful for me. Thanks for doing it!
Glad is is/was useful.
Excellent presentation. Thank you sir.
Just what I was looking for Alex - Thanks for all your efforts
Glad I was of some help... Keep safe!
Followed the link from LJ. Nice project, great presentation! Thank you for sharing!
Thanks... appreciated... keep safe.
Great work and one very interesting project. WOW!!!
Sorry I missed this Bruce... thanks for looking. I just remember making a promise to a LJ member, and amongst all my foibles, I try to keep promises.
Very nice, I learned something. That's a lot of work indeed. Thank you.
Putting nylon or Teflon washers would possibly help smooth things out?
Dusting with graphite would be another dry lube perhaps?

I'm just starting to research automata, so your video and the file you shared are so very helpful. Thank you!
Pleasure!

Thanks Alex this is just what i was looking for to teach my students
The problem with example D is its extended all the way out. Had it done slack left in its stride it wouldn't double back
Very well done!
Same for paper engineering, Origami, and other movements... basically same except for order.

You could use bearings and wax for the gears and maybe change the gear ratio so that both gears are the same size.

I'm guessing that the gentleman he refers to meant that these 10 movements can cover all of the motions that go into making automata.
