I would want one. A fidget board that shows compliant mechanisms sounds like the ultimate nerd gift.

[@wilsoncalhoun]

1:36 Whhaaat? Are you implying that your cat would knowingly lie about having been fed in order to get more food than it really needs? Scandalous.

[@AmyMakesStuff]

🤣

[@wolfgangreichl3361]

I'm pretty sure the cat merely truthfully states that she's just moments away from dying of starvation - ... without being too specific about the exact number of moments.

[@oxtoolco]

Excellent video! Cheers, Tom

[@XYZAidan]

Amazing work on this, especially the gripper!! Really blown away by the detail you put into all of these mechanisms

[@pinethetree]

The Festo inspired mechanism at around the three minute mark is just awesome. Also thank you for the 3D files; I can't wait to make one of these.

[@saiello2061]

I believe these are called "compliant" mechanisms. I only just discovered them as a "thing", opens up a whole world of creative possibilities...! 👍 Love those mechanisms, gives you a unique feeling of saisfaction playing with them... 😁

[@DannoHung]

Are all flexible mechanism compliant? It seems at least a few differ significantly from the the previous examples I've seen demonstrated.

[@saiello2061]

@@DannoHung There must be a strict definition that I'm not aware of but I think any mechanism whose function relies on the bending properties of a material for its working as opposed to traditional linkages could be characterised as 'compliant'.

[@dan339dan]

I believe compliant mechanisms can't have friction come into play. So unless the mechanism is only powered by tensile forces, it's not compliant. At least that's what I get from compliant mechanism videos

[@jaimemitchell3928]

Amy, I used your Honda Element shelf design and it made my home really comfy and functional. My instructor just recommended this video for our laser cutting class. Thanks for all these great videos and designs! :)

[@AmyMakesStuff]

It’s really wonderful to hear stuff like this, thanks for sharing :)

[@LimitedWard]

Okay I've only seen one video so far, and I can tell your channel is gonna pop off.

[@dBradbury]

So many of those mechanisms are just so satisfying to see and hear in action. Thanks for sharing!

[@karthick86c]

As someone who adores flexures, I am very impressed by the amount of work you have put into making this video. Good job!

[@cushte4996]

I was just thinking today, that i havent seen any recent uploads from Amy makes stuff. Thanks Amy!!!!

Fun watching your videos. I am enjoying your thought process.

[@zirgaoec3784]

Goddamn genius. Nothing else to say really, your channel deserves to get more recognition

[@thisisridiculous337]

That is so cool! All of it! I have a tendency to overthink, watching simple solutions always feels eye opening.

[@pietrotentor7548]

the people who put not like don't understand how much beautiful are those mechanisms and well done

[@ShellingtonLabs]

This is wonderful. I like the idea of having a neat set of references readily available and nearby.

[@sgtrock68]

Yes, satisfying stuff. There's a bunch of short YT videos, I always have to hunt for when the subject comes up, where they demonstrate many different gear n linkage set ups, rotation to linear, driving an armature to follow a set path that's not circular and not simple reciprocating, things like that. Very satisfying and useful too. I needed a weird movement in a project and just could not think of a reasonable way to make to happen, but I knew somewhere in all those machine motion videos there would be something to spark the answer, and it did. Your detent mech is one I've used. Humm I should finish that project I guess...it's only been 5 years. Thanks. Cool video.

[@lfmtube]

Excellent video. Inspires me and gave me an idea on how to solve a mechanical problem with a prototype. Thanks!

[@Mukeshmiktecrep]

Those snug fitted slotted machines are so satisfying when they click and hold position

[@mikej9062]

Really neat I wish there was such a video for wooden mechanisms -- lots of these rely on material plasticity but they are still cool

[@jaro6985]

So much better than the stuff AVE tried to make. Didn't know counterbore was possible.

[@isaacsmith1653]

Glad you came across my feed! Love to see good creators suggested

[@himselfe]

Glad KZbin decided to start recommending more videos about compliant mechanisms, because I would have missed this video otherwise. You have a really humble and informative style, and I think it's great! Would love to see more videos about compliant mechanisms, so have a sub from me!

[@kadenzxc]

I love this! I've been neglecting flexures in a lot of my own stuff, and they would really be great additions in a lot of places. I subscribed because of this video. I really want to apply this with water jet cutting on steel. The butterfly torsion spring is my favorite and it would be really useful to me in steel, which is strong and can stay strong for billions of load cycles.

[@godetaalibaba2522]

That's some really cool mechanisms, I'd love to learn how to make and use stuff like that to solve any kind of problems 👌

[@andrewjmark100]

Great job show casing all of this I didn't know this kind of work was possible on a laser cutter.

[@mohe81]

Very cool demo board! I should really use flexure mechanisms more. Not only do they work great for a surprisingly long time, they also make pretty nice designs.

[@Tech_Marauder]

I mean that gripper at the end could be a single part by utilizing flexures more

[@adisharr]

Nice demo Amy, nice to see all these different types in action. Looks like quite a few can be 3D printed as well although they might not hold up as well.

[@johnjackson9767]

As someone who's getting more into mechanics, this is awesome. Thanks!

[@alechart462]

I don't know how this channel has slipped my knowledge for so long, and I freaking LOVE the content this time especially; Yes, PLEASE make a kit available in some way, even if you simply provide the STL's for the gripper, I'm interested in making it smaller but that design is so ingenious! I know several things have been coming up using similar methods, but for a 3d-printed take on the topic, it fits perfectly I think. Anyways, hoping you share or something similar! Subscribed.

[@evanjrowley]

This is really impressive. Thank you so much for sharing! 1/16" acetal is the material I laser cut the most, but I haven't ever tried making any mechanisms like this. Your work is brilliant!

[@srtcsb]

I would definitely buy a gripper kit. This is an excellent design, and I could use it for model making and other tasks. Looking forward to more videos like this. Thank you.

Countersink* Counterbores have flat bottoms

I’m just etching a solid circle, so I think I can count it as a counterbore in this case!

[@joshplayseve]

@@AmyMakesStuff Oh okay, you're definitely right. My eyes are just bad. Also I love your videos! You're incredible.

[@AmyMakesStuff]

@@joshplayseve I DO think cutting countersinks with a laser, maybe by etching successively smaller concentric solid circles, or maybe rastering a circle with a gradient from white to black in the center, would be super slick!

I need this kit in my life!! Would buy for sure (also your cat food mechanism neatly solves a common problem in my household) I need!

[@recklessroges]

I wonder how many duty cycles each of those mechanisms have until they break. Is it more than spring steel?

[@1alphasam]

Think compliant mechanisms can handle quite a bit

[@MurphyBaby]

Compliant mechanisms aren't necessarily made of plastic, so they could be a lot more durable than spring steel, because they don't have to deal with a lot of friction

[@gustavgnoettgen]

Depends not only on the design but also on the use itself - steel might bend or break easier under certain circumstances.

[@kadenzxc]

The actual answer is that it depends on the material, the shape, and the load. If you pick a material like plastic, the strength eventually goes down to zero with more cycles. For most plastic parts like this, 10,000 cycles is a decent ball-park, but the real answer comes from charts and equations. If you pick a material like steel, it can actually survive for infinite cycles. The strength goes down from the first billion or so, but it levels out to a constant "fatigue strength." If you over-design the parts, even plastic can last for billions of cycles, but the best material would definitely be a spring steel or titanium alloy.

[@AmyMakesStuff]

A lot of great answers here already! For plastic flexures, I like to design it so that they are bent only temporarily in use. When plastic is constantly subject to a force, it will creep and take the new shape. Laser cut plastic flexures can also have worse performance than you might calculate from the plastic’s material properties because the heat from the laser can create additional defects on the cut surface.

I watched for 40sec and I clicked the bell. This is awesome.

[@glennmccall2273]

Great job with this! I have found that annealing some plastics in an oven after laser cutting increase its resilience to brittle fracture, actually eliminates it in fact. If you are ever ever looking for someone to help bounce ideas off of for mass production or design for manufacture feel free to reach out to me. I have over 13 years in plastics component design and manufacturing and am looking to broaden my side project reach and network.
