  • I wanted to do a follow-up video going into more detail about how to work out math for simple 4 bar linkages. We use these all the time in our puppets, but the same concepts could be applied to any sort of hobby engineering or art projects.

    I’m an animatronics enthusiast. As I’m starting a new mechanical prop build, i wanted to brush up on the fundamentals of levers and linkages when I came across this video….Its undoubtedly the coolest one out there. For a moment i thought, this got to be a cool physics teacher and then I checked out your channel…no wonder you are a puppet maker/puppeteer….u designed the perfect teaching aid to explain the concept to visual learners like us

Now that we have our 3d printer and are more familiar with 3d modeling, and trying to get more comfortable with circuitpython, I'd really love to add more animatronic elements into our puppets. Loved checking out the animatronics on your channel! Did you build those?

    I started out designing a really cool folding cup holder for my van using this process. I then machined out the parts on my Bridgeport mill, it was amazing to see how much just .020 difference in pivot points would would make the difference between work perfect or jamb! Again great video!

    • @AlexAndOlmsted
      @AlexAndOlmsted  Před 8 měsíci

      That's awesome! Do you have any video of the cup holder in action?
      Yeah, those tiny little changes in pivot points change so much! Especially the closer to pivoting points get to each other. It's also amazing how much changes when you switch from a paper or wood prototype to metal, and all of a sudden the tolerances are much tighter!

    Great ideas, I didn't think those bars would be precise, but as you said - and showed - in a small region this will be sufficiently precise and more robust than belts and pulleys.

    • @AlexAndOlmsted
      @AlexAndOlmsted  Před 10 měsíci

      Thanks! Yeah, precision with paper is tricky but possible. It helps using thick cardstock to keep your paper from bending, and if you're working at a larger scale it's easier to get it closer to how you want it.

    • @esspe2
      @esspe2 Před 10 měsíci +1

      I saw this more as a prototype like Tim Hunkins showed in one of his "the secret life of ..." (linkages?) : paper and cardboard linkages are great to iterate your ideas, then you can switch to wood or metal when you get the right movement.
      And you did show a good precision with paper, eg with the opposite rotations at 19:02, that surprised me.

    So, this is maybe the third or fourth video that I watched. I love your Channel., Let me preface this by saying I love education. I love learning... but Dude! the last time I had geometry was over 40 years ago! I would gently suggest an addition to this video where you're actually applying visually, these examples to the articulation for a paper puppet. I was a good student, but bad at math., so I just suffer through it because I have to. My guess is that for a lot of Americans especially, watching, this is over their heads. We don't remember it because we literally had only one class throughout our entire education,. That could include college. Also, a lot of people don't know what a protractor is, or what it does. They assume that you eyeballed those paper circles, Andrew them free hand. Or, they don't understand what the word "fulcrum" means. I do love how you are excited by the mechanical engineering. I would just (and yes, I hate this most of the time too), "dumb it down" for us mere mortals. Still, I'm looking forward to the other of your videos that I've saved to my playlist.

    Great job. Im currently trying to find a way to reduce the torque load on a small servo motor to be able to push two tires into a turn. I started to use the shaft and steering gear plate and adding a bearing but I think the force needed would strip the gears on the motor. Easy fix with a bigger motor but I want to find the right combo of gears or levers to make a small motor move large objects. Just a matter of the number and position of levers or gears. Your presentation has given me some more ideas to test. Thanks

If you are entertaining requests during these potentially slow days, it would be cool to see this type of illustration used to show how one circle drives the other circle in a >180 degree oscillating rotation, with the driving circle making complete 360 degree unidirectional rotations. ;)

    • @sethbrandes2979
      @sethbrandes2979 Před 4 lety +1

      @@AlexAndOlmsted Now I'm trying to remember what I was thinking! LOL - I think the application I was envisioning would be to have the first perform the full 360 degree rotation in a single direction and have the second move greater than 180 degrees but less than 360 degrees. It would actually be very cool to contrast that to the second going less than 180 degrees so both practices could be observed. The applications of having the driving "wheel" rotate 360 degrees in a single direction (such as a crank or motor driven source) can be rewarding for achieving a less than 360 degree rotation of the targeted "wheel" for things like rotary oscillation and the like. I'm no math guru, but I have a feeling the application for less than vs greater than 180 degrees will require different solutions perhaps? I don't know what the solutions are, but I can picture it being a very satisfying visual experience in the manner you did for this video. :)

      Good question! I'm a self taught engineer, so other folks feel free to correct me.
      I think at 5:34 the lever on the left has more torque, and the one on the right has less. Imagine that each lever is a wrench and you're tightening a nut. The lever on the left is longer so you can apply Force further from the pivot, giving you more mechanical advantage.
      But I could be wrong!

      Hi, and welcome! Thanks for the nice comment. We've used these concepts pretty extensively in our shadow puppets, both for live shows and our short films. It's also a great way to prototype a movement that will eventually be in a 3d puppet. 4 bar linkages work especially well in automata since they restrict movement to what you want, meaning you can have a whole series of connected pieces that all animate off the same crank.

    • @AlexAndOlmsted
      @AlexAndOlmsted  Před 3 lety

      Hey, no dumb questions man! That's an interesting problem. I haven't worked with actuators too much to know how to solve this off hand. I imagine you would have a lever with the fulcrum at one end, and your 20" throw actuator attached to the lever near the fulcrum. Somewhere further up the lever would be a point that travels 60". I'm guessing it would be 3 times further from the first actuator than the first actuator is from the pivot. It's important to know that the lever is going to travel in an arc, though, and a benefit of a linear actuator is that it can move in a straight line and not take up as much space.

    if i have two circles (wheels) that i want to spin together but they're different sizes, can i do this with one bar? It's for a horse and carriage shadow puppet?

    • @AlexAndOlmsted
      @AlexAndOlmsted  Před 4 lety

      Good question! As far as I know, you cannot. Even if the bar was attached equal distances from each circle it wouldn't work. The second wheel will just pivot back and forth. Make a little cardboard mockup and you'll see why.
      I would recommend attaching a thin pulley (make one by stacking different diameter circles or use an old bobbin) to the center of each wheel and connect them with a bit of string or elastic with just a little tension. Make sure your pulleys have enough grip that the string doesn't slide though. You can glue a little strip of sandpaper on them to make them super grippy. Then you can spin the one wheel and have them both move.
      Let me know how it turns out!

      Alex and Olmsted you are most welcome. i just wanted to ask you if you know how to make automata's and you answered me before i even asked :-D how cool is that😀 where can i see some of your automata works examples?

      @@sirpfa Ha! What a coincidence. I love automata. I haven't worked on any recently but I'll look through my older stuff to see if I can find anything good. I had the honor of repairing a few pieces from the Cabaret Mechanical Theater collection in Baltimore a few years ago, which was a real treat! Do you make automata?

      Alex and Olmsted wow thats incredible. Great job👌🏻I guess someone above seating over the clouds brought us together 😀 sadly i dont but i want if possible with someone like you... iv been around it since god knows when...I just like mechanical wonders such as music boxes but automata's are peak of the mechanical wonders in my opinion.
      I have a question from you. Since you have the relative knowledge are complicating are one dimensional automatas like the ones in link below?

    I’m confused, when you were finding the tangent line, how did you determine the size of the smaller circles inside

    • @AlexAndOlmsted
      @AlexAndOlmsted  Před 10 měsíci

      For this example it doesn't really matter what size those smaller circles are, as long as they're the same on both discs. I just made them about 1/2" smaller than the discs so there would be plenty of material around the thumbtack connection points so it wouldn't tear through the edges.
      Hope that clears things up!

    What do we call a mechanismthat uses linked levers

    • @AlexAndOlmsted
      @AlexAndOlmsted  Před 3 lety

      Hmm, I think it might depend on the specific mechanism. Connecting two levels with a linkage does make a 4 bar linkage. Whatever is keeping the pivots of the two levers at a fixed distance (even if it's just the earth) acts as the fourth bar.
      Did you have a specific example in mind?

    Lose the robotic voice . It’s hard to hear clearly. If you won’t to keep the stick , change voice to a cars navigation.
