Why Machines That Bend Are Better

  • Compliant mechanisms have lots of advantages over traditional devices. SimpliSafe is awesome security. It's really effective, easy to use, and the price is great. Check out SimpliSafe here: https://simplisafe.com/veritasium

    I visited the Compliant Mechanisms Research group at Brigham Young University and spoke to Professor Larry Howell:

    At the above link, you can download 3D-print files to make some of the objects in the video, plus learn more about compliant mechanisms.

    What I learned about compliant mechanisms I summarize in the 8 P's of compliant mechanisms:

    1. Part count (reduced by having flexible parts instead of springs, hinges)
    2. Productions processes (many, new, different enabled by compliant designs)
    3. Price (reduced by fewer parts and different production processes)
    4. Precise Motion (no backlash, less wear, friction)
    5. Performance (no outgassing, doesn't require lubricant)
    6. Proportions (reduced through different production processes)
    7. Portability (lightweight due to simpler, reduced part count designs)
    8. Predictability (devices are reliable over a long period of time)

    I wish he included more examples for the uses of these different devices.

    If the bendy bois are made small enough to invisibly climb inside the big robots and reprogram/disable them....my money is on the bendys. An engineered robot virus.

    Larry was my Masters Thesis advisor--he is one of the great people I have known in my life. Compliant mechanisms are very cool. Thank you for posting this video-love your channel. For any who have not seen it, you should check out the Nova episode "The Origami Revolution"--which covers more BYU Compliant Mechanisms research--with origami.

    @Nathan Masters, very curious, do you guys take inspiration from biological mechanisms (i.e biomimicry)? Seems like there would be plenty of those in nature.

    No, it wasn't. More abstract stuff is better.
