    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: simplisafe.com/veritasium
    I visited the Compliant Mechanisms Research group at Brigham Young University and spoke to Professor Larry Howell:
    www.compliantmechanisms.byu.edu
    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)

He was right w/r/t/ the elephant's trunk, actually. It _does_ go up and in. Just that that movement happens to be cancelled by the rest of the elephant. :P As for those silicon clickety bits, does this mean we can now etch compact mechanical computers with the same techniques used to make compact electronic computers?

Mechanical systems can be much more reliable than electronic ones. I wouldn't be surprised if nuclear bombs have many mechanical devices in them. I heard of a missile that used a spring-wound gyroscope instead of motor driven. It didn't use a battery that could go bad or need to be replaced. It only needed to run for a minute or so, so using mechanical energy made since. It could be stored for years without worrying about replacing the battery.

Nah. The ones they showed were just single pieces. Like anything else you could build entire systems out of these pieces and just replace any broken parts like we already do with normal mechanical systems. Also replacements would be cheaper and easier to get - no more ordering parts and waiting for them to be delivered - just download the file (if you don't have it already) and 3D print it.

Its great to see people are starting to use flexibility as an advantage in designs (even though I personally never use it). My concern is that when using flexible materials in designs like the WMD activation device, you would have to really see how long thin pieces of whatever material they would use can last without input for years. From my experiences, when things are just sitting out, events in a temperature controlled room, they're going to degrade, plastics especially. I'm not trying to sound like an ass but that switch test is definitely flawed. Sure you can take a freshly molded/printed plastic switch and it works as he said over a million times without breaking, but that was also in an environmentally controlled room. I would like to see how well it works after going through heating and cold cycles, in different humid environments, and after just sitting for extended periods of time. If it can do all those better than traditional switches then you've got yourself a good design.

Mechanical fatigue due to repeated movement is one thing, heat cycle fatigue is another. Would like to see how it tested against conventional tools in a heat cycle environment, maybe the machine turns on and it got hot, and then turns off and cools again. Or rather cycle life in extreme temperature conditions. Very interesting video

Isn't this video kind of pointless? I mean, _of course_ machines that bend are better than machines that don't bend. It's a foregone conclusion - if I have a device that can do X, and another device that can do X + A, then the device that can do X + A wins every time. The only reason that wouldn't be so is because of cost considerations and that's not a factor here. Anyone with the functioning intelligence of a eighth grader should be able to understand this fairly readily without having to watch 13 minute long video on the matter... But then I suppose the creator wouldn't be able to keep raking in that sweet sweet ad revenue on Youtube, so there's that, I guess.
