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)

Well, I guess it figures that Brigham Young University would be the epicenter of this research - heck, they've been working on compliant devices since the 1800s, in the form of their magic underwear! 😜

I'm no engineer; I just kept thinking about fatigue. Is that something that can be handled predictably, in how the materials are produced? (i.e. the type of plastic or metal, the curing/forging process, etc). It just seems to me that all that flexing is going to wear things out eventually (although, perhaps the whole point is that "eventually" is a much longer time than it would be in a similar device produced with multiple parts). Regardless, that is mind-blowingly awesome. I'll bet we'll be seeing more and more of this sort of thing in all sorts of products.

Wow! A helicopter for a resident break in? Must be neat living next door to the Whitehouse! I mean typically the average person would be lucky to even talk in person to an officer for such a thing within 3 hours of first calling the cops to report the break-in so you gotta be knee deep in politicians and executives in the neighborhood you call home to get that kinda service....

Compliant mechanisms look like the next scientific advancement. Truly amazing, sometimes we chemically design a new material that minimizes cost, and this time someone developed a mechanism that can minimize the amount of moving parts significantly reducing cost.

coulda done well to explain how exactly that last piece is predictable, or withstands earthquake/vibrations to prevent arming. Oh well. A powerful spring detent that requries substantial intentional force would've been enough I reckon.

is it really solid titanium if it has been 3d printed? i would assume most of the flex would be coming from the layering, so this means it would need to be printed on a particular axis to achieve the desired flex. let me know your thoughts
