Yes! Here is an example of a living hinge on thingiverse [www.thingiverse.com]

Many of FDavies' projects [www.thingiverse.com] use all sorts of cool compliant flexures for bearing mounts and such. Technically a compliant flexure is not a "living hinge" but it is close enough to deserve mention.

And also (shameless self-promotion) I have done some work on compliant devices [www.reprap.org] that might work well with laminated cardboard construction.

Living Hinge

The second video I could see using it for mars landers and such instead of wheels, the only major drawback is the use of vacuum energy as this is the single most inefficient way to power things I can think of. The wheel looks really cute, but they probably didn't show you the other end of the pipes connected through the wall to the enormous compressor room!

I seem to recall that there was a material that did the same thing but with electricity. It was oil based and was considered for use in active suspension and also viscous couplings in transmission / 4 wheel drive vehicles. This was years back and was demonstrated on Tomorrows World in the UK (Yes I am that old!)

Google electro viscous fluid for more details.]]> martinprice2004 Delta Machines Tue, 26 Oct 2010 17:44:23 -0400 https://reprap.org/forum/read.php?178,64851,64851#msg-64851 https://reprap.org/forum/read.php?178,64851,64851#msg-64851 hackaday.com]
