Programmable Origami 84

Posted by kdawson from the man-who-folded-himself dept.
sciencehabit sends this snip from Science Magazine, with included video: "Researchers have created flat sheets of composite material that can fold themselves into toy boats, tents, and even paper airplanes. Based on the ancient art of origami, the sheets are edged by foil actuators — thin, solid-state motors — that contract or expand when they receive an electric current from flexible electronic circuits embedded in the sheets. After they achieve their preprogrammed shape, the sheets are held in place by tiny magnets on the edges of the fold joints. Researchers say the technology could be scaled up to create ultra-portable tripods or even cups that automatically adjust to the size of liquid being poured into them."

    As an origamist with an interest in nanotechnology, I could see a few EXTREMELY useful applications for this. I heard it said once that scientists were testing the idea that nano-switches for computer chips could be folded from nano-sheets of metal. Imagine a computer with hardware that literally reforms its self to accomplish new tasks on the fly. Given, programming it would be about the most difficult thing to accomplish, but it would still be a fun toy to play with...

      It's never ceased to amaze me how someone can create a box that maximises the number of items that can be packed, minimises wasted space (and, presumably, material used in construction), meets strength tests, and then conforms to dimensions (and/or weight) dictated by shipping requirements.

    If I had a nickel for every time I had a cup that was too big or too small for what I wanted to pour into it, I could fund the research on this project myself. Oh, and an ultra-light weight tripod!

    This will be awesome! Surely the greatest thing since sliced bread!

    • Think like a truck driver, dude. A "self-adjustable drinking cup" would make those long haul trips much faster, when the "tripod" needs an empty. Third leg 'ahoy!
    • I'd be interested to see if they could translate the movement into mobility, using it to move around. A few more iterations and you might conceivably have flapping bird wings that work, or something that could inch its way under a door before reforming into something else. I'd say this is almost more interesting than the fact of forming multiple shapes.

    This will be how we make the first self-erecting buildings of our Moon base , with no astronauts present until they are ready for occupation. Also it will be how our explorers on Mars carry their emergency shelters, for when they have to wait to be rescued after digging their rover into a sandpit.
    • I'd think a balloon would be a lot more affective and less failure prone.
      • Unfortunately, the surface of the Moon (and I guess probably Mars, too) is subject to a continuous bombardment of infalling space debris and ejecta from other impacts. So a balloon is going to get punctured.[obligatory secondary debate "but you can make it strong enough", "that makes it too heavy to transport from Earth", blah blah]

        • NASA had a Lunar building contest, the winner revealed that the lunar soil can be piled and melted with sunlight, and thus made into walls etc. The interior of such a structure will have an inflatable installed into it. This problem has already been solved, and in a much more clever fashion even than this.

  • Something about the mindless optimism of the scientists always makes me smile. They produce a sheet the size of a playing card that can slowly fold itself into a few predetermined shapes. While this is impressive, the technology is clearly miles away from tripods and auto-adjusting cups. This is a symptom of a research framework that only focuses on marketable products, and doesn't give a stuff about the actual progress being made.
