NASA's Astronaut Glove Design Competition

FleaPlus writes "NASA's Centennial Challenges program has announced its latest prize contest, the Astronaut Glove Challenge. The competition, a collaboration between NASA and the non-profit Volanz Aerospace, will be held in late 2006 and will award $250K to the team which produces the best-performing glove within contest parameters. The basic idea was originally proposed last year on Rand Simberg's Transterrestrial Musings blog to improve on current gloves, which have difficulties with remaining flexible while maintaining constant internal pressure in the vacuum of space. Previously-announced competitions include prizes for superstrong tethers, beaming power, and extracting oxygen from lunar regolith. These prizes are intended to lay the groundwork for larger competitions to further NASA's Vision for Space Exploration, possibly including 'an eight-figure prize for the first privately developed robotic moon lander.'"

    Authors:

    Abstract
    The sucess of astronauts performing extravehicular activity (EVA) on orbit is highly dependent upon the performance of their spacesuit gloves.A study has recently been conducted to advance the development and manufacture of spacesuit gloves. The process replaces the manual techniques of spacesuit glove manufacture by utilizing emerging technologies such as laser scanning, Computer Aided Design (CAD), computer generated two-dimensional patterns from three-dimensionl surfaces, rapid prototyping technology, and laser cutting of materials, to manufacture the new gloves. Results of the program indicate that the baseline process will not increase the cost of the gloves as compared to the existing styles, and in production, may reduce the cost of the gloves. perhaps the most important outcome of the Laserscan process is that greater accuracy and design control can be realized. Greater accuracy was achieved in the baseline anthropometric measurement and CAD data measurement which subsequently improved the design feature. This effectively enhances glove performance through better fit and comfort.

    After I made the submission, I came across the following bit on Space Politics, which I think gives a better context for the competition:

    Since Michael Griffin became NASA administrator a few months ago we have seen a gradual change in the agency's position on the role of commercial entities in carrying out the VSE. Griffin initially said he was open to it, but noted in early May that he did not want to get into a position where the agency had to rely on commercial contracts to carry out the vision: "I cannot put public money at risk depending on a commercial provider to be in my critical path." Last month, Griffin said he wanted to press ahead with commercial ISS resupply services--cargo initially, later extending to crews--to free up resources elsewhere.

    Yesterday, though, NASA raised its commitment to commercialization even higher. Speaking at the Return to the Moon conference, NASA's Chris Shank made it very clear: "We've run the budget and we can't afford to do this with a traditional approach." A non-traditional approach, he explained, will put a far greater emphasis on commercialization, including ISS crew and cargo and perhaps other opportunities, such as purchasing launch services for the CEV. Later in the day, NASA's Brant Sponberg unveiled the agency's new Innovative Programs effort, which includes a mix of service procurements, other transaction authority, and prize competitions.


    I also rather liked this bit on Clark Lindsey's RLV News:

    Jim Muncy gave a brief but interesting summary yesterday of how he sees the situation with US space policy. He saw Shank's presentation as an indication that the long battle by the entrepreneurial space community to get commercial spaceflight companies welcomed as partners in space development has been won. However, winning a battle can actually mean tougher consequences than losing since now comes the challenge is to fulfill that partnership successfully.

    Getting another "big idea" accepted is also making progress. Large scale space settlement must become the primary goal of the space program. No Antarctica-like outposts on the Moon but Las Vegas-es instead. Griffin, in fact, stated in testimony to Congress that human expansion into the solar system is his long term vision for space policy. However, this big idea is still foreign to many at NASA, in Congress, the press and the general public.

      The gloves have to be able to maintain some pressure, and be flexible at the same time. It's a bit like having a flexible balloon. The air pressure inside tends to keep it in one shape, and it resists being bent. Same problem with the gloves. Bending a digit reduces the volume inside the glove, which increases pressure, so the glove doesn't "want" to let you bend your fingers, and the glove is constantly trying to return to the shape of maximum volume, usually meaning all digts extended. This really hurts a person's dexterity, making it difficult to make a fist or grab a tool.

      What are the advantages of putting a human outside the ship rather than a robot with various tools and sensors/cameras?

      It seems like this problem of keeping the human alive and capable outside the ship is difficult. How much would we stand to lose by using a robot ball? Some people here are wondering about just shutting off the hand entirely, and just attaching mechanical arms onto the end of the hand encapsulement. Perhaps they could just eschew the human part entirely and just go with arms.

      Humans have smell, touch, taste, and sound either cut off or eliminated outside that ship. The body's design isn't really custommade for space, so it'll naturally be inefficient. The hand is an amazing tool, but there's all this trouble keeping it working the same way in space. Perhaps they should just learn from the hand's design and put out a much-simplified adaptation of it onto the robot.

      The other big bonus of having a human in space seems to be awareness. The head and eyes are quick and easy to use. But can't you just pivot cameras around, and even zoom them in more effectively than human eyes?

      Legs probably don't help that much in space, that's why I'm assuming a ball with jets on it would be how somebody'd cobble together a robot.

      The space shuttle is pressurized to 1 atmosphere 'regular' air. The space suits are pressurized to ~.5 atmosphere 100% O2. Astronauts must prebreathe oxygen before using the suits to avoid DCI.

      Interesting thing about DCI, if you briefly drop the pressure and then raise it again, your chance of ill effects is quite low. (this is one of the reasons navy divers come up quickly and jump in a deco chamber instead of using time-consuming in-water decompression) In other words, during the 10-90 seconds you could survive in the anoxic environment, it is unlikely you would get bent, even if you were rescued just in time.

      There are two things you need to consider in guessing the occurance of DCI: formation of bubbles and expansion of bubbles.

      Expansion of existing bubbles will occur according to the ratio of pressures (to a first order) for a quick change in pressure. I am not a biologist, but I would guess that your tissues themselves wouldn't reach 0psi even if exposed to vacuum: if your heart is pumping, you've at least got minimum blood pressure over hard vacuum in your tissues.

      Formation of bubbles is a bit more nebulous. It involves dissolved gas coming out of solution. It depends on the pressure in the tissue, temperature of the tissue, quantity of dissolved gas and even on the species of dissolved gas. Allegedly, oxygen is metabolized quickly enough that the quantity of dissolved gas is nearly always below the limit for the pressure+temperature.

      You can see both mechanisms by examining your favorite pint. Guinness is pressurized at about 2.5 ata iirc. Upon pouring, due to the lower pressure, some gas comes out of solution very quickly (but the dissolved gas in a pint of guinness remains greater than room-temperature would allow for quite some time: at least duration of the drinking). Some gas is released over time as you drink it and if you follow the bubbles from the bottom to the top, you can watch them expand and rise faster. (after initial pouring, there is a convection cell which is irrelevant to this discussion but produces the interesting effect, "Wow! The bubbles go Down!") Finally, when you pour the ale down your throat, the rapid temperature change forces more of those magnificent bubbles out of solution.

      Incidentally, I fail to see why people believe you would struggle for breath if exposed to vacuum. It's true you wouldn't be getting enough oxygen, but unlike an asthmatic, you would meet no resistance to the expansion of your lungs. just nothing would be there filling it. I assume that means you would breathe normally or possibly try to hyperventilate. I'm not sure about this though: hard vacuum would be pretty good at transporting carbon dioxide, accumulation of which is the trigger for breathing. There is no reason to assume pained struggling for breath.

  32. why glove by mattr · · Score: 4, Interesting

    At the risk of sounding silly and with my hubris level ratched up real high? I'd like to suggest a couple alternatives which might be combined.

    1. Mittens (less work I think per finger, more room for heating/cooling lines, less fabric and surface area). Also, enough surface area to be able to bind magnetically to tools maybe, and everyone knows mittens are warmer.

    2. Robotic waldo claws, titanium and plastic hand simulacra and radical tentacles (as another poster also recommended waldos). Keeping the hand inside the end of the arm with a metal/rubber waldo attached to the outside (making your arms a bit longer basically) would have some definite advantages. First, you don't have to worry about puncturing your glove, you can get more strength into the waldo than your muscles provide, no pressure to work against, could be controlled by someone else, you could have more than two waldos coming out of your suit (either you multitask between them or you get someone to operate others), they could be shaped like tentacles or wrenches or whatever is best for space work, you can use materials best for space work without having to worry about bendability, temperature, or radiation protection, and you can use very thin or tiny waldo elements scaled down from your hand for tiny places, with mechanical aids adding precision (i.e. lock to an axis, etc.). Finally, consider that while you could just imagine having a single metal hand stuck at the end of a lengthened arm, looking like a deep sea diver's suit, it is also possible to imagine a plasticine hand virtually identical to that of man, but made with titanium bones and superplastic muscles. Considering that evolution and our brains have gotten this far with the current design, it may be best to simply use the same design but beef it up for outer space. If well integrated with the astronaut with advanced haptics technology, it could become like a "ghost hand" and very intuitive to use with fine control. Lastly, about those tentacles. Well yes, space anime does make good use of tentacles, and Doctor Octopus likes them, but I'm thinking that outer space might indeed be like the deep sea in that a large number of highly deformable tentacles could be extremely useful, if the mental barriers to efficient control can be overcome. Certainly it could be possible to mimic a hand with a bundle of fine tentacles, but I am mainly thinking about being able to grip and hold in place multiple large objects, hold oneself down so you don't float away when you try to screw something down, etc. If you could imagine yourself to be more of a fanciful creature from the undersea world than a landlubber biped, you might be able to imagine some improvements. Personally I like the idea of a utility tentacle that will grab onto secured parts to steady you when you are about to float away, and perhaps a couple additional ones that you can use to orient one or two parts in relation to your body while you are working on them.

    3. muscle magnification. As someone said was posted earlier which I didn't know. If you have motors in your gloves they could detect where your are trying to move it and then supply more strength. Apparently the original post mentioned nerve signal sensing though I don't know if that's necessary. Also, use of memory metal and other active materials might be useful, and maybe a glove that makes it easier to (ratchet) close than open might be possible.

    A combination of the above ideas might be useful, for example if you have a mitten and pull out the area between thumb and fingers to make it a convex box (maybe narrowing wrist to maintain pressure), you can then freely move your fingers and wrist to control a waldo. The movement of the hand could in fact be sensed by laser scanners built into the glove interior, possibly augmented if needed for precision work by having the astronaut first put on a silk glove with barcode-like patterns all over it and a non-slip interior coating.

      Well, considering they plan on spending $250K for a pair of gloves, maybe with a few billion they can even go for jeans, t-shirt, helmet and some boots, and have enough left over for lunch.

      OTOH, if they took a good look at the current state of the art in gloves currently used for driving, motorcycles, skiing, sailing, diving, and a few more disciplines, they'd likely find something 'off the shelf' that can come damn close to doing the job already. A chat with designers at the companies already making them, and they will probably get gloves that can do the job for less than a kilobuck.

  35. i was just wondering similar by subtropolis · · Score: 1

    but just for the inner glove. Have a heavy-duty sort of spandex inner glove which runs all the way up the arm inside the suit wher it attahces at the shoulder region. Then attach the outer glove at the wrist as normal but leave it unpressurized. That could improve dexterity somewhat.

    The thing i'm wondering about is heat loss. The outer glove would still be insulated, just not built to maintain pressure. But a vaccuum isn't going to be the best thing to help with that insulation, i would imagine.

    Anyone understand this better than me? We could split the $250k...

      There's only one way to directly lose heat in a vaccuum: Infrared

      The object has to get hot enough to convert some of the heat into photons. You can see heat dissapation in the visible spectrum with *really* hot objects. e.g. Lava glows, as does metal being fire tempered.

      The truth is that vaccuum is the perfect insulator because there's nothing to transfer the molecular motion to. (i.e. Heat is just the molecules bouncing very quickly.) Thankfully, humans have an inborn solution to this problem. Our skin secrets various fluids which are inteded to absorb some of the heat and carry it away. While you can't directly transfer heat outside of the spacesuit, you can lose sweats and oils. And *that* is how you keep cool. :-)

    Is it just me, or do these figures seem a little cheap? On the one hand, NASA budgets billions of dollars for these missions, but when it comes time to outsource them and have other people do all the really hard design work, they only give a tenth of what they would normally spend.
