Building soldiers Spider-Man suits

Everyone knows the brain-trust over at DARPA has been looking at and funding projects for Iron Man-like exoskeletons, but lets not forget about their pursuit of Spider-Man-like capabilities for troops as well.

Known as the “Z-Man” program, the Defense Department has been funding research into “biologically inspired aids” to enable soldiers to scale vertical walls in full combat gear without ropes or ladders.

Thanks to researchers at the University of Massachusetts, Amherst, DARPA has had a significant breakthrough. A “proof-of-concept” 16-square-inch sheet of “Geckskin” – named for the simple Gecko – can adhere to a vertical glass wall while supporting a static load of up to 660 pounds.

The material is an integrated adhesive of synthetic soft skin and firm tendons that enables it to “drape” over a surface to maximize contact. With a simple tug, the material separates from the surface and, like its namesake, leaves behind no wet, filmy or sticky residue.

Professor Al Crosby of the school’s Polymer Science and Engineering Department said Geckskin “literally looks like a piece of fabric with a rubber coating.”

However, the school’s Pentagon contract expired and researchers now are looking for commercial backers to further develop Geckskin, said Duncan Irschick, a member of the school’s biology department and part of the team that developed the material.

Meanwhile, most people are bound to look at Geckskin and wonder if it can be turned into a suit enabling a person to climb walls much like Peter Parker.

Irschick wouldn’t even address the question.

“Our policy is not to comment on that,” he told DefeneTech.

For now, based on photos and videos from UMass, the most practical use for the postcard-sized square is to hang a large flat-screen TV without bolts. And, hey, lets not disparage the significance of that breakthrough with football season fast approaching.

    i think it will be a revolution on combating urban terrorism. it will give a new dimension to “house entry”
    looking forward to the first display of this suit.

    Sounds like more liken Muppet labs Than Tony Stark……

  • jamesb

    fact follows fiction!

  • john moore

    Only took Iron man a few months in a desert with spare parts to build a suit hahaha

  • Papa Ray

    I would like to see this stuff tested on a pair of construction gloves. Some accidents in the construction industry and oil field are caused by items slipping from the grasp or such.

    I’m sure that others could think of other test beds and/or uses.

      No Kidding, I had someone above me on a ladder drop a screwdriver, if I hadn’t been wearing a hardhat It would have punched through my skull.

  • BackwardsBoy

    Everybody’s wearing safety glasses.

    That must be one dangerous gecko.

      Tokay Gecko’s bite hard… I mean real hard.

        In the eyes?

    I wonder what the adhesion ability would be like on a surface that is not smooth like glass but roughly textured, or what the adhesion ability would be like on a surface with tiny particulates. For example : a soldier tries to climb a wall in Afghanistan only to find that he cannot stick to the surface due to it being covered with sand particles and dust. Would the tiny “hairs” not stick the granules and slip right off? Does the surface have to be free of particulate matter?

  • Russell Romick

    Good question, it all has to do with surface contact so if the surface is real dirty it would most likely become a problem. However if you are using gloves, knee pads and boots, you could maximize the surface area contacting the surface in question.

    No mention of the F-35 this week? Come on DT, whats up? The F-35 does it’s first in- flight weapons drop on the 8th, and no article about it. Is this all I get for the weekend?
    I need more Defense Tech, then this for the weekend.

  • stephen russell

    Now they use this for the next SpiderMan or Avengers movie alone & use NO FX for close up scenes or stunts & the apps can be incredible:
    Search Rescue
    Urban firefighting
    Rescues at Sea
    IF OKs for civilian use.

    well this may just be a fail the gecko they are holding is a tokay gecko which is the skin htye want to study these arent as strong climbers as other so people wouldnt be very well supported their bones could break wih one wrong move becasue they dont have the light weight that geckos do

    • Honsu

      geckos all climb the same way and the gecko itself is just inspiration anyway

  • If you put a small piece on the dashboard of your car (or F35), you’d have a handy place to put a cup.

    That’s got to be worth a few billion dollars of research and development. They can have that idea for nothing… the non-slip cup-holder; that one’s on me.

  • Kyle

    everyone seems to think that you will be putting strain on your bones/ligaments
    where are yall getting this from. i figure if its a full suit, your hands wont be stuck to the inside of the suit. it will be tight, but not enough to cause strain. acts more like a pouch.
    just my guess.

    • Snake Oil Baron

      Yeah, a strap or two would probably be enough to redistribute the forces.

      As for pulling ones’s self up being hard on the tendons, this might be true if one only had gloves (like doing chin-ups repeatedly without practice) but add in a set of boots and you then have 3 limbs lifting your weight.

      But some kind of robot with gecko-like tank treads would probably be faster.

  • Archangel

    I personally think this may need to develop a little more

  • Jeffrey

    I always thought that that would be cool to be able to climb like a gecko and if we could make it in a glove form and also in the shoes so we could get to a snipers perch or to ushualy r un reachable on foot

  • Hi admin

    It is my great pleasure to visit your site and to take pleasure in your excellent post here. I like them very a lot. I can feel which you paid much attention to those articles, as all of them make sense and extremely informative.

    Not a bad Idea But – Is this really the type of gear needed in combat, I could see a sniper havening a use for this . I myself see a use for the average solder -It’s not a bad idea and I myself would like to see it happen but I would rather see the time and money spent on clothing / gear to stop the shrapnel or hopefully a bullet – Solders do have the body armor for upper body so find a way to help protect the hand and legs. i.e. A cloth or something in that line to help the survivability of the common problems of staying alive – this is my opinion on this .
