Gecko-inspired adhesive tape finally scales to market

The natural stickiness of gecko's feet has inspired decades-long research efforts to develop advanced adhesives. Now a company spun out of a university research group called nanoGriptech has taken the science out of the lab and into the market, through a number of newly available products promised to deliver enhanced grip and reusability.Read More

NASA scientists develop gecko-inspired astronaut anchors

Scientists at NASA's Jet Propulsion Laboratory (JPL) are honing the applications of a gecko-like gripping mechanism in the hope of making life a little less chaotic for those working aboard the International Space Station (ISS). The ever-inventive JPL workers have come up with a series of "astronaut anchors" for use both inside and outside the station, and have even equipped a robot with the tech, opening up the possibility of allowing it to safely operate on the exterior of the space station.Read More

Gecko feet inspire adhesion tech that can be turned on and off

In various types of manufacturing, parts are robotically picked and placed using graspers or suction cups. The former can damage fragile items, however, while the latter won't work in vacuums or on rough surfaces. That's why scientists from Germany's Leibniz Institute for New Materials (INM) have developed – well, a new material. It utilizes the same principle as sticky gecko feet, but its gripping quality can be switched on and off as needed. Read More

Z-Man tech allows people to climb glass like geckos

Geckos are likely better climbers than any other animal, so it's no surprise that a number of researchers have tried to copy that ability via man-made technology. One group, from Stanford University, was particularly successful with a small climbing robot known as the Stickybot. Four years ago, we heard about how they were also looking into applying the Stickybot tech to a system that would allow humans to climb up vertical surfaces. Now, DARPA has announced the first successful demonstration of that system, known as Z-Man. Read More

New-and-improved gecko-inspired adhesive sticks to more surfaces

A couple of years ago, we first heard about a gecko-inspired reusable adhesive known as Geckskin. According to its creators at the University of Massachusetts Amherst, it could be used to hang objects weighing up to 700 pounds (318 kg) on smooth surfaces such as glass. Now, however, they've announced a new version that also works on rough surfaces, like drywall and wood. Read More

DASH robot mimics cockroaches' disappearing act

Anyone who has tried to kill a cockroach knows just how difficult they can be to be to capture. Not only can they squeeze through very narrow gaps, but they can also instantly accelerate to a running speed of approximately 50 body lengths per second. Recently, biologists at the University of California, Berkeley realized that the insects have another escape skill at their disposal. When they get to the edge of a surface such as a table, they can hook it with their rear claws and swing around 180 degrees to land upside down on its underside – a maneuver also performed by geckos. A team of UC Berkeley researchers subsequently did what any of us would do upon gaining that knowledge, and set out to get a robot to perform the action.Read More

Gecko-inspired mess-free super-adhesive can stick a TV to the wall

Everyone knows geckos have extraordinary powers of adhesion, able to clamber up vertical windows with remarkable ease. With the "Geckskin", a team of scientists have replicated the effect to produce a flat, index-card sized piece of material capable of carrying a 700-pound (318-kg) load - easily enough for a flatscreen television. It can be removed with ease and leaves no unpleasant oomska. And interestingly, it doesn't work as you might think.Read More
