Gecko-inspired water-powered robot scales glass, washes windows (sort of)
We've seen some pretty impressive Spidey-like robots in our time, but honestly, crawling walls isn't always enough to pique or interest. A robot that can scale buildings and wash windows -- now that's something to get excited about. Like this little wall climber, the gecko-inspired machine enlists the Bernoulli principle, using the flow of water through fluidic vacuum generators that allow the reptilian robot to get a grip on smooth surfaces. Next, the water is directed through a solenoid valve to a piston in the robot's spine, and finally, the excess liquid is expelled and used to get glass gleaming. Currently, the little machine is capable of carrying twice its weight, and uses a small battery to power a "wireless communication system" and the servos used to control its direction. We're definitely intrigued, but judging from the video (after the break), we're pretty sure it's no match for flesh and blood window washers.
SRI's electroadhesion tech enables new army of wall-climbing robots
When the inevitable Robot Apocalypse goes down, you can credit SRI International for helping the forces assimilate. The aforesaid entity has apparently been toiling around the clock on a technology it's calling compliant electroadhesion, and to put things simply, it gives robotic climbers the ability to scale all sorts of walls made of all sorts of materials. Tests have shown wall-gripping robots climb surfaces made of steel, brick, concrete, glass, wood and drywall, which effectively eliminates any hope of you surviving the fallout based on the construction choice of your bunker. Thankfully, it does seems as if this could also be applied to human footwear, giving Earthlings at least a fighting chance of standing toe-to-toe with these guys on the side of the Menara Kuala Lumpur. Head on past the break if you're looking for a horror film. Or a demonstrative video... same difference.
Ben-Gurion University's wall-climbing robots scale defenses, haunt nightmares, stain faux-finishes (video)
We've seen plenty of prototype mechanisms for autonomous dealies that can scale the straightest of walls, but never have we seen so many gathered together into what can only be called a festival of disconcerting feats of robotic ingenuity. One uses magnets, one has little claws, and one uses integrated hot glue guns that would leave you with no doubt that something sticky had been exploring your walls. They were all developed by a team of engineers working with Amir Shapiro at Ben-Gurion University in Israel, where he studies biomimetrics: technology that tries to do what animals do. Applications for all this? The Israeli military is apparently quite interested, a force that we will be working extra hard to stay within the good graces of from now on.
Waalbot, the wall-climbing, gecko-footed robot
Robots do all sorts of things, but climbing walls seems to be a goal engineers can't live without. Meet the Waalbot which is fitted with gecko-like micro fiber feet that can stick to vertical and ceiling surfaces. In addition, the legs are wheeled with three feet that can rotate and cruise over surface curvature and even grab onto other walls at right angles. Unlike other wall-climbing robots, this one is small and light, and given its diminutive size, capacity varies depending on the surface type and size of feet. Using a PIC microcontroller and wireless controls along with batteries, Waalbot is designed to be completely autonomous and untethered.[Via Engineering TV]
Wall-climbing robot scales nearly any building material
Most of the bots we've seen recently have either been targeted at performing human-like tasks or simply too adorable to actually fear, but SRI International's wall-climbing robot is doing its best to put some terror back in the bot game, using something called "electro-adhesion" to cling to nearly any building material and climb with surprising alacrity. Electro-adhesion is apparently relatively low-power, and SRI researchers say that the bots can even climb walls that are covered in dust or other debris. Interesting -- just don't give the thing any cameras or lasers, okay? Video after the break.
Researchers develop sticky gecko-like material
Researchers at BAE Systems' Advanced Technology Centre in Bristol seem to have take a cue from Q's play book, developing a new synthetic material that could be used to create special wall-climbing suits for soldiers and spies. The material is designed to mimic a gecko's foot, which is covered with hairs so small that they form a bond with just about anything they touch, but can still be easily peeled off. In addition to human super-hero antics, the researchers say the material could also be used for wall-climbing robots. But the Brits aren't the only geeks that have turned to geckos for inspiration. As you may remember, some peeps at Stanford recently managed to not only replicate a gecko's sticky feet, but create a full-fledged geckobot.
