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.

Robot equipped with hook-like claws and pendulum can climb carpeted walls
ROCR -- the Oscillating Climbing Robot -- was developed at the University of Utah by William Provancher. Its main talent is the ability to climb carpeted walls by using its hook-like claws and is powered by a motor and a pendulum tail that wings like a grandfather clock. Designed to move efficiently and in the vein of a human rock climber, ROCR is able to climb an 8-foot carpeted wall in just about 15 seconds. The team's findings will be published in Transactions on Mechatronics this month, and while future applications include possible uses as an inspection or maintenance tool, Provancher says that in the short term, ROCR will likely be used for education or as a "really cool toy." Video is below.

Cornell's switchable adhesive device keeps candy from falling, could let you dance on the ceiling (video)
Climbing walls is one of those odd feats that scientific establishments seem compelled to master -- despite there being few practical applications beyond the ultimate in Marvel-themed Halloween attire. The latest to tackle the challenge are Paul Steen and Michael Vogel from Cornell University, who have stolen the sticky-feet technique of a Floridian beetle that apparently failed to file a patent. The technique relies on the surface tension of water and capillary action of fluids forced through thousands of microscopic holes. When moisture is pushed through the holes it creates a suction on a smooth surface, enough at this point for the team's prototype to hold a weight of 30 grams. When the water is retracted the suction disappears. If all goes well, future implementations of a similar size could hold 15 pounds, meaning with enough of them you could climb a wall -- without leaving a sticky mess behind.

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]

ICM's Climber robot ready to ascend
International Climbing Machines' Climber certainly isn't the first of its kind, but we'll admit, this thing can handle some pretty daunting tasks. After successfully lasting through a number of field deployments this year, this wall climber is reportedly ready to take on the world in assignments such as "climbing the surfaces of C-5 / C-137 airplanes, decontaminating a vessel in a Nuclear Power Plant and removing paint from concrete walls for the Department Of Energy." Apparently, this iteration trumps many similar alternatives due to its ability to scale ceilings, rounded / rough surfaces and overcome obstacles that protrude up to 1-inch from a given surface. The rig can be controlled from the ground with a handheld remote, and attachments can be added for painting, cleaning, drilling or just capturing imagery from above. Mum's the word on pricing, but feel free to check out a couple more shots after the jump.[Via Gizmag]

Vortex's wall climbing robot peeks in windows
While not the first wall climbing machine we've come across, Vortex's VRAM Mobile Robot Platform (VMRP) machine weds ascension and undercover surveillance in fine fashion. Aimed at law enforcement tasks, military missions, and fanatical hobbyists, this clinger is remotely controlled with the capacity to add "onboard intelligence and sensors to monitor VMRP status and health." It utilizes a vortex vacuum to suction itself to vertical surfaces, and then relies on the wheels to get it movin'. Moreover, this bot was built to withstand mild weather hazards and communicate wirelessly back to the user, and its ability to wield microphones, video cameras, and proximity sensors make this the ultimate eavesdropping tool. Sadly, we've no idea how much it'd take to get one of these in your needy palms, but free free to indulge in the video waiting after the break.[Via OhGizmo]

City Climber rover: Spider-Man minus the drama
Sure, Spider-Man is great and all, but is all the emotional, moral and relational drama really worth it when you could just spend a few thousand on this here City Climber which does about the same thing? The robot, being developed by Jizhong Xiao and his team at the City College of New York, is targeted at New York City's mandate that requires building facades to be inspected every five years. Manual inspection usually involves suspended scaffolding and costs around $5000 a day, more than Jizhong hopes to sell his City Climber for outright. The bot clings to all sorts of surfaces using a vacuum motor to create the pressure it needs to hold on. Weighing in at 2.2 pounds, the device can carry a payload up to four times its own weight, so it shouldn't have much trouble towing along a camera or two for building inspections. By linking dual Climber modules with a hinged arm, the bot is capable of rounding 90 degree corners, or moving from a wall to the roof. Test runs should be happening this summer, spidey sense to follow next year.[Thanks, William]
