Wall-climbing bot does it with ease

Paraswift is a robot that can climb vertical surfaces with ease. Here you can see the robot motoring up the side of a building with a parachute packed on it’s back for use on the way down. The team that built the robot is calling it a base jumper, but after seeing them catch the falling robot in a net we’d say it’s still a bit too fragile to make that claim.

The parachute isn’t the only way for this guy to get down after a long climb. As you can see in the video after the break, it has no trouble driving in any direction on a wall. Like other wall-climbers the Paraswift is using air to stick to the surface. A vortex of air, similar to a tornado, generates a large amount of negative pressure, sucking the body of the robot to the surface it is climbing. I you’re the one who traded a good portion of your life to spend building the Paraswift we’re guessing you added the parachute to hedge your bets against a power failure.

Wall climbing robot uses supersonic grippers

Watch out Spidey, there’s a new wall climber in town!

Researchers [Matthew Journee, XiaoQi Chen, James Robertson, Mark Jermy, and Mathieu Sellier] recently unveiled their wall climbing wonder bot at the 2011 IEEE International Conference on Robotics and Automation. Like most other wall climbing bots, theirs operates on the Bernoulli principle to keep it stuck to the surface, but that’s where the similarities end.

Unlike other Bernoulli-based climbers, this robot’s gripper never actually touches the surface it is climbing. The researchers were able to accomplish this feat by designing a specialized gripper which forces air through a 25 μm gap, creating a very powerful low pressure vortex. The gripper’s design compresses the air by shape alone, causing the air flow to reach speeds of Mach 3, without relying on powerful pumps or increased air volume.

The researchers state that their supersonic gripper can support about five times the weight of a conventional Bernoulli gripper, and as you can see in the video below it also has no problem climbing a wide variety of surfaces.
