A way to let soldiers scale a wall like Spider-Man

When soldiers next need to scale a concrete wall, they should leave the gecko tape at home and opt for vacuum suction pads instead.

Such a set-up, illustrated in the video below, took first place among university entries in a recent design competition sponsored by the Air Force Research Laboratory.?

The goal was to design a system that would allow a four-member team of Special Operations forces to scale buildings or mountains in a variety of conditions.?

The Personal Vacuum Assisted Climber was created by mechanical engineering students at Utah State University. Gizmag has the technical details:?

?At the heart of the two PVAC units were two back-mounted carpet extractor motors. These each created suction with a three-stage impeller, were powered by seven lithium-polymer batteries, and created a seal against the wall using connected handheld pads lined with closed-cell foam. A pressure release lever on each pad allowed it to be secured against the wall when being used by the climber to pull themselves up, then released so it could be lifted higher.?

The competition was held at an abandoned cement silo near Wright State University in Ohio. Two team members scaled the wall with the PVAC units. Once on top, they dropped a rope for the other team members to ascend with a powered winch.

The competition also pitted the three United States service academies against each other ? Air Force, Naval, and West Point.?

The Air Force Academy took top prize with a gun-launched device that would reach the top of the climbing surface and explosively set a concrete anchor for the lead rope.?

The team also developed a carbon fiber ladder, which could be used in leap-frog fashion with periodically placed wall anchors to allow a climber to scale the wall.

In the future, humans may gain for even more Spiderman-like abilities, such as climbers inspired by beetles and geckos.?For now, though, we have vacuum cleaners.
