Performing work on vertical surfaces is a difficult task for engineers who deal with
Researchers from cambridge university andToyohashi University of Technology has created a robot that consists of three water hoses, two vacuum suckers, electric motors and pumps that can climb vertical surfaces.
When moving on the wall, the robot releases the upper suction cup, pulls up and then lowers the bottom one. The device is capable of holding a weight of up to 1.7 kg and rise to a height of 4 m.
Previously, engineers from Ben-Gurion Universitycreated a robot from a wheeled device and a quadrocopter. The device has a housing with variable geometry and four screws that allow it to take off to overcome high obstacles.
