Wall Climbing Robots

There have been several posts over the past year about engineering innovations that have enabled robots to scale vertical surfaces. These have generally required the use of adhesives or suction pads. This newly launched robot, however, relies on the same principle that makes it possible to stick balloons to a wall. By generating an electrostatic charge from an onboard power supply, the robot is able to adhere to vertical surfaces, enabling it to scale walls. How long before those little security cameras in the corners of rooms stop being fixed to the wall, but start following us around? Could this principle be used to make gloves that enable us to climb up walls too?

Here are some other robots that use different techniques.
