SmartPlanet: With electro-adhesion, robots can scale walls [video]

Robotic wall climbers assigned to military surveillance? Harsha Prahlad has developed a smart technology called electro-adhesion. The way it works, mechanical robots are clamped to walls using an electro-static charge and then the robots move up and down with an electric power supply. Prahlad believes the technology could be used for a wide range of applications, from toys, to military surveillance to even hanging a flat screen television on the wall.
