PC World reports on an interesting tech that can let robots use electricity to climb walls.

Von Guggenberg said that the new electrical adhesive technology called compliant electroadhesion, provides an electrically controllable way to stick machines to a wall. Since positive and negative charges attract, SRI researchers induce negative charges into the wall being climbed, while at the same time imposing positive charges in the robot, using an on-board battery source.

That adhesion lets the robots, using either feet or tracks, scale a vertical wall. They can even climb walls covered in dust and debris, or made out of concrete, wood, steel, glass, drywall, and brick. However, they have a harder time with damp surfaces...
