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...
