Sticky robots for cleaning windows
The ability to scale walls and hang off the ceiling with gecko-like ease may be within reach - for robots at least. Metin Sitti and Ozgur Unver of Carnegie Mellon University in Pittsburgh, Pennsylvania, say their new robots - a sticky-tracked wall climber and a 16-legged ceiling walker - could tackle many jobs in the home including painting ceilings and clearing cobwebs. They could also play a part in exploration, inspection, repair and even search and rescue.
