In Pictures: The year in madly cool robots

A camera mounted on a mobile robot-like structure moves across Pablo Picasso's 'Guernica' painting at the Reina Sofia Museum in Madrid. Experts have long been concerned about the health of Picasso's "Guernica," one of the world's most iconic paintings but one which is diagnosed as extremely delicate after a hectic life. A mobile, robot-like structure, using advanced infrared and ultraviolet photographic technology, is taking thousands of microscopic shots of the painting to allow analysts to penetrate the work like never before and see its real condition.
