This disinfection robot can light the way to cleaner hospitals

A robot being developed by Blue Ocean Robotics uses ultraviolet light to disinfect rooms. The Danish company is targeting the product first at hospitals, where there's a high danger of patients contracting infections. In a 2011 study, the U.S. Centers for Disease Control said patients acquired 722,000 infections during treatment at health-care facilities in the U.S. that year and 75,000 of those patients died in the hospital. It's a problem that Blue Ocean hopes to resolve with its UV disinfection robot. The robot uses large ultraviolet lamps to kill bacteria.
