Abstract: A hardware and software method, system and apparatus comprising an autonomous all weather outdoor cleaning robot designed to identify, and clean various outdoor household objects including but not limited to personal automobiles and other vehicles. The robot autonomously navigates to a designated area and scans the vehicle or object to determine the optimum cleaning routine. The robot learns its working environment by comparing scanned vehicles and outdoor objects with its existing database for future reference. The robot also compares and stores navigation data, which correlate to areas previously visited to increase efficiency for future work by reducing travel and scanning times. The Present Invention focuses on autonomous outdoor cleaning multi-purpose robots. The robots utilize microprocessors to control cleaning, navigation and perception. More specifically, the robots use multi-segmented arms to perform needful chores.
