Description

technical field [0001] The invention relates to an accurate positioning system for an outdoor mobile robot, belonging to the technical field of mobile robot positioning. Background technique [0002] At present, robot technology has been developed and applied rapidly. For industrial robots, such as welding robots, assembly robots, painting robots, etc., are playing an increasingly important role in industrial production sites. From the development of automated production lines to unmanned workshops, industrial robots have achieved satisfactory results in technology and application. Degree. But for service robots, it is still far behind the development of industrial robots, almost still in the laboratory stage. The good news is that one of the robots, the household vacuum cleaner, has entered the application of ordinary households and formed an industrial scale. Even so, the technology of household vacuum cleaning robots has not reached a satisfactory level, and the bigges...
