Abstract
An apparatus, system and method of operating an autonomous mobile robot having a height of at least one meter, which may include a robot body; at least two three-dimensional depth camera sensors affixed to the robot body and directed toward a major floor surface from the affixation; and a processing system for receiving of data within the field of view from the at least one three-dimensional depth camera sensor, detecting the presence of a plurality of AR tags on the upper surface of the charging base, calculating a virtual alignment point associated with the center of the robot docking connector, calculating a virtual alignment point associated with the center of the charging base docking connector, and outputting a path of travel between the center of the charging base docking connector and the center of the robot docking connector, whereby a physical connection is made.
