AUTOMATED FAULT DIAGNOSIS AND RECOVERY OF MACHINES

A system and method for diagnosing and recovering from faults in a robot includes providing markers affixed to a floor surface, where each marker has a positional indicia thereon, navigating an area by the robot using the markers, acquiring the positional indicia on at least one marker, processing the acquired positional indicia to determine a position and angle of the at least one marker, computing a position offset and angle offset of markers with respect to a reference position and angle, adjusting the reference position and angle when the computed position offset and angle offset meets a first predetermined criteria, and alerting an external entity when the computed position offset and angle offset does not meet the first predetermined criteria.
