An Adaptive Location Strategy of Underwater Autonomous Robot

Location system is a key technique of autonomous robot. The location system of a underwater autonomous robot is studied in this paper The robot can move in mud according to the prearranged trajectory. It is used to dig the hole in the mud underwater to place the wire rope for elevating the sunken wreck. The location system of the autonomous robot is designed. Because relative location is applied in the location system, location error of location system is accumulated with the increase of move length. Based on the theoretical analysis of the adaptive algorithm, LMS adaptive algorithm is applied to process the data of location to reduce the error of location system. The simulation results show that LMS adaptive algorithm can reduce location errors of the underwater autonomous robot effectively.
