Study on location system of underwater robot based on LMS adaptive algorithm

Adaptive algorithm is widely applied in the filed of digital signal processing. LMS adaptive algorithm is applied in the location system of an autonomous robot to increase the accuracy of the location system according to the analysis of the adaptive filter. The autonomous robot is used to dig the hole in the mud underwater along the prearranged trajectory in wreck salvage. The working condition of the robot in the mud is terrible. The location system is designed. Based on the location method, the location errors of the autonomous robot are analyzed. The LMS adaptive algorithm of location system is simulated in the computer. The simulation results show that LMS adaptive algorithm can decrease the errors of location system.
