The role of positioning navigation in robots is very important, but there is a problem of bias in positioning locations. Ordinary systems cannot solve the positioning and navigation problem in robots, and the positioning results are not ideal. Therefore, this paper proposes a multi-sensor for precise positioning and navigation analysis. Firstly, the EKF algorithm is used to analyze the sensor, and the indicators are divided according to the positioning and navigation requirements to reduce them Locate distractors in navigation. Then, the EKF algorithm evaluates the robot positioning and navigation results to form a positioning navigation scheme and the positioning navigation results Conduct a comprehensive analysis. MATLAB simulation shows that under the condition of certain evaluation criteria, multi-sensor positioning and navigation accuracy and positioning navigation of robots are accurate The time is better than ordinary systems.
