Design and Implementation of an Epidemic Prevention Sanitizer Robot

Based on ROS, this paper studies the key technologies of epidemic prevention sanitize robots, proposes the software and hardware architecture of epidemic prevention sanitize robots, and studies the map construction, positioning and navigation technologies based on SLAM technology. In order to improve the accuracy of algorithm mapping and positioning, the Cartographer SLAM algorithm is used to complete the construction of the environment map. The A* algorithm is improved, and the Hybrid A* algorithm is used to improve the efficiency of road path planning. The algorithm is verified in the school environment, and the results show that the robot mapping and positioning accuracy is improved by 27%, which can meet the needs of complex environments such as schools and hospitals.
