LiDAR-based positioning and navigation technology for container loading robot

Abstract

The container loading robot lacks feature information in the open environment outside the container to obtain accurate positioning information, so a LiDAR-based positioning and navigation method for the container loading robot is proposed. By arranging several reflectors outside the container, the robot's accurate positioning is obtained by using the strong reflective property of reflectors and the three-sided positioning principle of LiDAR; in addition, the container outline is scanned by LiDAR to get the accurate position of the container relative to the robot, which provides the navigation path for the container loading robot. The experimental results show that the robot can obtain accurate positioning information when there are reflectors, and the robot's navigation path can be obtained according to the container outline when there are no reflectors, which can meet the robot's positioning and navigation requirements.
