SLAM is a solution that allows robots to be precisely positioned. The robot knows its position and can plan based on the existing position. SLAM enables the computer to construct a three-dimensional model by scanning in a completely unfamiliar situation. (For applications such as sweeping robots, first model the space scene, and then determine whether to complete a cleaning)
