Let the sweeping robot grow "eyes" through sensors and SLAM (synchronous positioning and mapping) algorithm. By installing sensors (laser radar or camera), the sweeping robot can monitor the surrounding environment in real time, and the data obtained by the sensors are processed by SLAM algorithm to construct an environmental map, so as to realize the global path planning of the sweeping robot. Compared with random collision sweeping robots, global planning products achieve high efficiency and full area coverage. We have a number of representative products in both laser navigation and visual navigation.
