Two-dimensional lidar has a broad application space in the field of service robots. At present, laser mine has been applied to the field of mobile robots such as logistics robots, commercial cleaning robots, food delivery robots, etc. Especially for the emerging commercial cleaning robots in the past two years, lidar has become the standard.
Lidar is an optical remote sensing technology that acquires target-related information by detecting the scattered light characteristics of long-range targets. The resolution of lidar is much higher than that of sensors such as cameras and ultrasonic radars, and is widely used in fields such as surveying and mapping, robotics, and unmanned driving.
According to the scanning dimensions of lidar, lidar can be divided into one-dimensional lidar, two-dimensional lidar and three-dimensional lidar.

However, in the household sweeping robot market, the lidar penetration rate is lower, and the main constraint is cost. The sensors used by most sweeping robots on the market are vision cameras and ultrasonic sensors. The cost of the sensors is only a few yuan. Only a few high-end sweeping robots use lidar. The price of the two-dimensional lidar used is Hundreds to thousands.
Compared with ultrasonic sensors and visual cameras, lidar's ranging accuracy is higher and there is no accumulated error. The constructed map can be used directly for path planning and is not affected by ambient light. Therefore, lidar is more suitable for the "eyes" of sweeping robots.
