How does laser ranging work in the robotics field?

Distance detection is a key issue in mobile robot navigation. It is time for the robot to have sensors to obtain more information for the robot's positioning and autonomous navigation. Laser ranging is widely used in the autonomous navigation of mobile robots because of its long detection range and high measurement accuracy. Take the warehousing robot as an example, its operation mode is in line with the traditional E-commerce logistics center operation “people find goods, people find goods” mode. Through the operation plan, the robot is mobilized to realize the mode of finding the goods and the goods, and the entire logistics center is unmanned. The robot uses the scanning data of the external environment to determine its own posture and realize the establishment of the map. The main contents include Feature extraction, map creation, and autonomous positioning. Compared with other ranging sensors, Lidar has the characteristics of high speed and high precision. Therefore, laser radar range finder has been widely used in robot motion.
