LiDAR, which is considered to be the “intelligent eye” of robots, has played a huge role in realizing the autonomous localization and navigation of robots. It can help robots understand the surrounding environment information in unfamiliar environments, and provide good environmental cognition capabilities for subsequent localization and navigation. Although a variety of sensors are involved in the autonomous movement of robots, LiDAR plays a greater role than ultrasonic, visual, infrared, and other sensors. The LiDAR sensor has the advantages of high resolution, strong anti-interference ability, and fast response speed.

Take the RPlidar A3 of SLAMTEC as an example, the RPlidar A3 is currently the LiDAR with the highest sampling frequency and the widest-ranging range among triangular-ranging LiDAR. It has a high-speed laser ranging sampling capability of up to 16,000 times per second. It is also equipped with the unique opto-magnetic fusion (OPTMAG) patented technology of SLAMTEC, which overcomes the life limit of traditional LiDAR and can run reliably and stably for a long time. At the same time, it can also perform 360-degree omnidirectional laser ranging scanning within a radius of 25 meters on a two-dimensional plane, and generate planar point cloud map information of the space in which it is located. This cloud map information can be used in practical applications such as map mapping, robot localization and navigation, and object/environment modeling.

In addition, RPlidar A3 can not only exert extremely high stability indoors but also has an outdoor working mode. In this mode, RPlidar A3 has a more reliable ability to resist sunlight interference. When detecting black and white objects, long-distance objects, and objects exposed to strong light, the ranging performance is more stable, and the problem can be completely solved within 10-20 meters. The application range can be extended. Expand to more commercial and even industrial scenarios.

A3 is also very capable of detecting black objects (yellow frame), as shown in the figure below:

Generally speaking, the RPlidar A3 of SLAMTEC has more obvious advantages than the same type of LiDAR, and it is also the most widely used LiDAR in the autonomous localization and navigation of robots.
