Completely meets the needs of small, conventional mobile robots in applications.

The top-of-the-line automotive-grade LiDAR generates a point cloud density of approximately 1.5 million points/s. At speeds of up to 200 km/h (55 m/s), the corresponding point cloud density is only 27,000 points/s when traveling 1 meter (and this is in scenarios that involve personal safety).

In contrast, small conventional mobile robots typically move at speeds far below 1 m/s. When equipped with L1 LiDAR, the corresponding point cloud density when traveling 1 meter is comparable to that of an automotive-grade system. Therefore, the point cloud density of the L1 LiDAR system is more than adequate for the needs of small and medium-sized mobile robot applications.

Dynamic scanning of the whole house
L1 can quickly and accurately obtain the 3D structural information of the entire house, which facilitates the positioning and autonomous navigation of mobile robots. It can also help robots expand more diverse functions such as whole-house cleaning and organization.
Non-repetitive static scanning
Through omnidirectional ultra-wide-angle non-repetitive scanning, L1 can obtain high-precision and high-density point cloud data, achieving a scan effect at the image level.
Close range dynamic scanning
L1 has ultra-low blind area, the minimum detection distance as low as 0.05m, easy to realize close detection and recognition
