Unitree 4D LiDAR L1

Unitree 4D LiDAR L1 is the industry's first omnidirectional ultra-wide-angle bionic 4D laser radar.

Unitree 4D LiDAR L1 Features:

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 200km/h (55 m/s),the corresponding point cloud density is only 27,000points/s when traveling 1 meter (and this is in scenarios that involve personal safety)

In contrast, smal 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 auto motive-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
-------------------------------------------------------------------------------------------
Through omnidirectional ultra-wide-angle non-repetitive scanning, Li can obtain high-precision and high-density point cloud data, achieving a scan effect at the image level.

Non-repetitive static scanning
-------------------------------------------------------------------------------------------
L1 can quickly and accurately obtain the 3D structural information of the entire house, which facilitates the positioning and autonomous navigation of mobile robots. lt can also help robots expand more diverse functions such as whole-house cleaning and organization.

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 recoanition

Anti-ambient light
-------------------------------------------------------------------------------------------
Effective resistance to indoor ambient light and outdoor glare interference.

Achieve stable ranging and high accuracy map building under 100klux outdoor light.
