Details

Built for indoor/outdoor robot perception, Unitree L2 delivers a 360° × 96° ultra-wide field of view and up to 30 m ranging for mapping and navigation.

High-density point clouds come from a 64,000 points/s effective point rate with 4.5 mm distance resolution for detailed environment capture.




A typical deployment mounts the sensor on a mobile robot to support omnidirectional scanning in logistics and warehousing environments.

Everything needed for installation is included: the LiDAR, cabling and adapters, mounting hardware, a rubber pad, and an L-shape hex key.
