Unitree 4D LiDAR L1
4D LiDAR L1
The Unitree 4D LiDAR L1 is an omnidirectional, ultra-wide-angle bio-inspired 4D LiDAR with a 360°×90° field of view. It features a near-field blind zone of less than 0.05m, a maximum range of 30m at 90% reflectivity, a point frequency of up to 21600 points/sec, and weighs only 230g. Built-in IMU support enables open-source odometry and mapping solutions based on the L1, available in two versions: L1 PM and L1 RM.

Features
Features
Omnidirectional Ultra-Wide-Angle Bionic 4D LiDAR: Delivers omnidirectional ultra-wide scanning with minimal blind spots and stable operation, enabling limitless scenarios.
Replace traditional LiDAR-based perception solutions: achieve the same perception performance while significantly reducing solution costs.
Open-source SLAM solution: Odometry and mapping based on L1, using only the L1 sensor and its built-in IMU without other positioning sensors.
Fully meets the requirements of small-scale conventional mobile robot scenarios: small robots typically move at speeds well below 1 m/s, and L1's point cloud density is matched accordingly.
Ultra-low blind zone: Minimum detection distance as low as 0.05m for close-range identification; stable ranging performance even under intense outdoor sunlight at 100Klux.
