Unitree 4D LiDAR L2 – 360° High-Precision SLAM Sensor for Robotics & Autonomous Navigation
Next-Generation 4D LiDAR for Intelligent Robotics
The Unitree 4D LiDAR L2 is a cutting-edge laser sensing solution engineered for robot navigation, SLAM mapping, and autonomous systems. Featuring ultra-wide 360°×96° scanning and high-density point cloud output, this compact LiDAR delivers precise environmental perception for modern robotics applications.
With a built-in IMU and support for open-source SLAM algorithms (POINT-LIO), the L2 enables developers to achieve accurate localization and mapping without relying on additional sensors.
Designed for robotics engineers, AI developers, and automation integrators, the L2 combines performance, efficiency, and ease of integration—making it an ideal sensing solution for both indoor and outdoor robotic platforms.
Key Features
360° Ultra-Wide Field of View
Full 360° × 96° scanning coverage ensures complete environmental awareness with no blind spots for advanced navigation.
High-Precision Mapping
Achieves ≤2 cm measurement accuracy with dense point cloud data for reliable SLAM and obstacle detection.
High-Density Point Cloud Output
