Unitree L2 4D Laser Radar (4D LiDAR), 360°×96° FOV, 30m@90%, 128k/64k pts/s, 4.5mm, ±2cm, ENET/TTL UART

Overview

Unitree 4D LiDAR L2 is a 4D Laser Radar designed for precise navigation, mapping, and obstacle avoidance. It delivers high-density non‑repetitive scanning with a 360° × 96° field of view, long-range detection, and stable operation indoors and outdoors, while remaining compact and power efficient.

Key Features

• Ultra-wide 360° × 96° FOV with omnidirectional, non-repetitive scanning for comprehensive depth perception.
• Long range: 30m @90% reflectivity; near blind spot 0.05m. Distance resolution 4.5mm; measurement accuracy ±2cm.
• High throughput: 128000 points/s sampling frequency and 64000 points/s effective frequency; 5.55Hz circumferential (customizable) and 216Hz vertical scanning.
• Safety and robustness: Class 1 eye-safe laser (IEC60825-1:2014) with >100Klux anti-glare capability for strong ambient light.
• Interfaces and data: ENET UDP/TTL UART; outputs 3D position + 1D grayscale (supports 2D mode).
• Low-load architecture: Non-contact brushless rotating mirror scanning with extremely low data reception/processing CPU consumption.
• Integrated IMU: 3-axis acceleration + 3-axis gyroscope.
• Compact and efficient: 75×75×65mm, 230g, 10W typical power (peak 13W).
• Software and integration: Supports ROS1/ROS2/WINDOWS, with open-source SLAM solutions, SDK documentation, and technical assistance.
