Unitree L1 The Worlds First Omnidirectional Ultra-Wide-Angle Bionic 4D LiDAR

Introducing the Unitree L1, the industry’s first bionic 4D laser radar with 360 ultra-wide-angle scanning . Designed to revolutionize mobile robotics, this cutting-edge sensor marks a bold leap into the era of intelligent mobility .

To bring high-performance robots into everyday life , Unitree Robotics has engineered the L1 with precision, speed, and adaptability in mind. Built on a foundation of technological innovation , it optimizes both performance and cost-efficiency, making advanced perception more accessible than ever.

Unitree L1 4D LiDAR Key Specs at a Glance

• 360 90 Ultra-Wide-Angle Scanning Full-environment coverage with vertical depth awareness

• Near-Zero Blind Spot Minimum detection distance: 0.05m

• Long-Range Precision Up to 30m at 90% reflectivity

• High Sampling Rate 21,600 points/sec effective frequency for smooth data flow

• Lightweight Design Only 230g, ideal for mobile platforms

• Compact Form Factor Just 757565mm, fits tight integration spaces

Optimized for Small & Mid-Sized Mobile Robots

The Unitree L1 4D LiDAR is perfectly tailored for the needs of small, conventional mobile robots delivering high-density point cloud data at speeds far below 1m/s.

By comparison, top-tier automotive-grade LiDAR systems generate up to 1.5 million points/sec, but when traveling at 200km/h (55m/s), the effective density drops to just 27,000 points/metereven in safety-critical scenarios.

Mobile robots typically operate at much slower speeds, often under 1m/s. When paired with the L1 LiDAR, they achieve a comparable point cloud density per meter to automotive systemswithout the high-speed trade-offs.

That means the L1 delivers more than enough spatial resolution for navigation, obstacle avoidance, and SLAM in indoor and low-speed environmentsmaking it a smart, efficient choice for mobile robotics.

Whole-House Dynamic Scanning

The Unitree L1 4D LiDAR rapidly captures accurate 3D structural data of entire indoor spaces . This enables precise positioning and autonomous navigation for mobile robots while unlocking advanced functions like whole-house cleaning, object sorting, and environmental mapping.

Non-Repetitive Static Scanning

Thanks to its 360 90 ultra-wide-angle field of view , L1 performs non-repetitive scanning with exceptional precision. It generates high-density point clouds that deliver image-level detailideal for SLAM, obstacle detection, and spatial reconstruction.

Close-Range Dynamic Detection

With a minimum detection distance of just 0.05m , L1 excels at near-field recognition. Its ultra-low blind zone makes it perfect for navigating tight spaces, detecting small objects, and performing fine-grained environmental analysis.
