🤖 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 1 m/s.
🚗 By comparison, top-tier automotive-grade LiDAR systems generate up to 1.5 million points/sec, but when traveling at 200 km/h (55 m/s), the effective density drops to just 27,000 points/meter—even in safety-critical scenarios.
🐢 Mobile robots typically operate at much slower speeds, often under 1 m/s. When paired with the L1 LiDAR, they achieve a comparable point cloud density per meter to automotive systems—without 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 environments—making 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 detail—ideal for SLAM, obstacle detection, and spatial reconstruction.
🔍 Close-Range Dynamic Detection
With a minimum detection distance of just 0.05 m 📏, 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.
