Unitree 4D LiDAR L1

360° × 90° hemispherical scan with 4D output (3D position + grayscale intensity)

0.05 m near-blind zone for precise close-range detection

Max range: 20 m (L1 PM) / 30 m (L1 RM); reliable on low-reflectivity targets

Effective 21,600 pts/s (43,200 samples/s) for dense mapping

Built-in 6-axis IMU (gyro + accel), 250 Hz output for stable SLAM

±2 cm accuracy with 8 mm resolution

Eye-safe 905 nm Class 1; works in bright light and −10 to 60 °C

12 V, TTL UART @ 2 Mbps; great for mobile robots, SLAM, navigation & obstacle avoidance
