Product Overview
Introduction
Unitree 4D LiDAR-L1 is a cost-effective, safe, and reliable 4D LiDAR (3D position + 1D grayscale) that
can achieve high-speed laser ranging sampling at 21,600 times per second. It can be widely used in
robotics, smart cities, smart toys, logistics, and other fields, supporting functions such as mapping,
positioning, recognition, obstacle avoidance, environment scanning, and 3D reconstruction.
The L1 radar can detect objects as close as 0.05 meters and as far as 30 meters away (90% reflec-
tivity).
The L1 unit is compact and lightweight, weighing only 230 grams, making it suitable for general
robot environment scanning, positioning, mapping, navigation, and obstacle avoidance.
The L1 has outstanding ultra-wide-angle scanning capabilities, with a field of view (FOV) expanding
to 360 ° horizontally and 90 ° vertically, enabling three-dimensional space detection of a hemispheri-
cal field of view. Its application range can be expanded to more commercial scenarios.
The L1 has an IMU module with built-in 3-axis acceleration and 3-axis gyroscope, supporting a push
frequency of 250Hz.
The L1's azimuthal scanning frequency is 11Hz, and its vertical scanning frequency is 180Hz, with an
effective sampling frequency of 21,600 points/second. The L1 not only has excellent performance
but also has high reliability, meeting the working environment temperature range of -10℃~60℃ and
IEC-60825 Class 1 eye safety level.
