Dynamic whole-home scanning indoors
L2 can quickly and accurately obtain 3D structural information about a home. This information supports mobile robots’ localization and autonomous navigation; it can also help expand robots’ functions, such as home cleaning and tidying.
Dynamic real-world scanning outdoors
L2 is designed to withstand the effects of ambient indoor light and strong outdoor light. The manufacturer states that stable range measurement and high-precision mapping are possible outdoors under strong light of 100 klux.
The 100 klux claim for Unitree 4D LiDAR L2 is a condition specified on the manufacturer’s page.
Non-repetitive scanning
L2 produces high-precision, dense point-cloud data using omnidirectional ultra-wide-angle non-repetitive scanning; the manufacturer describes the result as a photo-level scanning effect.

Parameter comparison
Unitree 4D LiDAR L2 is a LiDAR sensor designed for depth sensing and environmental mapping. Its wide field of view and high-resolution 4D scanning capabilities provide a strong foundation for object detection and tracking in dynamic environments. L2 is developed to acquire precise distance, speed, and direction information for moving and stationary objects. Its modular design makes it easy to integrate into different systems, and its real-time data stream makes it suitable for use on autonomous platforms.

According to the manufacturer’s footnotes, typical reflectivity measurements depend on environmental and target characteristics; detecting objects with different reflectivities within range may slightly reduce point cloud accuracy at some positions. The maximum range is directly above L2. Negative-angle mode expands the field of view from 360° × 90° to 360° × 96°; the maximum measurement distance may be slightly shorter for the additional 6°. In automatic heating mode between -10°C and 30°C, no point cloud is generated until the required temperature is reached; peak power may reach 13 W. Stable and peak power vary according to environmental conditions. Parameters may vary depending on the operating scenario and LiDAR configuration.
Safety and measurement conditions
The manufacturer describes the product as intended for civilian robotics use, advises against hazardous modifications and use, and requires compliance with local regulations. Technical values may vary across operating scenarios and LiDAR configurations; validation is required for application conditions.
The manufacturer’s safety and legal warnings are not a warranty or promise of use provided by Robotik Çözümler.
