Product Introduction

Product Features

➢ High accuracy, stable performance ​➢ High resolution of ranging angle, up to 0.6 degrees ​➢ Good obstacle avoidance effect, the smallest object with a diameter of 3mm can be ​detected ​➢ Wide detection range, no blind zone in combination, FOV up to 100 degrees ​➢ Small detection range blind area, detectable distance is 25mm~300mm ​➢ Class I eye safety ​➢ 10000h Service life



➢ GS2 lidar*1(Standard version of the GS2 lidar. )

➢ USB Type-C Cable*1(Use with USB adapter board to connect GS2 and PC. USB cable is both a power supply cable and a data cable)

➢ USB Adapter Board*1(Realize the function of USB to UART, which is convenient for the fastinterconnection between GS2 and PC.)


Note: USB Adapter board has two USB TYPE C interface: USB_DATA, USB_PWR. ​USB_DATA: Data powered interface. In most cases, this interface can be used to meet power and ​communication requirements. ​USB_PWR: Auxiliary power supply interface. The USB interface of some development platforms has weak ​current drive capability. At this time, auxiliary power supply can be used.

Ultra wide FOV to assist robot vacuum cleaner through blind spots

Field of View up to 100 degrees, Wide range of detection

YDLIDAR provides 808nm and 850nm two waveband options, and the detection signals do not interfere with

each other. Two FOVs for better scanning results.


Obstacle avoidance along the wall with performance improvement

The GS2 can obtain more measurement information in the vertical direction, helping smart devices such as robot vacuum cleaner and service robots with accurate real-time monitoring of the edge, efficiently complete multiple difficult tasks.

Compact and light, flexible installation

The size of the whole device is only 25.6 (L) × 23.6 (H) × 10.8 (W) mm, which can be flexibly and easily integrated into various small smart devices. It can fully meet the refined detection needs of intelligent equipment such as robot vacuum cleaner.

Multiple authoritative certifications, high safety performance


➢ Robot obstacle avoidance ​➢ Obstacle avoidance of smart equipment ​➢ Navigation and obstacle avoidance of home service robots/vacuum clean robots

Installation and Dimensions

Note: GS2 has two forms of use, GS2-T stands for top entry type, GS2-S stands for side entry type, and the default factory is side entry type.

Performance Parameter


Note 1: It is factory FQC standard value, 80% reflectivity material object.

Note 2: The relative error value indicates the accuracy of the Lidar measurement. Relative error (mean value) =(average measured distance-actual distance)/actual distance *100%, sample size: 100pcs.

Note 3: Lidar is a precision device, please avoid using Lidar under high or low temperature or strong vibration situation, the relative error parameter index will be relatively larger, and it may exceed the typical value.
