More info

The RPLIDAR A2 is the next generation low cost 360 degree 2D laser scanner (LIDAR) solution developed by SLAMTEC. It can take up to 4000 samples of laser ranging per second with high rotation speed.

The system can perform 2D 360 - degree scan within a 6 - meter range. The generated 2D point cloud data can be used in mapping, localization and object/environment modeling. The typical scanning frequency of the RPLIDAR A2 is 10hz (600rpm). Under this condition, the resolution will be 0.9 °. And the actual scanning frequency can be freely adjusted within the 5 - 15hz range according to the requirements of users.

It adopts the low cost laser triangulation measurement system developed by SLAMTEC , which makes the RPLIDAR A2 has excellent performance in all kinds of indoor environment and outdoor environment without direct sunligh t exposure.

Device supported by ROS.

Main features:

  • Low Cost 360 Degree Laser Range Scanner
  • 4000 samples/s 10Hz
  • Range: 6m
  • Rotation speed: 600 RPM
  • Resolution: 0.9°

System connection

The RPLIDAR A2 consists of a range scanner core and the mechanical powering part which makes the core rotate at a high speed. When it functions normally, the scanner will rotate and scan clockwise. And users can get the range scan data via the communication interface of the RPLIDAR and control the start, stop and rotating speed of the rotate motor via PWM.110090081_1.jpg

The sensor comes with a rotation speed detection and adaptive system. The system will adjust the angular resolution automatically according to the actual rotating speed. And there is no need to provide complicated power system for laser. In this way, the simple power supply schema saves the bill of materials cost. If the actual speed of the RPLIDAR is required, the host system can get the related data via communication interface.


The RPLIDAR A2 is based on laser triangulation ranging principle and adopts the high-speed vision acquisition and processing hardware developed by SLAMTEC. The system ranges more than 4000 times per second.
