RP LIDAR A2

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. And equipped with SLAMTEC patented OPTMAG technology, it breakouts the life limitation of traditional LIDAR system so as to work stably for a long time. The system can perform 2D 360-degree scan within a 8-meter range. The generated 2D point cloud data can be used in mapping, localization and object/environment modeling. It has excellent performance in all kinds of indoor environments and outdoor environments without direct sunlight exposure.

The typical scanning frequency of the RPLIDAR A2 360° Laser Scanner 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. The RPLIDAR A2 consists of a range scanner core and mechanical powering parts which makes the core rotate at a high speed. When it functions normally, the scanner will rotate and scan clockwise. Users can get the range scan data via the communication interface of the RPLIDAR and control start, stop and rotating speed of the rotatation motor via PWM.

The RPLIDAR A2 comes with a rotation speed detection and adaptive system. The system will adjust the angular resolution automatically according to the actual rotating speed.
