The RPLIDAR A3M1 is the next generation of 360 degree 2D LIDARs. Each RPLIDAR A3 can take up to 16000 samples of laser ranging per second thanks to its high rotation speed. The on-board system can perform 2D 360° scans within a range of 25 meters in enhanced mode and 20 meters in outdoor mode. Additionally, the generated 2D point cloud data can be used in mapping, localization, and object/environment modeling!
The RPLIDAR A3M1 consists of a long 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 allowing you to be able to get the range scan data via the communication interface of the RPLIDAR and control the start, stop and rotating speed of the rotation motor via PWM. The typical scanning frequency of the RPLIDAR A3 360° Laser Scanner is 10hz (600rpm) with a scanning frequency that can be freely adjusted within the 5-20Hz range according to the requirements of what you need.
What makes the A3M1 special is its ability to switch between two different modes of operation (mentioned earlier): enhanced mode and outdoor mode. In enhanced mode, the RPLIDAR works within the maximum ranging radius and sampling rate to for optimum mapping performance in indoor environments. While in the outdoor mode, the RPLIDAR A3M1 works with a more reliable resistance to daylight interference, which prevents it from being “blinded” in outdoor environments.
Thanks to the improvements in SLAMTEC hardware operating performance and related algorithm, RPLIDAR A3M1 works well in all kinds of indoor environment and outdoor environment with direct sunlight. Also, before leaving the factory, every RPLIDAR A3 has passed strict testing to ensure the laser output power meet the eye safety standards of IEC-60825 Class I.
