The RPLIDAR A3M1 is the next generation low cost 360 degrees 2D laser scanner (LIDAR) solution developed by SLAMTEC. It can take up to 16000 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 25-meter range. The generated 2D point cloud data can be used in mapping, localization and object/environment modeling. Compared with RPLIDARs in other series, RPLIDAR A3M1 has a more stable performance when detecting objects in the long distance, objects in white or black alternatively and objects under direct sunlight, which is ideal for map building in the outdoor environment within a 25-meter ranging radius. Therefore, it can be widely applied in many consumer-oriented business scenarios.
RPLIDRA A3M1 supports to work under two modes alternatively: enhanced mode and outdoor mode. In the enhanced mode, it works with the maximum ranging radius and sampling rate to realize an optimistic mapping performance in the indoor environments. While in the outdoor mode, RPLIDAR A3M1 works with a more reliable resistance to daylight interference, which prevents it from ?blind? in an outdoor environment. The typical scanning frequency of RPLIDAR A3M1 is 10Hz(600rpm), and the frequency can be freely adjusted within the 5-20Hz range according to the specific?requirements. With the 10Hz scanning frequency, the sampling rate is 16kHz and
the angular resolution is 0.225?.
Due 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. Meanwhile, before leaving the factory, every RPLIDAR A3M1 has passed the strict testing to ensure the laser output power meet the eye-safety standard of IEC-60825 Class 1.
The RPLIDAR A3M1 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.
The RPLIDAR A3M1 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 a complicated power system for RPLIDAR. In this way, the simple power supply schema saves the BOM cost. If the actual speed of the RPLIDAR is required, the host system can get the related data via the communication interface.
The RPLIDAR A3M1 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 16000 times per second.
