RPLiDAR A3M1 360 Degree Laser Scanner Kit – 25M Range Seeed

DESCRIPTION

RETIRED PRODUCT – We’ve stopped stocking this product or it has been retired by the manufacturer and is no longer for sale. This page remains available for its resources and as a source of potential interest.

The RPLIDAR A3M1 is the next generation low cost 360-degree 2D laser scanner (LIDAR) solution developed by SLAMTEC. It can take up to 16000 laser ranging samples per second at a high rotational speed. Equipped with SLAMTEC patented OPTMAG technology, it breaks free from the limitations of traditional LIDAR system so and can operate with stability for its lifespan. 

The system can perform 2D 360-degree scan within a 25-meter range. The generated 2D point cloud data can be used in mapping, localisation and object/environment modelling.

Compared with RPLIDARs in other series, RPLIDAR A3M1 has a more stable performance when detecting objects at a 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 scenarios. RPLIDRA A3M1 can operate in two different modes: enhanced mode and outdoor mode.

In the enhanced mode, it works with the maximum ranging radius and sampling rate to optimise mapping performance in the 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 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 algorithms the RPLIDAR A3M1 works well in all kinds of indoor environment and outdoor environments even with direct sunlight. 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.
