RPLIDAR A2 LIDAR is a 360-degree two-dimensional laser range scanner (LIDAR). The core of RPLIDAR A2 runs clockwise to perform a 360 degree omnidirectional laser range scanning for its surrounding environment and then generate an outline map for the environment. With the custom special parts and the carefully designed internal mechanical system, the RPLIDAR A2 keeps its excellent performance while cutting the thickness to only 4cm. It is ideal for all kinds of service robots.

Compared with the traditional belt drive mode, RPLIDAR A2 uses the self-designed brushless motor to reduce the mechanical friction in running. Therefore, the RPLIDAR A2 can run smoothly without any noise. The A2 is an inexpensive solution for projects that require obstacle detection, obstacle avoidance, and/or simultaneous localization and mapping (SLAM). All RPLIDAR products are ROS ready. The ROS package source can be found below.
