The RPLIDAR A2 is the next generation of 360 degree 2D LIDARs. Each RPLIDAR A2 can take up to 8000 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 12 meters (18m with a bit of firmware adjustment). Additionally, the generated 2D point cloud data can be used in mapping, localization and object/environment modeling!
