RPLIDAR A1 is a low cost 360 degree 2D laser scanner (LIDAR) solution developed

by SLAMTEC. The system can perform 360degree scan within 12 meter range. The

produced 2D point cloud data can be used in mapping, localization and

object/environment modeling.

RPLIDAR A1’s scanning frequency reached 5.5 hz when sampling 360 points each

round. And it can be configured up to 10 hz maximum.

RPLIDAR A1 is basically a laser triangulation measurement system. It can work

excellent in all kinds of indoor environment and outdoor environment without

sunlight.

System connection

RPLIDAR A1 contains a range scanner system and a motor system. After power on

each sub-system, RPLIDAR A1 start rotating and scanning clockwise. User can get

range scan data through the communication interface (Serial port/USB).

Figure 1-1 RPLIDAR A1 System Composition

RPLIDAR A1 comes with a speed detection and adaptive system. The system will

adjust frequency of laser scanner automatically according to motor speed. And

host system can get RPLIDAR A1’s real speed through communication interface.
