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

by SLAMTEC. The system can perform 360 degree 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 5.5hz when sampling 1450 points each

round. And it can be configured up to 10hz

maximum.

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

excellent in all kinds of indoor environment and outdoor environment without

direct sunlight exposure.

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).

If you increase the scanning frequency to 5.5hz ~ 10Hz, you need to supply 9V to the motor separately.
