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.

The simple power supply saves LIDAR system’s BOM cost and makes RPLIDAR A1

much easier to use. Detailed specification about power and communication

interface can be found in the following sections.

Mechanism

RPLIDAR is based on laser triangulation ranging principle and uses high-speed

vision acquisition and processing hardware developed by SLAMTEC. The system

measures distance data in more than 8000 times’ per second and with high

resolution distance output (<1% of the distance).

RPLIDAR emits modulated infrared laser signal and the laser signal is then

reflected by the object to be detected. The returning signal is sampled by vision

acquisition system in RPLIDAR A1 and the DSP embedded in RPLIDAR A1 start

processing the sample data and output distance value and angle value between

object and RPLIDAR A1 through communication interface.
