The RPLIDAR A1M1 is a cost-effective 360-degree 2D laser scanner developed by RoboPeak, designed for applications in mapping, localization, and environment modeling. With a scanning range of up to 6 meters, it captures a comprehensive 360-degree view of its surroundings by producing high-resolution 2D point cloud data. The system operates with a scanning frequency of 5.5 Hz, sampling 360 points per rotation, and can be configured to reach up to 10 Hz for faster scanning. Built on laser triangulation measurement technology, RPLIDAR is versatile and performs well in both indoor and outdoor environments, as long as it is shielded from direct sunlight. It is composed of a range scanner system and a motor system, which initiates rotation upon powering up, allowing for clockwise scanning. The data collected can be accessed via a communication interface such as UART or USB, ensuring seamless integration with host systems. A standout feature of RPLIDAR is its speed detection and adaptive system, which automatically adjusts the scanning frequency based on motor speed. The motor operates with a power supply range of 3.6V to 6V, while the digital system runs on 3.6V to 5V, further simplifying its setup. Additionally, the laser scanner emits modulated infrared signals that reflect off objects in the environment, allowing the embedded DSP system to process and output precise distance and angle values. With a built-in angular encoding system, RPLIDAR performs high-speed, high-accuracy scanning at over 2,000 measurements per second, making it ideal for projects that require precise real-time environmental data.
