Product Description

The SLAMTEC RPLIDAR A2M12 is a revolutionary low-cost 360-degree 2D laser scanner (LIDAR) developed by SLAMTEC. It uses high-speed rotating core and laser triangulation ranging principles to generate high-precision point cloud data in real-time, helping users quickly build environment maps and achieve accurate positioning. The product features a modular design, with the core component separated from the mechanical drive, ensuring long-term stable operation.
The system consists of a ranging core and a rotating mechanism. The start, stop, and speed of the motor are controlled via PWM signals, and output data includes distance, angle, and scan flags. Each sample point data is checksum-verified to ensure integrity. Scanning data is defined in a left-handed coordinate system, with the front as the X-axis and angles increasing clockwise, making it easy to integrate into various navigation systems.
