LIDAR RPLIDAR - 360 Degree Laser Scanner Development Kit (Seeed)

The RPLIDAR A1M1 is a cost-effective 360-degree 2D laser scanner developed by RoboPeak, designed for mapping, localization, and environment modeling. With a scanning range of up to 6 meters, it provides high-resolution 2D point cloud data across a 360-degree field. It operates at a default scanning frequency of 5.5 Hz, sampling 360 points per rotation, and can be configured to reach 10 Hz. Built on laser triangulation technology, the RPLIDAR performs well in indoor and shaded outdoor environments.

It comprises a range scanner and a motor system, which starts rotating upon powering up, allowing clockwise scanning. The data is accessible via UART or USB interfaces. A standout feature is its adaptive system that adjusts scanning frequency based on motor speed. The laser scanner emits modulated infrared signals, which are processed by an embedded DSP to calculate distance and angle values. With over 2000 measurements per second, it’s ideal for real-time environmental analysis.

Package Includes

  • 1 x RPLIDAR A1 (with embedded PWM motor driver)
