RPLidar A1M8 360 Degree Laser Scanner Kit - 12M Range

RPLIDAR refers to a line of low-cost, 360-degree 2D laser scanners (LIDAR) developed by SLAMTEC, designed for applications like robot navigation, mapping, and object detection.

These sensors use either a laser triangulation or a time-of-flight (ToF) system to scan their surroundings, creating a 2D point cloud map of the environment. They are frequently used in robotics for tasks like localization and obstacle avoidance.

Key features and characteristics

360-degree scanning: The sensors continuously rotate to scan the environment in all directions.
2D mapping: They generate 2D point cloud data that can be used to build an outline map of the surroundings.
Applications: Common uses include robot navigation, localization (determining a robot's position), and object/environment modeling.
Technology: They use either laser triangulation or time-of-flight (ToF) ranging principles to measure distances.
Performance:
- Sample rate: A high sample rate allows for more detailed and accurate mapping. For example, the RPLIDAR A1 can sample up to 8000 times per second.
- Scanning frequency: This is the number of full scans completed per second. It is often configurable to suit different needs.
Safety: Some models are designed to be safe for use around humans and pets and comply with FDA Class 1 laser standards.
Durability: Newer models often incorporate technologies like contactless power and signal transmission to ensure long-term stability and reliability.
Environment: They generally work well in indoor environments and outdoor environments that do not have direct sunlight.
