What is the difference between scan frequency and sample rate?
The sample rate is how many ranging points are collected per second, while the scan frequency is how many full 360 degree rotations are completed each second.
Is this suitable for outdoor use?
This model is generally better suited to indoor or controlled-light robotics work. Strong ambient light and reflective environments can affect performance compared with dedicated outdoor LiDAR systems.
Can it be used with ROS?
Yes. The RPLIDAR A1 has SDK, ROS, and ROS 2 support, making it practical for robotics software development and SLAM experiments.
