Requires a ROS 2 environment, a serial connection to the sensor, and a udev rule for USB access.
This project is a driver that lets a robot software framework called ROS 2 talk to a specific spinning laser sensor, the RPLIDAR C1, which robots use to measure distances around them and build a map of their surroundings. It was built specifically to work with a robot platform called LGDXRobot2, though the author notes it might work with other RPLIDAR models if the connection speed is adjusted, without any guarantee. The driver is written from scratch in C++20 using the Boost library, and it is built to automatically reconnect to the sensor if the connection drops, which matters for a robot that needs to keep sensing its surroundings reliably. It only works over a direct serial cable connection, not over a network, and its settings must be fixed before the software starts rather than changed while it is running. One of the sensor's scan modes is not fully supported and its results are described as not fully tested. Installing it involves either adding the maker's own software package repository on a Linux system and installing it directly, or building it from the source code using the standard ROS 2 build tool after cloning the repository. A separate step adds a system rule so the operating system recognizes the sensor's USB connection correctly. Once installed, a single command launches the driver, and it publishes the sensor's readings on a standard ROS 2 data channel that other robot software can subscribe to. Internally, the code is organized into a handful of classes: one that manages the overall node, one that handles the raw serial communication, one that reads the sensor's configuration, and two interchangeable classes that handle the two different scanning modes the sensor supports. The README does not state a software license for this project.
A ROS 2 driver written in C++ that connects the RPLIDAR C1 laser sensor to a robot, publishing its distance scans over serial.
Mainly C++. The stack also includes C++, ROS 2, Boost.Asio.
Setup difficulty is rated moderate, with roughly 30min to a first successful run.
Mainly developer.
