Legacy ROS2 drivers for Ouster OS-0, OS-1, and OS-2 lidars, providing sensor data processing and lifecycle management.
ROS2 Ouster Drivers is a legacy open-source ROS2 driver package for interfacing with Ouster OS-0, OS-1, and OS-2 lidar sensors. It provides tools to capture, process, and publish lidar data—including 3D point clouds, 2D scans, IMU readings, and sensor images—within the ROS2 ecosystem. The project solves the problem of integrating Ouster lidars into robotic applications that require deterministic data handling and custom processing pipelines.
Robotics engineers and researchers who are deploying Ouster lidars in existing ROS2-based applications, particularly those needing legacy firmware support or highly customizable data processing.
Developers choose this driver for its extensible architecture, support for lifecycle and component nodes, and fine-grained control over data processing. It offers a deterministic, self-contained alternative for applications that cannot immediately migrate to Ouster's newer official driver.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Allows custom processors for lidar data, enabling features like downsampling or alternative point cloud formats, as detailed in the Extensions section for tailoring output.
Uses ROS2 lifecycle nodes for deterministic setup/teardown and component nodes for efficient in-process data sharing, enhancing reliability in robotic systems.
Supports four timestamp modes including PTP and internal clock, crucial for precise synchronization in multi-sensor applications, with clear documentation on trade-offs.
Compatible with Ouster OS-x sensors running firmware 2.2-2.4, providing a solution for existing deployments that haven't upgraded to newer versions.
Explicitly marked as legacy with Ouster recommending their new driver, indicating potential bugs, lack of updates, and reduced community support over time.
Requires manual steps for IPv4 static addressing or IPv6 link-local configuration, which can be error-prone and time-consuming compared to automated solutions.
Heavily relies on advanced ROS2 features like lifecycle and component nodes, demanding significant expertise for deployment, customization, and troubleshooting.
