An Event-Driven, Asynchronous, Behavioral State Machine Library for ROS2 (Robotic Operating System) applications written in C++

ROS 2 nodes wrapping core MRPT functionality: localization, autonomous navigation, rawlogs, etc. SLAM is in other packages.

A rclcpp-compatible true zero-copy IPC middleware that supports all ROS message types, including message structs already generated by rosidl.

An async first rust client for ROS supporting multiple backends: ROS1, ROS2, rosbridge, and Zenoh.

VLink is a high-performance C++ communication middleware for autonomous driving and embodied intelligence, positioned as a full-scenario alternative to ROS 2.

PX4 Autopilot Software

ROS2 LiDAR-inertial SLAM and multi-session alignment

ROS 2 localization for outdoor robots: IMU, wheel encoders and GPS fused in a 23-state UKF at 100 Hz. When the estimate goes wrong it reports which sensor and why, instead of drifting silently. Apache 2.0.

A Robust Approach for LiDAR-Inertial Odometry Without Sensor-Specific Modelling

Generic robotic controllers to accompany ros2_control

Modular AI HAL (Hardware Abstraction Layer) for Robots
