ROS Robot Operating System

ROS2 is the second-generation Robot Operating System, redesigned from ground up for production robotics, real-time guarantees, and security. It uses DDS (Data Distribution Service) for deterministic, distributed pub/sub communication, enabling complex robotic systems with guaranteed latency bounds. Production ROS2 systems combine real-time Linux kernels (PREEMPT_RT), DDS security plugins, health monitoring, and careful tuning for safety-critical applications in autonomous vehicles, industrial robots, and service robots. ROS2 is becoming the standard for production robotics. Companies deploying autonomous systems (Tesla, Waymo level, ABB industrial robots) need ROS2 expertise for real-time system design, safety, and scaling. Advanced ROS2 skills—real-time tuning, DDS configuration, security—are rare and command 20–35% premiums over general robotics engineers. Critical for roles in robot architects, infrastructure engineers, and senior robotics roles.
