Bringing open-source RTOS technology into space, our team is currently developing a space-robotics system powered by Zephyr RTOS. While product details remain confidential at the time of CFP submission, we plan to disclose concrete information by the event, including mission objectives and system architecture. The project is under active coordination for rocket launch with JAXA and NASA, and the talk will highlight how Zephyr’s lightweight, modular, and reliable architecture makes it an ideal choice for real-world space missions. Attendees will gain insights into applying Zephyr to mission-ready embedded systems.
