Zhao Chenhui (CTO of RoboX) gave a keynote at the AI Standardization Forum, while Professor Joseph Sifakis (Turing laureate, Chief Scientific Advisor) joined via video to share insights on trustworthy Robotaxis. Sifakis, a renowned authority on trustworthy autonomous systems, said Robotaxi development depends on AI models and the system's ability to operate safely in open, complex, uncertain environments. Trustworthy systems require built-in safety from the start, coordination among vehicles, cloud, dispatch, and networks, plus real-time monitoring. Drawing on this theory, CaoCao proposed a capability framework with three pillars: Trustworthy Vehicles, Runtime Assurance, and Operations Systems, for scalable commercial solutions. Zhao detailed practices: For Vehicles, CaoCao launched China's first purpose-built Robotaxi with redundant vehicle-level architecture meeting international safety standards.
