Towards Building AI-CPS with NVIDIA Isaac Sim: An Industrial Benchmark and Case Study for Robotics Manipulation

As a representative cyber-physical system (CPS), robotic manipula-tors have been widely adopted in various academic research and industrial processes, indicating their potential to act as a universal interface between the cyber and the physical worlds. Recent studies in robotics manipulation have started employing artificial intelli-gence (AI) approaches as controllers to achieve better adaptability and performance. However, the inherent challenge of explaining AI components introduces uncertainty and unreliability to these AI-enabled robotics systems, necessitating a reliable development platform for system design and performance assessment. As a foun-dational step towards building reliable AI-enabled robotics systems, in this paper, we propose a public benchmark for robotics manipu-lation. It leverages NVIDIA Omniverse Isaac Sim as the simulation platform, encompassing eight representative manipulation tasks and multiple AI software controllers. An extensive empirical evalu-ation is conducted to analyze the performance of AI controllers in solving robotics manipulation tasks, enabling a relatively thorough understanding of their effectiveness. To further demonstrate the applicability of our benchmark, we also developed the first falsification framework that is compatible with Isaac Sim. This framework bridges the gap between traditional falsification methods and mod-ern physics engine-based simulations. The effectiveness of different optimization methods in falsifying AI-enabled robotics manipu-lation with physical simulators is also examined. Our work not only establishes a foundation for the design and development of AI-enabled robotics systems but also provides practical experience and guidance to practitioners in this field, promoting further research in this critical academic and industrial domain.
