🤖 AI Summary
Traditional robotic simulators struggle to simultaneously support large-scale parallel training and high-fidelity physical modeling, further hindered by the scarcity of high-quality training data. This work presents the first systematic analysis of NVIDIA Isaac Sim from both architectural and applied perspectives, elucidating its core mechanisms in GPU-accelerated simulation, high-fidelity physics, and synthetic data generation. Through comparative evaluation against mainstream simulation platforms, the study highlights Isaac Sim’s distinctive strengths and limitations in scalability, physical accuracy, and data-driven learning. The authors distill five representative robotic application paradigms, advocate for a simulation-centric training framework, and outline promising future directions, including open-world physical learning.
📝 Abstract
Simulation has become a core infrastructure for robotics research. Unlike previous simulators, NVIDIA Isaac Sim leverages GPU acceleration to enable large-scale parallel training and physics-accurate modeling. Its synthetic data generation pipeline alleviates the scarcity of high-quality training data, supporting data-driven robot learning and large-scale simulation-centric experimentation. However, existing surveys often treat it as one simulator among many, without a systematic analysis of its architectural characteristics, usage patterns, and limitations. This survey reviews Isaac Sim from system and application perspectives, outlining its architecture and comparing it with widely used simulators. We analyze representative studies across five major domains and summarize common usage patterns, particularly in data generation and high-fidelity simulation. We also outline key future directions and challenges, including physics open-world learning, simulation-centric training and practical usability constraints.
