This digital TestBed is an advanced simulation environment built on NVIDIA Isaac Sim (Omniverse), specifically tailored for the development and benchmarking of autonomous mobile robots (AMRs). It provides a high-fidelity “Digital Twin” infrastructure where users can test navigation stacks (such as ROS 2 Nav2) in photorealistic environments with accurate physics. The platform enables complex scenario testing, including multi-robot simulation infrastructure for coordination research, dynamic obstacle avoidance, and sensor fusion (LiDAR, Depth Cameras, IMU) without the risk of hardware damage. Its key differentiator is the high-fidelity sensor simulation and the ability to easily bridge the “Sim-to-Real” gap. It serves as a primary tool for researchers and students to validate algorithms in varied industrial and office-like 3D scenes before physical deployment.
