RobotArena $\infty$: Scalable Robot Benchmarking via Real-to-Sim Translation

arXiv:2510.23571v3 Announce Type: replace-cross Abstract: The pursuit of robot generalists, agents capable of performing diverse tasks across diverse environments, demands rigorous and scalable evaluation. Yet real-world testing of robot policies remains fundamentally constrained: it is labor-intensive, slow, unsafe at scale, and difficult to reproduce. As policies expand in scope and complexity, these barriers only intensify, since defining "success" in robotics often hinges on nuanced human ju
