PhysLadder: A Hierarchical Sim-Real Matching Benchmark for Contact-Rich Manipulation, Evaluating GPT-6 Astra

The authors propose PhysLadder, a hierarchical sim-real benchmark for evaluating physical interaction capabilities in contact-rich manipulation, comprising 16 household tasks divided into three cumulative levels: contact selection and geometric alignment (L1), force regulation under sustained contact (L2), and coordinated contact reconfiguration and force regulation (L3).
