Physical-WAM, a physical-world action model for embodied AI, and the RoboTwin-Phys physical drift benchmark were made public by Memo Space (美梦空间) on September 26, 2026 at the fifth Global Digital Trade Expo. The company says Physical-WAM uses physical tokens to support physical perception, future-state prediction and action correction. RoboTwin-Phys adds 13 categories of physical perturbations and releases its code, dataset and leaderboard as open source. Shanghai Suochen Information Technology Co., Ltd.
