RoboCasa-Shift evaluates vision-language-action policy robustness in long-horizon household tasks in simulation. The authors compare clean and shifted versions of the same episodes, tracking official task success and ordered simulator-state milestones. Camera orientation L1 produced zero aggregate success-rate degradation, although eight of 80 matched pairs changed outcome. Tests covered one policy and four clean-qualified tasks, without real-world validation.
