RoboCasa-Shift: Stage-Aware Robustness Evaluation of Vision-Language-Action Policies in Long-Horizon Household Manipulation

Vision-language-action (VLA) robustness is commonly summarized by aggregate task success, which obscures how individual executions change under distribution shifts and where failures emerge in long-horizon tasks. We introduce \textbf{RoboCasa-Shift}, a diagnostic robustness benchmark built on RoboCasa365 that combines...

Accurate Modeling and Stability Enhancement Methods for Grid-Following and Grid-Forming Hybrid-Controlled Converters

With the widespread application of renewable energy grid-connected technologies in power system, grid-connected converters are increasingly challenged by more complex operating conditions. A particularly notable issue is that the short circuit ratio (SCR) of grid significantly affects the stability of grid-connected co...
