One Word, Different Action: A Real-Robot Benchmark for Language-Conditioned Embodied Reasoning
Yiwei Liu, Luwei Yang, Shunbo Lei
Natural-language instruction changes can directly alter robot behavior. A reliable embodied system should preserve its action when the task is unchanged and update it correctly whe…
Active Perception for Embodied Disambiguation
Yiwei Liu, Luwei Yang
Natural language provides robots with a flexible task interface, but target ambiguity in embodied environments arises not only from user intent; it can also result from missing tas…
OCO-S: Online Convex Optimization with Stateful Costs and Sparse Communication
Yiwei Liu, Luwei Yang, Shunbo Lei
We study \textsc{OCO-S}, an online convex optimization setting in which decisions drive a stable dynamical state, losses are incurred along the induced state trajectory, and fi…
Delay-Robust Secondary Frequency Control via Passive Interconnection and Randomized Block Updates
Yiwei Liu, Luwei Yang, Shunbo Lei
This paper studies secondary frequency control in transmission networks subject to communication delays at the cyber-physical interface and limited per-update computation at the co…
