CompCPZ: Preserving Multi-Modal Intent in Language-Guided Robot Manipulation
Zhen Zhang, Ahmad Hafez, Peng Xie +3
A robot asked to "place the cup near the red plate or the blue plate" may reach the centroid between them and appear geometrically successful, while satisfying neither disjunct of…

Probabilistic Reachable-Action Verification of Visuomotor Policies via Set-Based Training
Yanliang Huang, Zhuocheng Zhang, Peng Xie +5
Reachability analysis for visuomotor policies is difficult because large visual encoders make end-to-end set propagation computationally expensive and excessively conservative. We…

Certifying Plans under Model Mismatch: A Trilemma for Reachability from Scarce Data
Yanliang Huang, Zhen Zhang, Ahmad Hafez +4
Sim-to-real policies are designed under nominal dynamics, but target-system trials may yield only a few isolated one-step transitions. We study pre-execution certification of a fix…
