Safe Multi-Robot Coordination via VLM-LLM Reasoning and Reachability Analysis
Mohamed Dwedar, Ahmad Hafez, Alexander Jesser +1
Safe coordination in heterogeneous machine-to-machine (M2M) robotic systems is challenging when robots differ in sensing capabilities, environmental awareness, and motion execution…
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…
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…
Safe LLM-Controlled Robots with Formal Guarantees via Reachability Analysis
Ahmad Hafez, Alireza Naderi Akhormeh, Amr Hegazy +1
The deployment of Large Language Models (LLMs) in robotic systems presents unique safety challenges, particularly in unpredictable environments. Although LLMs, leveraging zero-shot…
