Grasp Execution Without a Planner: Configuration-Space Grasp Distance Fields with Certified Safety & Guaranteed Quality
Clinton Enwerem, John S. Baras, Calin Belta
Mainstream plan-then-track approaches to multifingered grasp execution entail selecting a grasp, planning a collision-free trajectory, and tracking the resulting trajectory via a f…
FIRMGrasp: A Friction-Informed Risk Margin for Robust Grasp Synthesis
Clinton Enwerem, John S. Baras, Calin Belta
Classical grasp quality metrics assume one deterministic friction coefficient and therefore cannot assess whether a grasp maintains force closure across plausible friction values.…
EquiDexFlow: Contact-Grounded SE(3)-Equivariant Dexterous Grasp Generative Flows
Clinton Enwerem, John S. Baras, Calin Belta
Most learned dexterous grasp generators relegate contact forces to a downstream verification step, so a kinematically-plausible pose can still violate the conditions for a stable p…
IDDMBSE: Integrating Data-Driven and Model-Based Systems Engineering for Trusted Autonomous Cyber-Physical Systems
John S. Baras, Sai Sandeep Damera, Ryan Matheu +2
Autonomous cyber-physical systems (CPS) sit at the intersection of Model-Based Systems Engineering (MBSE) and data-driven Machine Learning and Artificial Intelligence (ML/AI), yet…
Variational Neural Belief Parameterizations for Robust Dexterous Grasping under Multimodal Uncertainty
Clinton Enwerem, Shreya Kalyanaraman, John S. Baras +1
Contact variability, sensing uncertainty, and external disturbances make grasp execution stochastic. Expected-quality objectives ignore tail outcomes and often select grasps that f…
Ternary Logic Encodings of Temporal Behavior Trees with Application to Control Synthesis
Ryan Matheu, John S. Baras, Calin Belta
Behavior Trees (BTs) provide designers an intuitive graphical interface to construct long-horizon plans for autonomous systems. To ensure their correctness and safety, rigorous for…
