Summary

PDDL-ART generated symbolic domains and problems from one expert demonstration, then corrected them through syntax, semantics and execution.

Across engine-maintenance and household tasks, the VLM-based system reported 93.3 percent average success versus 78.3 percent for its planner baseline. Tool-grounded predicate checks helped with relations not visible in a single frame; performance still depends on the demonstration and available high-level actions.

Why it matters
