PhysMem introduces a three-tier memory system (episodic, working, long-term) that enables VLMs to learn physical principles from interaction. This structured approach avoids the limitations of raw experience retrieval by abstracting verified knowledge into reusable principles.
The system continuously refines memory, transforming raw experiences into testable hypotheses and promoting validated knowledge.
Inspired by the scientific method, PhysMem operates through a four-phase loop: experience collection, hypothesis generation, action-level attribution, and principle promotion. This ensures that only verified knowledge guides future decisions, preventing rigid reliance on outdated experiences.
Resonance checking prioritizes learning on novel situations, focusing resources where new understanding is most needed.
Experiments across various VLMs and difficulty levels show that PhysMem provides significant performance gains, especially for complex tasks. It amplifies existing VLM capabilities, allowing models to adapt to novel physical properties encountered at test time.
The system's ability to abstract principles allows it to stabilize performance even with a moderate number of principles, demonstrating efficient knowledge acquisition.

Real-world Application: Ball Navigation
Scenario: A robot is tasked with pushing a soccer ball through an obstacle course. Initial attempts fail due to misjudgment of ball dynamics and surface friction, which are not visually apparent.
Solution: PhysMem enables the VLM planner to learn specific contact dynamics through trial and error. It generates hypotheses about optimal push speeds and angles, verifies them through interaction, and promotes verified principles like 'use low speed after passing the archway'.
Outcome: Performance improves significantly, with the robot consistently reaching the target region after accumulating principles, demonstrating adaptive physical understanding.
