HiMe: Hierarchical Embodied Memory for Long-Horizon Vision-Language-Action Control

arXiv:2607.03449v1 Announce Type: cross Abstract: Current Vision-Language-Action (VLA) models excel at robotic manipulation but often struggle with non-Markovian tasks requiring long-term memory and reasoning due to their reliance on immediate observations. Existing solutions face a ''frequency-competence paradox,'' where stronger reasoning models are too slow for real-time control, while faster models lack sufficient reasoning capabilities. To resolve this architectural misalignment, we propose HiMe, a Hierarchical Embodied Memory framework that decouples embodied intelligence into a high-fre

Why this matters
Why now

The increasing complexity of robotic tasks and the limitations of current Vision-Language-Action (VLA) models in handling non-Markovian, long-horizon problems are driving research into novel architectural solutions like Hierarchical Embodied Memory.

Why it’s important

Improving robotic intelligence in areas requiring long-term memory and reasoning is critical for expanding AI's capabilities beyond narrow, immediate tasks, enabling more autonomous and versatile physical agents.

What changes

This research proposes an architectural solution to the 'frequency-competence paradox' in VLA models, suggesting a path towards more effective and practical long-horizon autonomous control in robotics.
