A Critical Review of Visiomotor Policies and VLA Models in Robotic Manipulation

This post summarizes a recent review I authored, titled “Visiomotor Policies, Vision-Language-Action Models, World Models for Robotic Manipulation: A Review”. The paper provides a comprehensive analysis of the methodological landscape in robotic learning, specifically contrasting specialized task-specific policies with general-purpose Vision-Language-Action (VLA) models. Overview The current paradigm of robotic learning is fragmented. On one side, specialized policies offer high robustness and precision in controlled environments but struggle with novel instructions or unseen visual scenes.
