arXiv:2605.22183v3 Announce Type: replace-cross Abstract: Vision-Language-Action (VLA) models have emerged as a promising paradigm for generalist robotic manipulation. A common design in current architectures maps language instructions and visual observations to actions in a single forward pass. While conceptually simple, this formulation entangles instruction comprehension, spatial scene understanding, and motor control within a single learning objective. As a result, the action expert must implicitly relearn cognitive and perceptual capabilities already present in the pretrained VLM, which c
The rapid advancement in general-purpose Vision-Language Models (VLMs) is enabling their application to robotic control, leading to a need for more efficient architectural designs to leverage their capabilities fully.
This research suggests a more effective modular approach to VLA models, potentially accelerating the development of more capable and generalist robotic manipulation systems by avoiding redundant learning.
Current VLA models often struggle with entangling various learning objectives; this proposal for 'Action with Visual Primitives' offers an alternative architecture that could streamline development and deployment.
