arXiv:2606.25800v1 Announce Type: new Abstract: Effective online adaptation of vision-language-action (VLA) models remains challenging, as sparse rewards provide weak supervision for high-dimensional autoregressive action policies. Although self-distillation can in principle provide denser training signals, we find that text-based privileged teachers conditioned on demonstrations, retrieved experiences, or high-level plans are ineffective for VLA adaptation, exposing a modality gap between symbolic guidance and low-level robot actions. We propose ROAD-VLA, an advantage-guided self-distillation
The continuous development in vision-language models for robotics necessitates more robust online adaptation methods to overcome challenges with sparse rewards and modality gaps.
This development addresses a critical bottleneck in the practical deployment of autonomous robotic systems, enabling more reliable and adaptive AI in real-world, unstructured environments.
The ability of VLA models to self-adapt and learn from experience online improves, reducing the need for extensive pre-training or human intervention in dynamic scenarios.
