arXiv:2603.28730v2 Announce Type: replace-cross Abstract: Vision-language models (VLMs) have shown impressive capabilities across diverse tasks, motivating efforts to leverage these models to supervise robot learning. However, when used as evaluators in reinforcement learning (RL), today's strongest models often fail under partial observability and distribution shift, enabling policies to exploit perceptual errors rather than solve the task. We introduce SOLE-R1 (Self-Observing LEarner), a video-language reasoning model explicitly designed to serve as the sole reward signal for online RL. Give
The proliferation of advanced vision-language models (VLMs) is driving efforts to integrate them directly into robot training loops, seeking more robust and task-oriented learning. This specific research addresses the current limitations of VLMs as reward signals for reinforcement learning, making it a timely advancement.
This development proposes a method for more effective robot learning by leveraging VLMs as the sole reward, which could significantly accelerate the development of autonomous, adaptable robotic systems. It reduces the need for extensive human-crafted reward functions, simplifying robot programming and expanding their capabilities.
Robot reinforcement learning could become more efficient and less prone to 'reward hacking,' leading to robots that learn more robustly in complex, real-world scenarios. This advancement directly tackles issues of partial observability and distribution shift that currently hinder VLM-driven robot autonomy.

Robots will be able to learn complex tasks more autonomously and efficiently, reducing development time and costs.
Increased autonomy in robots will accelerate their deployment in diverse, unstructured environments, impacting manufacturing, logistics, and service industries.
The enhanced ability of robots to learn from high-level language commands could lead to more adaptive and general-purpose humanoid robots, blurring lines between human and machine labor.
