Researchers have developed PRIMO R1, a 7B framework that enhances robotic manipulation by transforming video MLLMs from passive observers into active critics. This system uses reinforcement learning to encourage explicit Chain-of-Thought generation for progress estimation, anchored by initial and current state images. Experiments show PRIMO R1 achieves state-of-the-art performance, reducing mean absolute error by 50% compared to specialized reasoning baselines and outperforming larger general MLLMs. It also demonstrates strong zero-shot generalization on failure detection tasks, surpassing models like OpenAI o1 on the RoboFail benchmark.
