Researchers have developed a self-supervised method to fine-tune Vision-Language-Action (VLA) models, such as $π_{0.5}$, for improved performance on new robotic embodiments. This approach generates additional training data from the model's own zero-shot interactions, addressing performance drops caused by hardware mismatches. Experiments on the ALOHA robot and RoboTwin simulation benchmark demonstrate that this fine-tuning scheme enhances multi-task policies, preserving original instruction-following capabilities while efficiently learning new skills.
