What Matters When Cotraining Robot Manipulation Policies on Everyday Human Videos?
Researchers have investigated the effectiveness of using everyday human videos to train robot manipulation policies. They found that while accurate hand poses improve transfer learning, a significant "motion gap" between human and robot movements still hinders performance. To bridge this gap, they developed a cotraining method that specializes vision and policy networks for each embodiment, leading to a notable $29.7\%$ increase in success rates for robot manipulation tasks with limited robot-specific data.
