Summary

This paper introduces CHORD, a framework that enables robots to learn complex, long-horizon dexterous manipulation tasks from human demonstrations using reinforcement learning. It employs object-centric contact wrench space guidance to measure motion similarity and scales effectively across a large simulation benchmark, also transferring to real-world applications.

Teaching robots complex, dexterous manipulation skills, especially those involving contact with objects, remains a significant challenge. While human demonstrations offer a rich source of data, effectively transferring these skills to robot policies is difficult. Researchers have developed a new framework called CHORD (Contact Wrench Guidance from Human Demonstration in Robotic Dexterous Manipulation). CHORD addresses this by representing both human and robot motions through the forces and torques they exert on an object, allowing for a more precise measurement of motion similarity. This "contact wrench space guidance" makes reinforcement learning more scalable for intricate, contact-rich tasks. The framework was evaluated on a massive simulation benchmark of nearly 5,000 bimanual manipulation tasks, achieving high success rates. CHORD also demonstrated generalization to whole-body manipulation and successful transfer of learned policies to real-world robots, both in open-loop and closed-loop control.

Why it matters

This advancement significantly improves the ability of robots to perform complex, human-like manipulation, opening doors for automation in industries requiring fine motor skills and intricate object handling. Professionals can anticipate more versatile and capable robotic systems.
