InterMimic: Towards Universal Whole-Body Control for Physics-Based Human-Object Interactions

Technical Analysis Advances in humnaoids motion retargeting has shown how it is possible for humanoids to mimic humans. But how to handle the situation when the robot needs to interact with objects? Here comes "InterMimic: Towards Universal Whole-Body Control for Physics-Based Human-Object Interactions", a novel framework designed to create realistic, physically accurate, and widely applicable simulations of human-object interactions (HOIs). Analogy: The InterMimic framework is like a highly efficient tutoring center for a robot student. Instead of throwing a massive, messy textbook (imperfect MoCap data) directly at the student, the system hires specialist tutors (Teacher Policies). Each tutor focuses on mastering a small, specific chapter (data subset), fixing all the typos and errors (MoCap artifacts, retargeting issues) along the way. The student then learns from these unified, perfectly prepared lesson plans (Distilled References and Actions), allowing it to quickly master a vast curriculum of diverse skills without wasting time struggling with bad data, ultimately performing better than any single tutor. Motivation of the Work The simulation and animation of humans interacting with diverse objects is a long-standing and difficult goal in computer graphics and robotics. The difficulty stems from several key limitations in current approaches: Manual Correction is Unscalable: While Motion Capture (MoCap) data provides reference movements, it often contains significant…
