Robust and Expressive Humanoid Motion Retargeting via Optimization-Based Rig Unification

IROS 2025

Humanoid robots are increasingly being developed for seamless interaction with humans in diverse domains, yet generating expressive and physically-feasible motions remains a core challenge. We propose a robust and automated pipeline for motion retargeting that enables the generation of natural, stab
