Any2Any: Efficient Cross-Embodiment Transfer for Humanoid Whole-Body Tracking

ai-technology · 2026-05-25

The Any2Any framework introduces a novel method for the effective transfer of pretrained whole-body tracking (WBT) models among various humanoid robot designs, requiring minimal data and computational resources. Detailed in arXiv paper 2605.23733, Any2Any begins with kinematic alignment between the source and target humanoids to synchronize their input and output spaces, enabling the reuse of the source policy. Subsequently, it utilizes lightweight parameter-efficient fine-tuning (PEFT) for adapting dynamics-sensitive components. This strategy mitigates the significant expense associated with training WBT models from the ground up for each new platform, thereby promoting swift deployment.
