Proprioception-Anchored Cross-Modal Pretraining for Zero-Shot Sim-to-Real Assembly
The paper introduces a pretraining method that uses proprioceptive signals as an anchor to align different sensory modalities, aiming to help robots handle contact-rich assembly tasks. Such tasks demand submillimeter precision and accurate force interpretation during sustained contact, which makes sim-to-real transfer difficult. The approach targets zero-shot deployment of policies trained in simulation onto real hardware. This is a replacement listing on arXiv cs.AI.
