Combining Visual and Tactile Feedback for Sub-Millimeter Precision Assembly

和中国科学院联手,具身智能企业怎么把亚毫米级“精密操作”做成绝活?

Summary

A research team from the Chinese Academy of Sciences and PaXini has developed a method that uses tactile-enhanced reinforcement learning to improve the accuracy and stability of sub-millimeter precision assembly tasks. The approach combines imitation learning for initial positioning with reinforcement learning for fine-tuning during insertion, using high-precision tactile sensors to provide critical feedback. The study, presented at IROS 2026, shows that tactile feedback significantly increases success rates in complex, visually occluded assembly scenarios.
