No Eyes, No Problem: What Does Touch Contribute to Blind Baoding Ball Manipulation?
The study combines sensor-aligned embodiment, tactile calibration, and novel domain randomizations to bridge the sim-to-real gap, setting a new benchmark for tactile-driven dexterous manipulation.
This paper demonstrates a significant advancement in tactile-driven dexterous manipulation by achieving sustained blind Baoding ball rotation on a physical hand using only proprioception and binary tactile feedback. The results highlight the effectiveness of sim-to-real transfer through sensor-aligned embodiment, tactile calibration, and novel domain randomizations.

e to proprioception alone and identify the hand regions where tactile information is most important. This is the strongest reported hardware result for Baoding ball manipulation in both rotation count and speed, irrespective of the sensing modality used. By effectively bridging the sim-to-real gap, our framework sets a new benchmark for sustained tactile-driven dexterous manipulation on physical hardware.
