## Summary

PNP Robotics demonstrated a dexterous hand with more than 20 active degrees of freedom that can perform rich-contact manipulation tasks such as valve rotation. Its ample actuated joints allow all five fingers to fully conform to a curved valve wheel, dynamically adjusting its grasp posture during rotation to accommodate valves of different sizes, and integrated tactile sensing enables precise contact-force adjustment to avoid slipping or jamming. The company offers a complete research kit for high-DOF dexterous hands, supporting validation of continuous-contact manipulation algorithms.
