A Smart Fluid-Hydraulic System Based on MRF Valve Control and Its Application in Flexible Grasping. [PDF]
Adv Sci (Weinh)This study introduces a smart fluid hydraulic system using MRF valve control for flexible gripping. An MRF‐MSV with an integrated excitation coil and micro‐textured damping channels is designed and validated; micro‐texturing increases hydraulic resistance. Coupled with a soft actuator, the MRF‐MSV enables dynamic bending and grasping.
