Abstract : An artificial limb is required to provide movement to manage an amputee's daily vital life. The mechanical design and simulation of an anthropomorphic multi-fingered soft prosthetic hand with 5 degrees of freedom are discussed in this study. The suggested design features 5 fingers, each of which is driven directly by two flexible hydraulic actuators (FHAs). With FEA analysis, the asymmetric flat FHA made of nitrile butadiene rubber achieved a good bending deflection of 84 degrees at 6 bar operating pressure. The simulation findings from ANSYS reveal that the bending of FHA is affected by the shape profile of the chamber and the proportion ratio of top chamber thickness to the bottom plate thickness. Myoelectric data gathered from three sensor electrodes inserted on to the surface of the forearm muscles governs the open and closure actions of fingers. With the aid of a microcontroller, a MyoWare sensor is used to plot the EMG graph. SOLIDWORKS software is used to simulate the grasping abilities of the hand while holding diverse shapes of things.
