Abstract:Aiming at the problems of complex structure, high cost and poor tactile perception of traditional mechanical imitation hand, a kind of artificial hand driven by electromagnetic moving pulley was designed. Through the double-stage drive wire rope and electromagnetic dynamic pulley cross vertical way, the independent drive control of a drive motor to 5 fingers 6 degrees of freedom was realized.Through the serial winding connection between double finger joints and cross pulley, each finger joint had the relative independence of drive, and the passive adaptability of finger to object shape was improved.An elastic light device was developed and it was placed inside the finger joints and palm to provide corresponding restoration.Through study on its bending and load characteristics,the mathematical model of the angle and load was established,the finger pressure and joint corner detection were realized.The performance testing of the prototype was implemented.It is shown that it can realize grabbing to common items.
