The invention provides a novel biomimetic mechanical arm structure. According to the mechanical arm, the drawbacks are overcome that the gravity center of a traditional series mechanical arm is in the front and a device is low in stiffness. A parallel drive mode is utilized to move the gravity center backwards, therefore in the premise that the working load is constant, the load of each joint is reduced, the load of a drive device is reduced, and the cost is saved. At the same time, the joints can only swing and do not introduce coupling translation like the majority of traditional parallel mechanisms. The mechanical arm adopts biomimetic design and comprises two connecting rods swinging in space. A linear drive part is utilized to achieve three degrees of freedom motion independently swinging on the shoulder and the wrist. A rotary drive unit is utilized to achieve one degree of freedom swing at the elbow.
