Rope drive type mechanical arm based on coupled linkage

The invention relates to the technical field of mechanical arms, in particular to a rope drive type mechanical arm based on coupled linkage. A base, a mechanical arm body, a transmission rope assemblyI, a transmission rope assembly II and an input rope drive assembly are included, wherein the mechanical arm body is arranged on the base and can rotate relative to the base. The transmission rope assembly I and the transmission rope assembly II are arranged on the mechanical arm body and used for driving the mechanical arm body to rotate forwards and reversely. The input rope drive assembly is arranged on the base and used for controlling the transmission rope assembly I and the transmission rope assembly II to act. According to the rope drive type mechanical arm, the coupled linkage form isadopted between various units to transmit motions, the number of drive sources is greatly reduced, meanwhile, control is simple, operation is convenient, and the size of a rope drive type mechanicalarm pedestal is reduced. 本发
