A new type of hydraulic control of industrial manipulator was presented based on programmable logical controller (PLC). This design was an improvement based on the traditional spherical coordinate robot, which constituted 5 degrees of freedom (5 DOF) of hydraulic manipulator. The structure movement of manipulator was mainly driven by hydraulics, and was equipped with PLC control technology correspondingly. PLC programs were written, and the function of material handling of the assembly line in industrial manufacturing was implemented by the hydraulic manipulator. Substituion of manual operation was implemented for sorting, transport and loading and unloading. The manipulator has not only greatly reduced labor intensity of workers, but also improved labor productity.
