Cable-driven pararell robot capable of changing workspace

A cable-driven parallel robot capable of changing a workspace, the cable-driven parallel robot comprising:

• an installation frame having an upper frame defining an upper workspace, and side frames defining side workspaces;
• a plurality of driving units respectively provided on respective sides of the installation frame, each of the driving units generating forward and reverse rotational power;
• a plurality of cables installed through the driving units, each of the cables being wound or unwound by the power of its associated driving unit;
• module-direction changing standby stations provided on sides of the installation frame;
• and
• an end effector provided with a plurality of modules connected to the respective cables of the driving units, the modules being capable of performing work and moving in the upper workspace or in the side workspaces via length adjustment of the associated cables, with a coupling means provided in the modules to couple or decouple the modules to or from each other, wherein the end effector moves to the upper workspace and the side workspaces with the modules being coupled to or decoupled from each other in the module-direction changing standby stations.
