PURPOSE: A parallel robot capable of varying the length of links is provided to expand the area or a working region on a platform by varying the length of the links using a radial cam structure. CONSTITUTION: A parallel robot(100) capable of varying the length of links includes a base(110), a platform(120), and three driving arms(130). The base includes three motors, a link length varying unit, a rotation driving unit, and a case. The motors are connected to each driving end(131a) of a first arm(131). The link length varying unit is combined to the motors. The rotation driving unit rotates the link length varying unit. The driving arms are formed with first and second arms(132) connected to each other in a series. One end of the first arm is connected to the base, and one end of the second arm is connected to the platform. |
