ABSTRACT:
A robot includes: a base; a column installed to the base; a first arm of which one end is rotatably coupled to the column and having at least one through hole; a second arm pivotally coupled to the other end of the first arm and having at least one through hole; a third arm installed to be capable of rotating and moving up and down with respect to the second arm; first and second driving portion, installed at the first arm, for driving the first arm and the second arm, respectively; third driving portion, installed at the second arm, for driving the third arm; and a cable extended through a cavity formed inside the base, the column, the first, second and third arms and connected to the first, second, and third driving portion through the respective holes formed in the first and second arms. Thus, generation of dust due to friction between the cable and the robot can be prevented.
