Abstract: A robot system including a first motor capable of normal and reverse rotation, a second motor capable of normal and reverse rotation and spaced apart from the first motor, pulleys coupled to rotating shafts of the first and second motors, respectively, a frame, a moving arm including a mount slidably mounted on the frame and including a free end positioned opposite the mount in a longitudinal direction, a carriage mounted on the moving arm such that the carriage is slidable in a direction perpendicular to a slide direction of the moving arm, a belt wrapped around the pulleys and connected to the carriage, and a plurality of idlers for guiding the belt. It is possible not only to control a position of the carriage by resultant force of the first and second motors but also to precisely control the carriage by the simply structured moving arm having the free end.
