A precision robot apparatus (10) is disclosed which has an arm supporting cylinder (16) capable of being moved vertically by means of a lead screw (24) which rotates within a lead screw nut (38) attached to the arm supporting cylinder (16). A linear guide rod (44) is positioned parallel to the arm supporting cylinder (16) with an anti-rotation plate (42) therebetween. An arm drive belt (74) transfers rotational power from the linear guide rod (44) to the arm supporting cylinder (16). Rotational motion of the arm supporting cylinder (16) relative to a fixed arm pulley (92) is employed to power an arm portion (14).
