PURPOSE: A telescope shaped robot is provided to precisely control a vertical displacement of driving frames by an operating structure of a rack and pinion. CONSTITUTION: A telescope shaped robot comprises: a drive motor for elevating(60) which is installed on the first driving frame(20) which is next to a base frame(10); a elevating member which elevates the first driving frame by receiving driving force from the drive motor and elevates the second driving frame which is next to the first driving frame; a driven rotating shaft(80) which is rotatably supported on the driving frames(30) except the first driving frame; a first and a second pinion gears(81,82) which are installed on the both ends of the driven shaft; and driven rack members(83,84) which is coupled to the first and the second pinion gears.
