Conical robot

The invention discloses a conical robot which comprises a telescopic boom and a terminal work mechanism. The telescopic boom is formed by sequentially hinging a plurality of shear fork type units and a half shear fork type unit. Each shear fork type unit is composed of two hinge arms, wherein the middle portions of the two hinge arms are hinged through a rotating shaft. The hinge ends of the hinge arms of every two adjacent shear fork type units are correspondingly hinged together. The half shear fork type unit is composed of two half hinge arms hinged at one end. The other ends of the two half hinge arms are hinged to the hinge ends of the two hinge arms of the shear fork type unit at the outmost end. At least one of the two ends of the bottom of the telescopic boom is provided with a movable end of a telescopic driving part used for driving the telescopic boom to stretch and retract. The lengths of all the hinge arms forming the shear fork type units and the half hinge arms forming the half shear fork type
