The invention discloses a light large-sized sea turtle robot for stage performance. The light large-sized sea turtle robot comprises a main body trunk, a control system, a leg mechanism, a neck mechanism and a turtle shell opening and closing device, wherein the movement of the leg mechanism, the neck mechanism and the turtle shell opening and closing device are controlled by the control system; the turtle shell opening and closing device comprises a turtle shell positioned above the main body trunk; the turtle shell comprises a plurality of shell pieces; the ends, positioned on the edge of the turtle shell, of the shell pieces are hinged through a supporting mechanism; each shell piece is equipped with a link mechanism for achieving opening and closing of each shell piece; a turtle shell steering engine is mounted on the main body trunk; a screw rod is directly or indirectly mounted at the output end of the turtle shell steering engine; a screw rod nut sleeves the outer surface of the screw rod; one ends of the link mechanisms are hinged to the screw rod nut, and the other ends of the link mechanisms are hinged to the shell pieces. According to the light large-sized sea turtle robot, through the arrangement of the turtle shell opening and closing device, the turtle shell can freely spread into a three-petal shape, after the turtle shell is spread, pearls placed inside can be seen, and then a smoke sprayer can spray to enhance the stage effect.
