The invention relates to a deformed robot, which is composed of screw propellers, a signal receiver, deformed wheels, an electric telescopic rod, a chassis, a bracket, a bearing, big and small gears,a small motor, a transmission shaft, a remote controller and a spherical spoke shell, wherein the shell is of a spherical structure, and the spherical structure can be deformed into an ellipse, so that the volume is diminished; the screw propellers are arranged in the spherical spoke shell, and the motor part, which is provided with a storage battery, can be charged and discharged; the bottom of the deformed robot is composed of the three deformed wheels, and the wheels, which are deformed, function as the screw propellers, so that the deformed robot can walk in water; the robot has triple functions; such detectors as a camera and the like can be carried; the deformation and moving direction of the robot are controlled by virtue of the remote controller; and such tasks as detecting, searching-and-rescuing and the like are completed in complex terrains and scenes of fire. The robot provided by the invention can be prevented from getting damaged due to collision by virtue of the spherical spoke shell; and the spherical spoke shell can be also deformed into the ellipse, so that the volume is diminished and carrying is facilitated.
