Jet spherical robot

The invention discloses a jet spherical robot which comprises a spherical shell and an internal movement mechanism. The spherical shell is connected with the movement mechanism by bearings, and the movement mechanism and the spherical shell can rotate around a horizontal center line. The spherical shell is of a non-sealed structure in the shape of a mesh cage. The movement mechanism comprises two ducted fans, support frames and a counter weight. The two ducted fans are equidistantly mounted on two sides of the longitudinal section of the jet spherical robot, and the counter weight is connected onto the support frames by a rigid rod. When the jet spherical robot moves and the two ducted fans rotate at equal speeds and generate identical thrust, the counter weight is pushed by the thrust, the gravity center of the internal movement mechanism is changed, the spherical shell quickly rotates along the horizontal center line, and accordingly the jet spherical robot can move forwardly; when the two ducted fans rotate at unequal speeds and generate high thrust and low thrust, deflection torque is generated while the spherical robot moves forwardly, and accordingly the robot can turn a corner along the vertical direction. Compared with the traditional spherical robot in a motor driving mode, the jet spherical robot in a jet propulsion mode has the advantages that the jet spherical robot is simple and light in structure, the maneuverability of the robot is greatly improved, and the like.
