Patent ID: 7726422

Claim:
A spherical walking robot, comprising: a spherical coronal; a spherical housing which has a surface groove and is opposite to the spherical coronal; a walking and transmission mechanism in the spherical housing; a lift and transmission mechanism connected with the spherical coronal and the spherical housing respectively, wherein the spherical coronal is operative to move close to the spherical housing to close up the spherical walking robot and is operative to move away from the spherical housing; mechanical arms located in the surface groove, wherein the mechanical arm comprises a little arm and an upper arm connected with the little arm by an elbow joint motor, the upper arm is immovably fixed on the spherical coronal, and when the spherical coronal departs from the spherical housing, one end of little arm away from the elbow joint motor is operative to rotate around the elbow joint motor and the little arm is operative to extend out of the spherical housing.
