Global robot driven by jump gear

The invention provides a global robot driven by a jump gear. The problems that moment driven by a gravity pendulum of a common global robot is over large, and the common spherical robot which is driven by a trolley easily slips on the inner wall of a sphere are solved. The global robot driven by the jump gear consists of a sphere, a linear driven jump gear subassembly, a steering driving lead screw subassembly and a hollow spindle subassembly, wherein the hollow spindle subassembly is connected with the sphere through two rolling bearings; a balance weight platform in the linear driven jump gear subassembly is fixedly connected to the hollow spindle subassembly; a gear driving component in the linear driven jump gear subassembly is arranged under the balance weight platform; the linear driven gear is meshed with an inner gear ring; the inner gear ring is fixedly connected with the sphere; and the steering driving lead screw subassembly is fixedly connected with the hollow spindle subassembly.
