Omni-directional motion spherical robot

The embodiment of the invention discloses an omni-directional motion spherical robot which comprises a spherical shell, an arc rail, a rack and an omni-direction wheel. The arc rail is arranged in the spherical shell. The two ends of the arc rail coaxially penetrate through and are supported on the diameter of the spherical shell. The rack is arranged in the spherical shell. The upper portion of the rack is supported on the arc rail through rail wheels and guide wheels. The omni-direction wheel is installed at the bottom of the rack. According to the technical scheme, the robot has the following advantages that the characteristic that the omni-directional wheel can roll in two directions at the same time is used to drive single eccentric mass in a sphere, and the omni-directional motion spherical robot is obtained; movable element mass is far away from the sphere center, and maneuverability and power efficiency of the spherical robot are enhanced to the largest extent; the rack is located below the arc rail so that the posture of the robot can be well recognized, and convenience is brought to intelligent control; the structure is simple, high-precision parts are not needed, and accordingly engineering cost can be reduced.
