Abstract
A mobile platform including a body, hybrid leg-wheels and driving mechanisms is provided. The hybrid leg-wheels are disposed around the body for carrying the body moving on a working surface. The driving mechanisms are disposed between the corresponding hybrid leg-wheels and the body. Each driving mechanism includes a driving axle connecting the corresponding hybrid leg-wheels and the body. Each driving mechanism provides the corresponding hybrid leg-wheel a rotational degree of freedom and a translational degree of freedom, wherein the rotational degree of freedom and the translational degree of freedom are driven independently. The rotational degree of freedom allows the hybrid leg-wheels rotating along an axis of the driving axle, and the translational degree of freedom allows the hybrid leg-wheels translating relative to the driving axle, wherein the rotational direction is substantially perpendicular to the translational direction.
