1. A steering wheel structure for an omnidirectional mobile robot chassis comprising:
a rudder assembly comprising an inner ring and an outer ring;
a support plate connected with the inner ring of the rudder assembly;
a suspension assembly connected with the outer ring of the rudder assembly;
a wheel assembly, wherein the wheel assembly is installed on the support plate and located in a rotation center of the rudder assembly, the wheel assembly rotates with the support plate to provide a power for a steering wheel to move forward;
a wiring assembly, wherein the wiring assembly is installed on the support plate and located in the rotation center of the rudder assembly, the wiring assembly rotates with the support plate to constrain a motion of a power line and a signal line when the steering wheel rotates; and
the steering wheel structure comprises two degrees of freedom: a rudder rotation of a steering wheel rotation and a full free movement realized in a horizontal plane.
