STEERING WHEEL STRUCTURE FOR AN OMNIDIRECTIONAL MOBILE ROBOT CHASSIS

A steering wheel structure for an omnidirectional mobile robot chassis is provided. The steering wheel structure can realize two degrees of freedom: the rudder rotation of the steering wheel rotation and the full free movement realized in the horizontal plane, it has the characteristics of a small size and a lower height. The wheel assembly realizes the movement of the steering wheel when it moves forward; the rudder assembly realizes the movement of the steering wheel when the steering wheel rotates, initializes the steering direction, and calibrates the rotation through the zero position sensor; the suspension assembly realizes the damping and buffering of the longitudinal motion of the steering wheel; the wiring assembly constrains the movement of various wires when the rudder rotates; the support plate is used for the connection and support of the wheel assembly and the wiring assembly with the rudder assembly.
