The gear train assembly is installed under the machine frame assembly, the steering and moving assembly is used for driving steering and horizontal moving of the gear train assembly. When a carrier is installed on a machine frame, movement of the gear train assembly is transmitted by transition pieces, and driving force of the transition pieces is realized by cooperating two motors in the steering and moving assembly, four synchronous belts and eight belt wheels, thereby ensuring stable steering and moving of the machine frame. The steering of the base mechanism is completed by individual driving of a first stepping motor, and the moving of the base mechanism is completed by the individual driving of a second stepping motor. The base mechanism is capable of realizing steering and moving functions only through the two motors and enabling two movements to be fully decoupled and is easy to control.
Description
Technical field
The utility model relates to a kind of base of using on the robot that is applicable to, more particularly says, is meant a kind of wheeled robot base mechanism that can pivot stud.
Background technology
Wheeled robot steering hardware commonly used mainly contains five kinds: Ai Keman turns to, differential steering, axle-articulated type turn to, four-wheel steering and car body-articulated type turn to.It is most typical method that Ai Keman turns to, and it is by back-wheel drive, and front-wheel is driven and turn to, and connects by Ai Ke Man U to make front-wheel realize synchronous deflection between two wheel flutters, similar with vehicle steering principle such as automobile.The both sides wheel individual drive of differential steering realizes turning to of different radii by changing the both sides wheel velocity.It is that the rotation of the axle by connecting the both sides wheel realizes turning to that axle-articulated type turns to, and turns to differently with Ai Keman, and wheel itself does not rotate around longitudinal axis.In the four-wheel steering mode, each wheel can be realized comprehensive the turning to of 360 degree of any one wheel by an independently steer motor driving.Car body-articulated type turns to mostly to be made up of two sections car bodies, connects by S. A. between two sections car bodies, and all there is the fixing wheel of direction every section car body both sides, realizes turning to by means of the rotation of certain section car body with respect to another section car body.
