Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] It should be noted that if there is a directional indication in the embodiment of the present invention, the directional indication is only used to explain the relative positional relationship and movement conditions between the components in a specific posture. If the specific posture changes , then the directional indication changes accordingly.

[0033] In addition, if there are descriptions involving "first", "second" and so on in the embod...

Abstract

The invention discloses a mobile robot chassis which comprises a chassis body, a wheel assembly, a linkage mechanism and a first driving device, the wheel assembly comprises a plurality of wheels, andeach wheel can be horizontally and rotationally installed at the bottom of the chassis body around the vertical axis; the linkage mechanism is respectively connected with the plurality of wheels; andthe first driving device is in driving connection with the linkage mechanism and is used for driving the plurality of wheels to synchronously steer through the linkage mechanism. Synchronous and same-direction rotation of the plurality of wheels is achieved, the plurality of wheels are made to be in a pure rolling state during turning, transverse movement and in-situ rotation can be achieved, andthe stability and flexibility of the robot are greatly improved.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a mobile robot chassis. Background technique [0002] The use of robots has profoundly affected my country's manufacturing, scientific research and service industries. There are many types of mobile robots, and land mobile robots include mobile, legged, crawler, and jumping types. Among them, the wheeled mobile robot has been widely used due to its advantages of convenient movement, accurate positioning, and convenient control. There are two common structures, three-wheel and four-wheel. Three-wheeled robots are simple in structure, but have low stability and often run at low speeds. Three-wheeled robots with omni-directional steering mostly use omni-directional wheels. Four-wheeled robots also have structures such as two-wheel steering two-wheel drive, four-wheel steering four-wheel drive, etc. The four-wheeled robot with all-round steering mostly uses mecanum wheels.
