Problems solved by technology

Although the general non-omnidirectional wheeled mobile robot can achieve any direction and position after attitude adjustment in an open working space, it is no longer applicable in a relatively narrow space because it does not have the ability to move laterally.

Abstract

The invention relates to a driving mechanism of an omnidirectional mobile robot. The existing driving mechanism has low degree of freedom. A substrate is provided with a rotation driving motor; the rotation driving motor drives a driving rotation measuring wheel and a driving rotation driving wheel; a coder is installed below the driving rotation driving wheel; the driving rotation driving wheel is connected with a driven rotation driving wheel through a rotation driving belt; the driven rotation driving wheel is installed in a bearing between an upper cover and a lower cover; the rotation driving wheel drives a rotation axis; the bottom of the rotation axis is fixedly connected with a wheel bracket; the wheel bracket is internally provided with a rolling wheel; and the up-and-down movement of the wheel bracket is finished by the combined action of a damping spring and the rotation axis. The rolling wheel has three degrees of freedom, and the adaptability to landforms is increased on rough terrain.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a transmission mechanism of an omnidirectional mobile robot. Background technique [0002] Wheeled mobile robots have been widely used due to their advantages such as good stability and fast mobility. Omnidirectional mobile robot is a special form of wheeled mobile robot. The omni-directional mobile robot can move in any direction while keeping the posture of the body unchanged, and realize the function of omni-directional movement. This feature makes the path planning and trajectory tracking of the mobile robot relatively simple. Although the general non-omnidirectional wheeled mobile robot can achieve any direction and position after attitude adjustment in an open working space, it is no longer applicable in a relatively narrow space because it does not have the ability to move laterally. In this case, the omnidirectional mobile robot can take advantage of its stru...
