Problems solved by technology

In the front wheel steering method, the robot can achieve balance only by relying on its own structure, but it must rely on the interaction between the ground and the robot wheels, which is greatly affected by the terrain and the speed of the robot.
In the center of gravity adjustment method, the self-balanci

Embodiment Construction

[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

The invention provides a self-balancing two-wheel robot comprising a support body, a front wheel, a rear wheel, a steering drive element, a first advancing drive element, a gyro unit and a deflection drive element. The front wheel and the rear wheel are connected to the support body. The steering drive element is arranged on the support body and connected to the front wheel. The first advancing drive element is arranged on the support body and connected to the rear wheel for driving the rear wheel to rotate. The gyro unit comprises a fly wheel, a frame, a rotation drive element, a deflection shaft, a bearing base and an angle sensor, wherein the bearing base is arranged on the support body and the deflection shaft is connected to the bearing base. The deflection drive element is arranged on the bearing base and connected to the deflection shaft. The angle sensor is arranged on the bearing base and connected to the deflection shaft. The frame is connected to the bearing base through the deflection shaft. The fly wheel is connected to the frame. The rotation drive element is arranged on the frame and connected to the fly wheel for driving the fly wheel to rotate. The self-balancing two-wheel robot is characterized by high response speed and large corrective torque.

Description

technical field [0001] The invention relates to the field of mobile robots, in particular to a self-balancing two-wheeled robot. Background technique [0002] The front and rear two-wheeled robots are long and narrow, with flexible movements. The two-wheeled robot is suitable for high-speed driving on narrow roads and can adapt to complex road conditions, especially in road conditions with large undulating terrain. However, when the above-mentioned two-wheeled robot is in motion, there is a tendency to incline to the left and right sides of its advancing direction, so the two-wheeled robot needs to be self-balancing. The current self-balancing technology includes the front wheel steering method, the center of gravity adjustment method and the reaction moment method. In the front wheel steering method, the robot can achieve balance only by its own structure, but it must rely on the interaction between the ground and the robot wheels, which is greatly affected by the terrain ...
