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-balancing equipment has a simple structure and is easy to control, but due to the need to adjust the position of the mass block, the robot responds slowly
In the reaction moment method, the self-balancing equipment has a relatively simple structure and fast response speed, but the robot cannot withstand large impacts

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 discloses a self-balancing two-wheel robot. The self-balancing two-wheeled robot includes a supporting body, a front wheel, a rear wheel, a steering drive element, a first travel drive element, a gyro component and a deflection drive element. Both the front wheel and the rear wheel are connected to the supporting body, the steering drive element is arranged on the supporting body and connected to the front wheel, and the first travel driving element is arranged on the supporting body and connected to the rear wheel for driving the rear wheel to rotate. The gyro part has a flywheel, a frame, a rotating drive element, a deflection shaft, a bearing seat and an angle sensor. The bearing seat is installed on the support body, the deflection shaft is connected to the bearing seat, the deflection drive element is arranged on the bearing seat and connected to the deflection shaft, and the angle The sensor is arranged on the bearing seat and connected to the deflection shaft, the frame is connected to the bearing seat through the deflection shaft, the flywheel is connected to the frame, and the rotation driving element is arranged on the frame and connected to the flywheel for driving the flywheel to rotate. The self-balancing two-wheel robot has fast response speed and large correction 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 ...
