Embodiment Construction

[0040] The solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] Such as figure 1 Shown, the mobile robot navigation control method based on GPS positioning comprises the following steps:

[0042] Step 1. The main control board receives the positioning information (longitude, latitude) of the target point through the wireless communication module, reads the current positioning (accuracy, latitude) and the direction angle of the robot head sent by the positioning module, and stores them. Such as figure 1 As shown, it specifically includes the following steps:

[0043] Step 1-1. The precise positioning information of a point is known, and it is selected as the target point. After the point information is input in the control terminal, it is sent to the main control board through the wireless communication module, and the main control board stores it for future use.

[0044] Step 1-2. ...

Abstract

The invention discloses a navigation control method for a mobile robot based on GPS positioning, which obtains the current positioning of the robot, the direction angle of the head of the robot and the positioning of a target point; and calculates the angle between the line connecting the two and the horizontal axis according to the current positioning of the robot and the positioning of the target point , combined with the direction angle of the robot’s head, calculate the operating parameters of the motor; according to the operating parameters of the motor, drive the motor to rotate forward and reverse within the set time; update the operating parameters of the motor to drive the motor until the robot reaches the target point within the threshold range. The invention simplifies the experiment process, and only needs to complete the point-to-point navigation control without planning the path in advance, thus improving the timeliness of robot navigation.

Description

technical field [0001] The invention relates to mobile robot control technology, in particular to a GPS positioning-based mobile robot navigation control method. Background technique [0002] With the continuous advancement of science and technology, the application of robots has become more and more extensive, and has penetrated into almost every field. In the field of robot control, the navigation control of mobile robots is a crucial part. Both enterprise product design and university robot control experiments are based on the navigation control of mobile robots, such as intelligent inspection robots in large substations, intelligent car automatic driving technology, and so on. Existing navigation control methods have a high technical threshold, are difficult to implement, and require a lot of manpower and material resources. However, experimental teaching in colleges and universities does not require high navigation accuracy, and using existing navigation control techno...
