Embodiment Construction

[0027] The present invention will be further described below in conjunction with the examples, and the following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.

[0028] Such as figure 1 and figure 2 As shown, the present invention provides a mobile robot site positioning system, including a mobile robot body and a robot station. A two-dimensional code device is provided on the robot station, and the two-dimensional code device is located at the upper left of the robot station. Each two-dimensional code contains the spatial coordinates determined by this two-dimensional code and the operation information of the corresponding station. The main body of the mobile robot is provided with a positioning device and a driving module, and the driving module is used to adjust the spatial position and posture of the mobile robot and drive the movement of the robot. The ...

Abstract

The invention discloses a control method of a mobile robot field positioning system. The control method comprises the following steps: step a, setting a two-dimensional code; b, capturing a two-dimensional code pattern; c, reading the distances between three known points on the mobile robot and the plane where the corresponding two-dimensional code is located; d, calculating an angle and a distance between the collection module and a plane where the to-be-captured two-dimensional code is located; e, enabling the central axis of the image capturing device to be perpendicular to the plane wherethe to-be-captured two-dimensional code is located; f, reading the space coordinates and the operation information of the position of the two-dimensional code and the position of the two-dimensional code pattern in the image; g, calculating to obtain space coordinates of a robot collection module; and h, calculating space coordinates of the mobile robot. The invention further discloses a mobile robot on-site positioning system. According to the mobile robot on-site positioning system and the control method thereof provided by the invention, high-precision positioning in a complex constructionsite can be realized with relatively low cost, so that the mobile robot can be applied to large-scale production in a production site.

Description

technical field [0001] The invention relates to a mobile robot site positioning system and a control method thereof, belonging to the technical field of robot site construction. Background technique [0002] The current mobile robot site positioning technology mainly includes electromagnetic induction guidance, magnetic tape guidance, RFID positioning and navigation, laser guidance, inertial navigation and visual navigation. Among them, the electromagnetic induction guidance is to embed metal cables on the path of the robot and load the guidance frequency; the tape guidance is to stick a guiding magnetic strip on the path of the robot; the RFID positioning and navigation is to read the RFID tags on the path of the robot, according to The instructions in the label complete the corresponding action; laser guidance is to install a laser reflector on the driving path of the robot, and the robot emits laser and collects the reflected laser to calculate the positioning; inertial n...
