Positioning and navigation system and method of indoor robot

Abstract

The invention discloses a positioning and navigation system of an indoor robot, comprising an optical label transmitter, a wireless module, a motion control module, a motion mechanism, an optical label detector, a positioning navigation module and a wireless module, wherein the optical label transmitter is used for forming an optical label on the fixed surface, and the position of the optical label in the fixed surface corresponds to the position of the robot in the motion area in a one-to-one manner; the wireless module is used for receiving navigation signals; the motion control module is used for generating corresponding drive control signals according to the received navigation signals; the motion mechanism is used for operating and driving the robot to move according to the drive control signals; the optical label detector is used for detecting the optical label and determining a coordinate of the optical label; the positioning navigation module is used for positioning the position of the robot in the motion area according to the coordinate of the optical label, and generating navigation signals according to a target position and the position planning and the corrected moving path of the robot; and the wireless module is used for sending the navigation signals. The invention also discloses a method applying the system. The method and the system are accurate in positioning, flexible in route planning and lower in cost.

Description

technical field [0001] The invention relates to the technical field of indoor robots, in particular to an indoor robot positioning and navigation system and an indoor robot positioning and navigation method. Background technique [0002] The positioning and navigation technology of indoor mobile robots is a key research hotspot in the field of indoor mobile robots. In related technology research, positioning and navigation technology is the key to realize intelligent and completely autonomous movement of mobile robots. The purpose of the research on positioning and navigation technology is to make the mobile robot move along the planned arbitrary path and complete the specified task without human intervention. [0003] Robot positioning and navigation can usually be achieved by the following methods. [0004] 1) Based on the landmarks, the robot knows where it is and the target location by recognizing the landmarks in the captured images. In this method, since the road si...

Problems solved by technology

In this method, there are high requirements for the installation of the camera, and in the case of an uncomplicated background, it is usually troublesome to achieve accurate detection

[0006] 3) Using laser or ultrasonic array, the structure is complex and the cost is relatively high

[0007] 4) Reading the electrode code disc has high requirements on the motor, and usually has a large cumulative error, and because it is not an absolute position positioning, it is not practical in the home environment
