Example Embodiment

[0027] Such as figure 1 Shown is a block diagram of an indoor robot positioning and navigation system according to an embodiment. The positioning and navigation system 10 includes a freely movable robot 100 and a fixed positioning navigator 200. The robot 100 moves freely in its motion area, and the positioning navigator 200 locates and navigates the robot 100.

[0028] The robot 100 includes a light marker transmitter 101, a wireless module 102, a motion control module 103 and a motion mechanism 104.

[0029] The light mark transmitter 101 is used to emit light to the fixed surface 300 to form a light mark. When the robot moves, the light mark transmitter 101 is driven to move, and the position of the light mark on the fixed surface 300 also moves accordingly. The position of the light mark on the fixed surface 300 corresponds to the position of the robot 100 in its movement area, so that by determining the position of the light mark on the fixed surface 300, the position of the ...

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...
