Embodiment Construction

[0018] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0019] Embodiments of the present invention provide a robot indoor positioning and autonomous navigation system and method.

[0020] Please refer to figure 1 , figure 1 It is a structural diagram of a robot indoor positioning and autonomous navigation system in an embodiment of the present invention. The indoor ground is laid in advance as a whole figure 2 In the shown 20KHz mesh alternating magnetic field track, the intersection of the mesh alternating magnetic field track is a node, and the side length of the mesh structure is small, that is, the distance between two adjacent nodes is small. In this embodiment, The distance between two adjacent nodes is 1m; each node is installed with a small IC card that can be re...

Abstract

The invention provides an indoor positioning and autonomous navigation system for a robot. The system comprises adopting an RFID reader-writer to identify an IC card preset on the ground so as to determine the current position coordinate of the robot; adopting induced electromotive force generated by a 20 kHz alternating magnetic field laid by four-path inductance identification as a path navigation signal; utilizing ultrasonic waves to detect whether an obstacle exists in front of the robot or not in real time, so that the obstacle detection and avoidance of the robot in the navigation process are realized; and performing human-computer interaction by combining voice recognition and voice playing, and finally realizing autonomous navigation transmission. The indoor positioning and autonomous navigation system for robot has the advantages that the autonomous navigation capability of the system is enhanced, the system cost is reduced, the marketing realization is facilitated, and the system has better industrial value and application prospect.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a robot indoor positioning and autonomous navigation system. Background technique [0002] At present, outdoor positioning and navigation are mainly realized by GPS, and the camera realizes the collection and processing of environmental information. However, since GPS can only achieve several-meter-level positioning, it is only suitable for positioning and navigation in a large area, and the GPS signal is weak indoors, so it cannot work normally; when the camera collects environmental information, it has higher requirements for the central processing unit. , the algorithms involved are relatively complex, the operating cost is high, and it is easily affected by light. It is difficult to work normally when there is occlusion indoors. [0003] For now, there is a great demand for road guidance for people inside large public facilities, large hotels, factories and other large build...
