Embodiment Construction

[0047] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.

[0048] As shown in Fig. 1 structural block diagram of the present invention comprises:

[0049] The navigation network 1 has: n wireless access points AP1-APn connected wirelessly, forming mutual communication and realizing a shared network system, where n is a natural number. The implementation of the wireless access point adopts the ZigBee specification, that is, IEEE 802.15.4 or the WLAN specification, that is, IEEE 802.11x (x can be a, b, g or n) or a non-standard custom protocol under the ISM frequency band, and the antenna adopts an omnidirectional antenna. The layout of wireless access points is related to the positioning accuracy requirements of the robot, the size of the coverage area of ​​the navig...

Abstract

The utility model discloses a robot navigation system and a navigation method. The robot navigation system comprises a navigation network which is formed by a plurality of wireless access points, a wireless communication module which is used for transferring data and collecting the intensity sequence communicated with the wireless access points, a sensor which is used for checking that the robot meets barriers or not, and a position server which is used for storing the referenced intensity sequence and running the intricate position arithmetic, and is characterized in that the position server is connected with the wireless communication module and interacts with the navigation network. The navigation method is characterized in that the robot judges the next target position until reaches the destination by comparing the intensity sequence collected in real time with stored reference intensity sequence of the position points; when the robot meets barriers, the robot records and demarcates the intensity sequence of the position in order to avoid entering the position again, therefore achieving intellectual learning; the robot can upload the correlative information to the position server and achieve the assistant navigation position by the help of the database of the position server and the position arithmetic. The utility model is not likely to be affected by the environment and also has the advantages of low cost of maintenance.

Description

technical field [0001] The invention belongs to the technical field of robots, and relates to a robot navigation system, which is used for robot positioning and automatic navigation in an environment where wireless access points can be installed. Background technique [0002] Mobile robot navigation is a system and method that realizes that the robot system relies on sensor technology and artificial intelligence technology to move from the starting point to the destination point in a complex environment. Common navigation methods include electromagnetic navigation, light reflection navigation, visual navigation, and taste navigation. [0003] Electromagnetic navigation is also called underground buried line navigation. Its principle is to continuously bury multiple guiding cables on the path, flow currents of different frequencies respectively, and sense the path information through the detection of the current by the induction coil. The cost of this technology is high, and...
