Description

Autonomous Driving Robot Operation System and Method Using UWB Network Embodiments of the present invention relate to an autonomous driving robot operating system and method using an Ultra-Wide Band (UWB) network. Ultra-wideband (UWB) technology utilizes a wide frequency band and is ideally designed to operate in a transmission power environment that does not interfere with existing wireless systems. For this reason, it was originally developed for military purposes; although the transmission distance was short at the time of development (approximately 10m), technological advancements have enabled transmission distances of over 100m, allowing for applications in various fields. Recently, with the development of artificial intelligence and the expansion of the Internet of Things, there has been a need for ultra-wideband technology capable of precise location measurement without being constrained by obstacles in indoor spaces. Meanwhile, service robots in modern society are distinguished from industrial robots used in manufacturing; they are utilized not only in personal fields such as education and household support but also in specialized sectors like healthcare, rescue and security, and national defense, with their utility continuously on the rise. One of the reasons for the increased interest in service robots is the advancement of autonomous driving technology. Service robots are being used for various purposes in diverse indoor spaces, such as hospitals, airports, and factories, including delivering goods and guiding visitors. Autonomous robots operating indoors require an internet connection to communicate with a server. By connecting to the server, the robot transmits the platform's location and status, and through the server, it can receive destination and movement commands. Wireless mobile communication networks are used to connect these robots to the internet, but this presents the problem of incurring periodic charges to telecommunication companies. The technology forming the background of the present invention is disclosed in Korean Registered Patent Publication No. 10-2484732 (January 2, 2023). FIG. 1 is a block diagram of an autonomous driving robot operating system using a UWB network according to one embodiment of the present invention. FIG. 2 is a diagram illustrating the operation of a robot control server communicating with an autonomous driving robot using a UWB network according to an embodiment of the present invention. FIG. 3 is a flowchart illustrating a method for operating an autonomous driving robot using a UWB network according to an embodiment of the present invention. FIG. 4 is a flowchart illustrating the process of controlling the autonomous driving of a robot through a UWB network according to one embodiment of the present invention.
