Abstract
Currently, available 5G modules are mostly installed on larger development kits, require a microcontroller as middleware, and thus do not have a compatible interface that enables simple integration into systems, machines, or robotics as a plug-and-play solution, similar to a Wi-Fi USB stick. For the application of 5G in the field of robotics, however, it is important to have modules that are as light and small as possible, provide easy integration, and fully deliver the capabilities of 5G. Therefore, our paper presents a small and lightweight 5G communication adapter in which a 5G-radio module is mounted on an M2 carrier board and can be connected via USB to any compatible device. For testing purposes, the communication adapter is presented in an Unmanned Aerial Systems (UAV) application that depends on time-critical communication. The test environment is equipped with motion capture cameras that are used to determine the position of the UAV. ROS2 acts as middleware for communication between the various interfaces, specifically the development computer, the drone's companion computer, and the motion capture system. Subsequently, the measured communication values and resulting flight behavior are presented in detail. As a result of the data collected, the resulting benefits, limitations, and possible improvements to the UAV application and high-speed robotics applications using 5G technology are discussed.
