A Vision of XR-aided Teleoperation System Towards 5G/B5G

Abstract

Extended Reality (XR)-aided teleoperation has shown its potential in improving operating efficiency in missioncritical, rich-information and complex scenarios. The multisensory XR devices introduce several new types of traffic with unique quality-of-service (QoS) requirements, which are usually defined by three measures-human perception, corresponding sensors, and present devices. To fulfil these requirements, cellularsupported wireless connectivity can be a promising solution that can largely benefit the Robot-to-XR and the XR-to-Robot links. In this article, we present industrial and piloting use cases and identify the service bottleneck of each case. We then cover the QoS of Robot-XR and XR-Robot links by summarizing the sensors' parameters and processing procedures. To realise these use cases, we introduce potential solutions for each case with cellular connections. Finally, we build testbeds to investigate the effectiveness of supporting our proposed links using current wireless topologies.
