Closed-Loop Telerobotics over Software-Defined Radio based 5G Wireless Testbed

The evolution of 5G and beyond wireless communications and upcoming 6G communications have enabled many critical applications. Telerobotics over tactile Internet is one such application that involves ultra-low latency for its control and also needs bandwidth-intensive visual or multi-sensory feedback to the remote control center for critical operations involving human-in-the-loop. In this study, we have conducted an experimental evaluation of closed-loop telerobotic operations over a software-defined radio (SDR) based 5G wireless testbed and demonstrate the advantages and limitations of the current SDR technology in context of these applications.
