This paper describes our work towards preliminary evaluation of LTE/5G cellular communication for robotics motion planning and control. The work comprises the development of communication architecture, motion planning and a demonstrator that validates the feasibility of the proposed approach. In the demonstrated use case, a stationary robot arm picks and places workpieces from/onto a moving mobile platform while relying only on the mobile platform's localization measurements communicated over LTE connection and not using any external sensors. We describe the approach, obtained results, shortcomings, and promising future directions.
