Channel Measurements in Workspace with Robotic Manipulators at 300 GHz and Recent Results

This paper presents an initial characterization of radio channel with robotic manipulators at low terahertz frequencies. The measurement scenarios include both time-invariant and time-variant settings, reconstructing channels between two robotic arms and between an access point and a sensor node on the manipulator. The evaluation results include path gain, power delay profile and delay spread for time-invariant setups. For the time-variant setups, the evaluation results include 3D power delay profile and path gain versus time for a fixed delay value. The findings presented here demonstrate the feasibility of wireless communication in workspaces containing robotic arms and lay the foundation for further channel measurements and models development for industrial environments.
