Virtualization of services in factory production allows achieving higher service reliability and smaller cost of industrial equipment. The demonstrator shows Mobile Edge Cloud (MEC) implementation for services such as path planning and movement control of a robot arm, collaboration between two robot arms, and remote control of a robot arm. The audience can participate in the demonstrator through guiding a robot arm remotely using a wireless controller. The MEC resources required for such virtualized services are shown in terms of traffic (throughput and inter-arrival time) and server load.
