Remote Two-wheel Robot control using OPC-UA

In this work, we have implemented the two networked robots that can be reproduced in real time. The two robots formed a network by applying OPC-UA and send location and heading angle information periodically between each robot for lightweight communication environment and object modeling Robot 1 is controlled by the user, and Robot 2 calculates a smoothed traveling path to move from its current position to an updated position and heading angle sent from Robot 1. The results show that the automatically-moving robot's trajectory are close to the manually controlled robot's trajectory, and the average communication delay is 20 msec or less.
