We propose a network-enabled platform for multiple robots. With the advance of robotics, robots penetrate into our daily lives, and the number of robots is continuously increasing. As the performance of the robots increased, the sphere of activities also increased. And this leads communication distance among robots longer. In environment with multiple robots in wide area, communication among robots become important. However, the most popular robotics system, the Robot Operating System, assumes that the network is providing a confident communication. This might lead overall system failure when master node of the system could not communicate with other nodes. Also the ROS's publish-subscribe model's anonymous communication became a barrier to efficient neighbor management. To complement the glitches of powerful system, we proposed system, DROCS, which supports network function. Further, it provides a useful high-level functions for applications which runs multiple robots. With our implementation, the proposed system achieves network management and neighbor-awareness of multiple robot system.
