Hi everyone! Here at the university we use groups of simple robots instead of a single, more complex robot, like the PR2. We have currently been taking the first steps into ROS. It became clear that we will need a ROS communication node so that our robots can speak to each other. So here is my question, does anyone have any experience with multiple-robot communication in ROS? We are considering a communication node based on UDP sockets capable of exchanging ROS msgs. Does anyone have any thoughts on this matter? Gonçalo Cabrita ISR - University of Coimbra Portugal
