Hi All, I am working on a monitoring tool for monitor multiple robots running ROS. The tool is working fine and I already tested using two real turtlebot robots. The next step I am planning to do is to monitor a large number of robots. I tried to use gazebo for simulate robots and it worked. I tested all avaiable robots on gazebo and the only one that publishes information on the /diagnostics and /diagnostics_agg topics was the PR2. Also gazebo requires a lot of computer resources to simulate each robot. Has anyone have any idea how to simulate more robots publishing diagnostic information ? I am wondering if create a python script for publish "random" information on the /diagnostics and /diagnostics_agg topics is a good solution or there is other ways to do the same. I am looking few examples on how to publish on diagnostic topic in python http://docs.ros.org/hydro/api/diagnostic_updater/html/ Thanks in advance, -- Best Regards, Felipe Roman Phone 55 51 8454 8110 LinkedIn http://au.linkedin.com/in/feliperoman
