2017-01-11 17:10:57 -0500 asked a question rotors_simulator and mavlink

How does the gazebo_mavlink_interface plugin in rotors_simulator interact with the rest of ROS? I'm enabling the mavlink interface when I spawn the URDF for the drone, but it doesn't seem like there are any topics exposed by the plugin even though it is supposed to do something with /mavlink/from.

2016-11-23 21:07:17 -0500 asked a question Is ROS the best way to communicate with an autonomous robot?

I have a robot that I want to send occasional commands to, e.g. go to all these waypoints, return to home base, etc. It seems like ROS topics/actions are not a good fit for the link from the base station to the autonomous robot because the underlying hardware link is unreliable (wireless) and the robot is almost guaranteed to be outside comms range at least some of the time. This would mean that either the robot or the base station would lose connection to the ROS master.

Does it make sense to start up another service like a webserver to handle the communication between the base station and the robot, or is there some better way of handling communications between the base station and the robot? There doesn't seem to be a particularly idiomatic way to do this.
