I have a few robots powered by a Jetson TX2 boards running ROS, and I would like to communicate with them securely over wifi. I don’t have a lot of networking experience, and am using this project as a means to force myself to learn. I was wondering if you all have some suggestions on technologies I should look at.
The RobotCloudServer caught my eye, can that do point-to-point communication or does it need to go though a router? Is my understanding correct that it runs on top of an existing VPN connection set up through OpenVPN? Also it suggests using RMS which also requires rosbridge. Is RMS worth using too?
Before I go down the rabbit hole installing a wide variety of technology, I was wondering what you all have had success with in the past.
