What happens if you lose a sensor and the robot starts spinning in place at top speed or takes off down the hall? What happens if you have a stroke and fall forward on the joystick? What if the connection is laggy and you have choppy video and can only control the robot in 1/2 second intervals? (That's happened in matches on FRC fields.) Have you disabled those "annoying" MotorSafetyHelpers that kill motors if you don't command them often enough? What about the Watchdog?

What's so important that you want to risk damaging people and property by driving a robot you can't see or stop effectively? The things are dangerous enough when you're watching them from 5 feet away.
Our robot only runs after hours and this would be on the schools track, not inside, but the track has multiple wifi repeaters. I'm looking at severe circumstances to train autonomous and refine it. It will eventually be able to navigate through a mapped out model of the real world (this is for off season, but the networking would be cool to set up now).

Re: Connect to RoboRIO from Internet

I actually tried this last year at my school. I was able to setup the radio to bridge my school's wifi connection, and then connect to the robot over the school's wifi network. It seemed like a great idea for training for drive by wire, but I discovered that as the robot drove down the hallway, it had to switched between different access points. Each time it switched access points, I lost driver station comms for just a second, and it proved to be unusable.

The robot radio should be more than capable of handling the distance. You shouldn't need to use the School's wifi.

Re: Connect to RoboRIO from Internet

The robot communicates over Ethernet. All is simple as long as you are on the same LAN & same subnet. The robot typically uses non-routable IP addresses. Which means they don't go through the router. If the drive station is on the other side of the router as it would be if you are using the internet or some building Ethernet typologies. You would need a VPN or other Ethernet voodoo for it to work
