Camera on robot with monitor on controls.

[Bongle]

I think this would be legal if:
-you had a camera powered by the robot, connected to the RC just like any other sensor
-the data was compressed on the RC and sent to the OI over the radio modem

This way, it would be no different from any other sensor that outputs data to the operator interface.

The main problem is that it is pretty much impossible to send high-fidelity real-time video over the modem connection between robot and operator interface because of the lack of bandwidth. Compression would be difficult on the RC because you wouldn't have much computing power. You could have a coprocessor to compress and have the RC send the compressed data back over the modem, but you're still going to end up with a terrible image at the driver's end. Take a video and compress it to 64kbps with a modern codec like xvid or h.264. That's the kind of quality you'd be getting if you want real-time feedback.
