Re: The communication tides are shifting...

Question:

- Are all robots Crios and Cameras operating on a single common Wifi Channel ? I believe so. When there are a number of non-overlapping wifi channels available, why would we not make use of them (bit more configuration hassle). Put the camera streams on one channel and data on another. Or 2 robots out of 6 on each channel. Yes the field would need 3 radios I believe.
- also, at a competition where 4 fields x 6 robots are all on the same channel and close enough to each other the RF collision and retry rate must be enormous.

re the comment about the CRIO's being bullet proof. I don't disagree but there is still (always) room for improvement. I have seen a number of glitches and failures where better diagnostics and reporting would greatly help: CRios rebooting randomly, cause unknown, chips blown off their PCBs in the I/O cards. A number of dead $150++ I/O cards.

Also it would be so productive if the CRIo could reboot and reconnect in a second or two. It is a realtime system.
