Onboard Live Feeds from Robots?

OK, time for some broadcast input...
Many of the cameras that would be cheap enough for wide use will not have great resolution or great lenses. They will have fixed focal lengths, i.e. a permanent field of view. The cameras in use in Nascar are specific designs with special transmitters and are set up by professionals before the race. Many fail during the race for a variety of reasons. Remember that racecars have rubber tires and suspension (albeit stiff for better control), robots do not, so the vibration and g-forces encountered on our robots are significant. Transmitters in the TV bands that are below a certain power do not need licenses but must prevent interference with local services. These transmitters will be marked in the catalog as needing FCC approval or license. There are many cheap 2.4 GHz analog video transmitters that would be suitable for the short distances on the field and operate in experimental bands that do not require a license. Those teams that are considering using a camera should view the video from teams that have already tried this approach to see if a camera would be suitable for your use before investing in the equipment.
Above all, camera systems need to be inspected by robot inspectors to insure safety for the field and personnel as well as correct use of electrical power systems and wiring.
