The questions regarding the radios and database choice are still open. Regarding the radios, I can just try both and see which one works better. It is a little harder to do that with the database question...

Next step is to order a couple of radios, and start architecting the server-side portion. After that, I can design UI flows, and put together all the pieces. Once I have basic sensor logging and searching done, I can add the video feed, and video processing to identify movement.

For now, rovers are going to be the main focus. I'll add in tweaking for other robot types later.
