Since high school days, I have imagined someday we would all have a personal assistant robot (PAR) as an EDC of sorts. Rather, such a device would tag along beside us and provide certain functions as well as securely stow our necessaries. It could serve as a sentry/security system, carry provisions, supplies, and materials, keep us all interconnected, retain all our personal information digitally, and so on. It could either roll, walk, or fly depending on terrain and conditions.

Maybe not in my lifetime now, but doable I think within the next 50 years or so.

Tom Selleck and Gene Simmons were in a movie called "Runaways", that had basic elements of my idea. While I thought up the notion long before the movie came out, I'm not sure mine was an original thought. Most likely, it was something Jules Verne wrote about somewhere.
