Runs on Gas,,
I see limited use, limited fuel, noise (engine&feet), limited user interface..
BUT, it's a hell of a Pack-Bot demonstrator. I first watch the videos last year, the demo was much more vigorous,, it showed someone kicking the snot out of the Bot and it did a very good job of staying up-right.
Technology wise I give it a 7.5-8.5, but it's still to young for field use..
Now here is an older technology that has many advantages:
- stealth
- fuel readily available world wide
- low maintenance
- can be converted to a rudimentary food supplement
