A friend of mine sent a few articles about Military Robotics Research.
The titles’ definitely grab your attention,
Upcoming Military Robot Could Feed on Dead Bodies
Powerful Ideas: Military Develops ‘Cybug’ Spies
insert zombie or cyborg joke below …
This is bad comedy.
While the idea of the robot “feeding on dead bodies” makes a nice headline for Fox news, the concept of having an herbivorous robot makes a lot of sense… I mean… why couldn’t a robot lawnmower power itself using lawn trimmings? Or, I suppose… I could just get a couple sheep and implant that cybug technology into them!

Do electric sheep dream of androids?
I could use some help with dust down here. Powered by dust or hey, a vacuum cleaner powered by the stuff it sucks up… which includes - dust -
I’m not a dust person.
If you could make it run on pollen and cat hair while you are at it, it would be greatly appreciated.
There might be a market for a robot that eats kudzu. It would need to have a fairly long service life, though – many states in the southern tier of the US are covered with the stuff, so a kudzu-bot might need to run continuously for several years, eating at least a ton per day, to keep up with the growth rate. 
All of our robots that are more than 2 years old do a great job collecting dust. It is a bit bizarre. There were no special modifications required other than they be left alone for a couple months at a time. Best part is the dust is on the surface, so you can see what a great job they are doing at collecting all that extra dust.
the “engine” used in the first one is interesting, i kind of reminds me of Mr.Fusion :]

I just read about this. Apparently, the part about eating dead bodies was added in by Fox News.
