Without making people too nuts over ITAR, even though its a de-mining robot, think more something like this, but with rubber/composite diggers/grabbers www.vernoncomputersource.com/sites/default/files/images/Erins/cool diggerbot.jpg

And only about 80ish kilos, as they are by nature expandable, and are made to blow up, be blown up by de-mining charges inside the ball hopper/inverted blast cone thing.

vs the classic ball bot.

That's probably enough to get a few people screaming OPSEC OPSEC! The Sky is Falling! The Chinamen will copy out designs and sell then CHEAPER to third world nations! All is ANARCHY! We're doomed! Doomed!

Forgetting of course, that the de-mining robots are going to be used in conflict, and former conflict zones, and likely, gutted for parts, and thrown on a pile when done. Making reverse engineering kind of easy anyway. ;P

Probably less hassle to use some larval engineers ball bots. ;)

Might be they were hauling something a bit more sensitive than usual. Or it could have been one of numerous scares related to terrorist plots. However, lots of these so called plots were just BS made up to cause chaos stateside.

I dunno, if they painted and textured the dachshunds grass green, they'd have the perfect unobtrusive, yet sorta fast, ball recovery system

I did design sort of a de-mining robot. I suppose that could be used to scoop up the balls. Although, something designed to hold in the blast of 6-8 cluster bombs might not be 100% safe to be zipping around people, running on grass, or low density baked clay surfaces.

Think of a sort of cross between a battle bot, and a very all terrain roomba. :D
