Armed Robots?

The US army uses the first tactical robots in Iraq – moving the war to a new technological level. Those little beasts seem pretty efficient (see video). But being in the Army and coming from an information security background, I’m wondering how the data-transmission works. I think it would be fun to hijack those thingies on a battlefield. And even if they are not easily hijackable (what I hope for the US troops), who prevents the bad guys from jamming the whole battlefield with strong signals? I could build a wireless jammer in a week … this would render their iron friends pretty useless. As a starting point for the bad guys, the manufacturer pus the datasheets online :-) . I’m getting a 404 when I try to download one though ;-) . They’ll need supercomputers on the battlefields soon … ah, my job is secured forever!
