Although other countries have deployed gun-toting robots and there's no shortage of companies trying to develop weaponized bots for Uncle Sam, it looks like the first test of actual killer robots in battle has ended in a whimper: the Army's TALON SWORD gunbots, are headed home, after being plagued with control issues. Yeah, that's right -- control issues. Apparently it was too hard to prevent the Army's gun-equipped robot from moving its gun "when it was not intended to move." Reassuring, no? The Army doesn't sound too enthused about another go-round, saying, "once you've done something that's really bad, it can take 10 or 20 years to try it again." Ouch. On the plus side, at least that's 20 more years before we're all put to work in the mines, no?
