I know I've been going off on a "robots are gonna kill us all" tirade lately, but quite frankly, that's because they are. So I'll just offer this last piece of evidence and let it rest for awhile. Introducing the forest fire prevention robot by Jordan Guelde (that sick, robot sympathizing bastard). The unit was designed to go in and remove (read: cut the everliving hell out of by way of giant spinning blades) trees surrounding a forest fire so it can't spread. To me it looks like it was designed to kill every last human being on the face of the planet. But what do I know? I only have a doctorate in robotic technology from the University of Outer Damn Space. And no, you can't see my diploma -- it's holographic, you'd probably try to steal it.
A ton more pictures of the killing machine after the jump. Oh, and by the way, the robot was actually designed for entertainment, so we might actually be safer than I initially made it seem. Psyche! We're effed.

Thanks to Leigh and Shawn, both of whom would make great additions to my elite force of robot ass-kickers, for the tips
