The Art of Defense Machines, Today in Washington, DCS

Today the federal government of the US will be spending roughly $50 million on state-of-the-art defense during today's inauguration of President Barack Obama. Here, a robot bomb sniffer gets ready for the big day.

New Scientist has a nice gallery up featuring some of the machines the F.B.I. is deploying to Washington, D.C. According to Subtopia's Bryan Finoki, "DC officials fessed to dolling out roughly $50m, while Maryland and Virginia both have pitched in another $12-16m each."

While the robot waits patiently above, another bomb squad vehicle carries this explosion containment device. Stick the bomb inside, and hopefully it will go off without doing as much damage. Check out more mobile defense labs in this gallery.
