I was visiting the Arizona Science Center this weekend with my kids (great place, BTW). Just outside the building there was a big Bomb Squad van and they were demonstraiting two of their robots. Here's a picture of one of them with my 6 year old son next to it. They let him drive it around using its remote control.
Unfortunately I didn't have my camera with me so I didn't get a shot of the other one or any video, which would have been sweet. At least my cell phone allowed me to get this one shot.
