How is the robot able to all the things it has to when it's servicing a mission? (unscrewing different sized caps, snipping wires, etc.)

1. How does the robot 'see' to reach out and grab a satellite to service it? Is there a camera with someone on Earth (or the Space Station watching it?) Does the robot use lasers? (It should be lasers, lasers are cool...)
2. Do you take the robot servicing arm to the satellites, or would the satellites come to the robot arm?
3. Is it true that there's a building in Maryland full of nothing but robotic arms? (Pics or it doesn't exist...(grin))

Is it possible for liquid ethanol (or hydrazine for that matter) to explode? (Or wouldn't it explode because of the lack of oxygen in space?)
