Randy Weaver's (the white supremacist in Idaho at the Ruby Ridge standoff)wife was killed by a remotely piloted bomb disposal robot at thier front door. I think that was the first time that something like that had happened, even tho in this case the robot was under human control.
This is more of a safety on the job issue:

There are also many developing projects for near autonomic function machines expressly built for war. Things like the Predator, The US Arsenal Stealth Warship, et al., were concieved as totally automatic weapon systems at the outset.
India has shown serious interest in developing "Warbots" over the last couple of years.
Technical advancement is only as destructive as the people who use it, and that goes for any kind of robot. An industrial robot at this stage does not really know if its welding a car body or drilling holes in someone's head. There's no evil intent , just programming.
I find it highly dubious that even a highly advanced (and let's assume self-aware) robot would ever suddenly go on a killing spree, waving its arms and saying "kill all humans". People can barely get computers to behave properly without substantial programming, so I doubt anyone would be truly dumb enough to build an ED-209 or a Terminator and make it totally autonomous.
The three laws of robotics were a brilliant plot device in all of Asimov's novels, but I have a hard time buying them ever being needed in the real world. He was definitely writing for a different time back then. Some of the applications of the laws seem almost magical. So wide open to interpretation of the complexity that robopsycologists are needed.
Aside from the military applications of robotics (which I am NOT in favor of, as in the long run it would make warfare about as consequential as playing an X-Box) robots ultimately will be made to SERVE people by thier very design. That's the idea at its core. Only my cats fear the Roomba we have working on our rug. I sleep easy at night knowing that it is not going to suddenly freak out and shoot sawblades at me. I for one am more than glad to not have to vacuum floors anymore. That's robot work.
