What are your rights if you are attacked by one of these robots (like the child mentioned at the end of this article)? If you disable the robot in self-defense, is that considered vandalism?

The child was playing with the robot and got knocked over while messing with it. There was no attack, just an unattended child and a mom dodging her responsibility by blaming others and trying to get paid.
I think you have bigger issues to worry about even if you don't think you do.
You are currently very safe and not in danger of robot attacks, but if actually attacked, I'm pretty sure you can legally protect yourself
You can disable a car if it attacks you as well, or any other machine. Not sure about zombies though.

"The robot was not seriously damaged."

Can these robots talk? I can imagine now, the robot saying things like "It's just a flesh wound! I'm invincible! None shall pass! 'Tis but a scratch!"

Even though it's unarmed, at 300 pounds it could probably do a pretty intimidating bull-rush at someone.

Its about as intimidating as the robots that deliver medications in hospitals. Maybe a bit faster, but I wouldn't use the term "Rush" ;)

Funny that this article portrays the robot as a person. Words like "assault" and "scuffle" shouldn't play a part in this, but it's only a matter of time.

p.s. what a lousy security guard

Security robot knocked over by a drunk? I would reconsider any investment in that company...

Jason Sylvain is a hero ; kill robots ; kill robots.

Seriously, this is utterly stupid to charge a drunk guy for that... because every Friday night on Castro street, then they would be no one left.

Viva Jason Sylvain! I don't know him but at least he din't turn himself into an idiot / moron talking about "security" especially when snooping smartphones data... hence privacy. Those guys are dangerous peeping toms ; pervs.

Laugh about robots all you like. But they could double as drones and kill at (someone's) will. Heck, after the machines finish taking over, they may even send one of their own back in time to kill the mother of a leader of the dwidling human resistance. And that robot could - at another time -
become Governor of California. Okay, now I am just being silly. A terminator as governor? Preposterous.

that is exactly why we should give everyone a lifetime supply of free alcohol. but i should get moer than the others because it was my idea

Can a robot be programmed to make a citizen's arrest. Or does it have to become naturalized first?
