AI and Robotics

Robots can do what humans can, but not everything. I am certain that a robot won't be able to do most things of what a human can do. Us humans aren't perfect and so will be the robots. If we were to program a robot there is a chance that the robot will end up having a bug which will cause errors. Who is to be blame if the robots ends up causing trouble? In the article "Should we put robots on trial?" stated who is to be blame if you were to be injured by a machine that moves by itself? I will think that the companies that created that machine will be the ones to face the consequences. I think it will be a long time from now that we will be able to see robots walking and living with humans.
