One way I think that "robots" will change in the future is medically. Robotic surgery is a reality now but I believe that in the future it will become much more common and a lot more advanced. There are many advantages related to this kind of robotic technology such as quicker healing time , it is less invasive, not as much blood loss, etc.
I do not think there is any possibility of robots becoming autonomous. I think they may develop some form of intelligence but not nearly enough to make them "human." I do not think that robots will take over the world like seen in many science fiction films. I think in the future they will just make our lives easier.
