Robots v Humans?

While reading Caves of Steel, it got me thinking about robots and how they compare to humans. I wanted to bring up a possible discussion question, do we think that this novel is trying to touch on the idea that robots are superior to humans? Do we think that it is trying to prove this or at least explore this idea through Daneel and R Sammy? They are different and have different abilities that can be compared, but they are definitely not your average "human" per say.

Here is a picture of some of the robots I thought of in my head while reading :)
