He tied them together in the end, so they're in the same universe, just many millennia apart. I wish we'd gotten to find out where he planned to take things after the final Foundation novel chronologically. He'd created an interesting setup. Since there's some spoilers involved:

Spoiler:

The Solarians that had vanished in the final Robot novels turned out to have deliberately evolved themselves to the point they were an alien species compared to regular humanity. At the end Trevize chooses to allow Daneel to continue guiding the development of humanity into Galaxia, because of the possibility of advanced alien life from beyond the galaxy attacking humanity. It then hints that the Solarians may be/become that threat.

Asimov was more interested in story over character development, which is why many of his characters don't have a lot of personality. I don't think the robots had more personality than the human characters (or at least not more than Elijah Bailey, the main character of the first three), but it felt that way because we didn't expect robots to have personalities at all. We remember their personalities better because of that.
