I'm tempted to say they're from the mid 20th century, but I can't say for certain.
1. The first is about robot explorers sent from a robot society to the solar system. They found it based on an old star system map that came from the beginning of their society, which their recent advances allowed them to pin-point as our solar system. I believe there were three of them. They are equipped with anti-gravity devices and could communicate with radio. However, each is equipped with sound communication, and one of them wonders why all robots have them when radio is much more efficient. They arrive in the solar system to find ruins. There were no humans, but there were animals, and the robots discussion machine evolution v. biological evolution. I believe they stopped at a Martian colony, but I can't say for certain. The story ends with one of the robots finding a statue of a human that has fallen. It re-erects the statue and voices a bit of sentiment about how humans shared the robots' dreams of sentience.
2. The second is a prequel to the first story. It was written by a different author with permission from the first author. It explores how the human society ended, and how the robot society started. Humanity was largely wiped out by a deadly virus that quickly destroyed the population of Earth. The story follows a spaceship with a few humans. They escaped to Mars and found that it had the same virus. Then they went into deep space. Most of the humans were put into cryosleep, and a few sentient robots were set with the task of finding a cure. They tried a lot of different cures, but none worked before the humans slowly died. The last few humans decided to land on a deserted planet and leave the robots to form a new society. The humans erased the robots' memories so they wouldn't be burdened with the past, but they left a map of the solar system with the robots so that one day they might find it. The story ends with one of the humans thinking about how humanity's dream would continue with the robots as he goes into space to die.
3. This one is unrelated to the first two. It's about a robot society that knew it used to be servants made by humans. Humans died out for some reason. Some robot scientists are now trying to make new humans to learn about instincts. During the robots' discussion of instincts, one explicitly mentions Asimov, though spelled as "Asenion." It ends with the reveal that the robot's instinct is to kneel and obey the humans they made.
I would be grateful if someone could tell me what these stories are or point me to a database where I can find the titles in a more restricted search than Google.
