What is the name of the humanoid robot detective in Isaac Asimov's Robot series? The answer is R. Daneel Olivaw.

Daneel first appears in The Caves of Steel, where he is paired with human police detective Elijah Baley to investigate a murder in a future Earth city. The “R.” stands for “Robot,” following a naming convention in Asimov’s fictional society.

Daneel is a humaniform robot: he looks and behaves so much like a person that he can work undercover among humans. His positronic brain is governed by Asimov’s Three Laws of Robotics, and he possesses the advanced ability of cerebroanalysis, which interprets clues from human brain activity.

Readers sometimes confuse Daneel with R. Giskard Reventlov, another important robot in the series. Giskard is a distinct character who later transfers his mental abilities to Daneel. Daneel also becomes a bridge between the Robot and Foundation stories, surviving for thousands of years under changing identities.
