The Robots of Dawn

Earth detective summoned to the Spacer world of Aurora to investigate the mental destruction of a humaniform robot, while wrestling with his own deep-seated agoraphobia.

Baley's humaniform robot partner from Earth, created by Han Fastolfe and identical in appearance to the robot whose mind was destroyed.

Auroran roboticist who created Daneel and the destroyed robot Jander, and is the only person believed capable of the crime, though he denies committing it.

An earlier-model robot serving as Fastolfe's household aide on Aurora, quieter and less humanlike than Daneel but present throughout the investigation.

Han Fastolfe's estranged daughter and a roboticist in her own right, whose past work with his robots draws her into the investigation on Aurora.
