RB-series nursemaid robot: behavior firmware

U.S. Robots and Mechanical Men, 1996. Firmware for household robots.

Description

Behavior firmware from one of the first household robots sold to look after children.

The RB series could not speak. It communicated by gesture, played simple games and was designed above all to keep a child safe. Its firmware includes a library of stories it could be asked to have read aloud to it.

Provenance

Read from a unit retired by the Weston family after twenty-two years in their household, and released for access by its manufacturer.

The family asked that the robot’s story library be kept. Its logs show one story was requested several thousand times.
