Robonanny is a proposed robot that can perform the duties of a nanny by caring for babies and children, including feeding, changing diapers, helping with walking/talking, entertaining, and assisting with homework. It aims to help modern families where both parents work and need assistance. While challenging to develop a robot with an acceptable appearance and the needed knowledge/affection, proponents believe it could successfully care for various aspects of children's lives and allow parents more control over childcare costs and quality.
