Meet Zora, the Robot Caregiver

It may not look like much -- more cute toy than futuristic marvel -- but this robot is at the center of an experiment in France to change care for elderly patients. When Zora arrived at this nursing facility an hour outside Paris, a strange thing began happening: Many patients developed an emotional attachment, treating it like a baby, holding and cooing, giving it kisses on the head. Zora, which can cost up to $18,000, offered companionship in a place where life can be lonely. Families can visit only so much, and staff members are stretched. Patients at the hospital, called Jouarre, have dementia and other conditions that require round-the-clock care.
