  • Pearl is a nurse robot developed by the University of Pittsburgh and the Carnegie Mellon University in order to help the elderly. It is part of the project called Personal Robotic Assistants for the Elderly, which they started several years ago.

    The project was aimed to create a mobile, personal service robot that assists and helps people especially the elderly, who suffer from chronic disorders, to go about their daily routines. The Pearl can remind the elderly about their hygiene, physicians’ visits, and other vital information that they also remotely send to human caregivers and health providers. Pearl can also act as a companion, especially to patients who are living alone, as this robot is also socially active.

    With the growing number of the aging population, the developers of Pearl are continuously researching on how to improve this nurse robot further. Their aim is to make it a state-of-the-art mobile service using advanced human-robot interaction.
