Pearl The Nursebot

"NurseBot is an autonomous mobile robot that 'lives' in a private home of a chronically ill elderly person. The robot provides a research platform to test out a range of ideas for assisting elderly people, such as: What would you like to have a robot help out with around the house? . . .Some observers noted that having a more expressive countenance seems to be an advantage, but if the robot becomes 'too humanlike, it can creep people out.'
The question of 'how human should a robot look' has great implications on how effective and accepted robotic assistants can be.' (via)
