The robot Pearl is a typical prototype of the nursebot project. Pearl deals with old men and old women. Her job is mainly about reminding her clients to eat, drink, take medicine or use the bathroom, she also guides the old folks from room to room as she chats about the weather or TV listings. Pearl is a self-directed mobile robot with an advanced artificial intelligence to assist people with the activities of daily living. This summer, this 4-and-a-half-foot-tall robot nurse is underway her field testing at Longwood Retirement Community in Oakmont, Pa., and She has won the hearts of elderly folks there. “We’re getting along beautifully,” says one older gentleman as Pearl leads him to a room for his therapy session at Longwood. “But, I won’t say whether she’s my kind of girl,” he quips.
Pearl manage to perform some simple face expression, tough still a little bit funny. Pearl's designers say that they took special care to make Pearl prettier, but it's what's inside Pearl counts: Two Intel® Pentium® 4 processor-based PCs run software to endow her with wit and ability to navigate; a differential drive system propels her; Wi-Fi helps her communicate as she rolls along; laser range finders, stereo camera systems, and sonar sensors guide her around obstructions; microphones help her recognize words; speakers enable others to hear her synthesized speech; an actuated head unit swivels in lifelike animation. All this and more is housed in her slender frame.
