PaPeRo – Personal Robot in development by NEC
PaPeRo stands for ‘Partner type Personal Robot’. When it has nothing to do, PaPeRo will wander around the room, using visual and ultrasonic sensors, for fun or to look for someone. When PaPeRo finds a person, it will try to communicate with the person. Its behavior and reaction to you will change according to your behavior towards the robot.

“NEC has been revising this robot since 1997 and they think that now they have gotten it right. Personal Robot PaPeRo 2003 is over a foot tall and can do some amazing things like recognize faces, listen for phrases and respond verbally, change the channel on the TV for you, check email for you, a lot of other stuff too numerous to mention. It has two cameras for eyes for face recognition so it can call you by name. It has four microphones for voice and command recognition. It has 5 ultrasonic sensors to help it navigate. TV output, a wireless internet connection, LEDs for facial expressions, it even has a stroking sensor so it can feel you stroking it’s head.” ~ Robots.net
