A Hello Kitty robot for baby sitting is available for pre-order at a not so affordable $6,299.99.

NEC and Futaba Industrial Co., Ltd started to work on the Hello Kitty Robo back in 2004.

The Hello Kitty Robo features face recognition via stereo CMOS cameras, voice recognition, ultrasonic sensor, lift-up sensor and AV connector.
The 52cm tall Hello Kitty can chat with you in three different situations: 1 As a close friend; 2 With the family; 3 Guessing game.
The head and arms move. The accessories include a Mouse, not sure what you can do with that. Possibly the Kitty Robo is also a gaming computer.
