Sega's idog -- The Friendly Robot Puppy

Both the idog and iPod can play together on your desk without messy clean-up.

Sega unleashed its newest creation in Tokyo; a robotic dog called idog that can compose, play and dance to music.

Owners can program idog with an audio input jack at the base of its left hind leg (it's friendly with Apple's iPod, for instance). It has room for about 70 children's songs.

The idog has a number of switches located on its nose and other parts of its body that can cause the robot dog react to movement and to light up. The idog can express its emotions by moving its head and ears. It will cost about $40 and will be introduced in Japan in April.

How much is that doggy in the window? Forty bucks? Steal!

A famous science-fictional robot dog that can also sense movement and express emotion is Ray Bradbury's Mechanical Hound from his 1953 masterpiece Fahrenheit 451:

Montag touched the muzzle.The Hound growled.Montag jumped back.The Hound half rose in its kennel and looked at him with green-blue neon light flickering in its suddenly activated eyebulbs. It growled again, a strange rasping combination of electrical sizzle, a frying sound, a scraping of metal, a turning of cogs that seemed rusty and ancient with suspicion."No, no, boy," said Montag, his heart pounding.He saw the silver needle extended upon the air an inch, pull back, extend, pull back.The growl simmered in the beast and it looked at him. Montag backed up. The Hound took a step from its kennel.Montag grabbed the brass pole with one hand. The pole, reacting, slid upward, and took him through the ceiling, quietly. He stepped off in the half-lit deck of the upper level. He was trembling and his face was green-white. Below, the Hound had sunk back down upon its eight incredible insect legs and was humming to itself again, its multi-faceted eyes at peace.(Read more about Bradbury's Mechanical Hound.)

Hopefully, the cute, puppy-like idog will be friendlier than the Hound. The Hound was the companion of the firemen, who burned books instead of putting out fires. It also hunted enemies of the state by smell.
