Easy to use, simply sit I-Dog Interactive Music Companion in front of a speaker or plug it into the headphone jack of any hand-held music system and I-Dog will move and groove to the rhythm of the song. I-Dog displays four distinct personalities that are dependent on the type of music it hears: rock and punk make it rebellious, classical and country relax the I-Dog, pop and R&B make the robot happy and dance music excites him. In addition to head and ear movement, I-Dog expresses its different personalities through a unique array of colorful LEDs located on its face.
