Looking, frankly, malevolent at your taste in music, Tiger Electronics’ A.M.P. Automated Music Personality robot is meant to “revolutionize how and where you listen to music.” Standing 29-inches high, the A.M.P. uses a piezoelectric gyroscope to stay upright on his twin-wheels (with a flip-out kick-stand for stationary use) and lets you plug in any MP3 player, stow it in his back compartment, and then watch in astonished horror as it “dances” to the music’s beat, flashing its 49 LEDs and adding any of more than 62 sound effects. Playback is via the built-in 12 watt amp, through a 5-inch mid-range speaker and two high output tweeters. On the A.M.P.’s hands are touch-sensitive mixing pads, the left controlling music effects and the right controlling the audio itself.
