Roboraptor

Roboraptor is a robotic dinosaur from WowWee Robotics Inc.

Autonomous behaviors
It has four different modes of behavior or moods: hunting, cautious, playful, and free-roam. In hunting mode, it will react to sharp sounds and progressively focus its attention more intensely on repeated sounds coming from the same direction. In cautious mode, it will react oppositely and move away from sounds it hears. In playful mode, it will react to sounds in a more whimsical fashion but neither approaching nor avoiding them. In free-roam mode, it will explore its environment, avoiding obstacles and stopping occasionally to listen for loud sounds to investigate. The Raptor does not walk well on carpet and cannot be programmed.
