The beast measures in at 65 centimeters (2.2 feet) in length, which is about the same size as an actual wolf. It also has tufts of gangly hair and an impressive set of white fangs. It uses solar-rechargeable batteries to sustain itself, and it detects intruders with its infrared ray sensor.
According to the BBC, once the robot wolf senses a creature nearby, it uses a wide range of sounds, including a gunshot, a howl, and a human voice, to frighten away the would-be diner.  Of course, any humans who are unfortunate enough to stumble into the vicinity are also likely frightened away by claps of gunshots, but I suppose that is the price we must pay for modern conveniences.
