A SCARY SIGHT TO SEE: Yoichi Takamoto, proud father of the robot guard dragon By TOSHIYUKI OTAKI, The Asahi Shimbun
When its infrared sensors detect someone approaching, it stands alert and menacing with its eyes flashing blue. The robot Banryu, or ``guard dragon,'' is 90 centimeters tall, weighs 35 kilograms and is actually quite scary.
With more than 50 built-in sensors, Banryu is capable of picking up changes in its surroundings and transmitting an alarm to its master's cellphone.
A camera on its back can swivel 360 degrees and send images of the room around it. It can also sense the smell of burning and detect temperatures above 50 degrees.
