CHO (Japanese for butterfly) is a flying object for finding people buried under rubble. Its standard features include infrared sensors, a rechargeable battery and a camera. When the camera is pointed in a horizontal direction, it serves as a navigation aid. When it it is rotated to face downwards, it provides a mapping function. A plug-in microwave radar module with an integrated transmitter and receiver locates people buried under rubble. Because its rotors are arranged in pairs, CHO can be knocked down to a compact size for transport and storage. The housing, rotor hinges, -blades and -connectors are made of light and durable plastic
