The spreading device and the spreading manner null which use the radi-con helicopter

摘要

PROBLEM TO BE SOLVED: To provide a spraying apparatus using a radio controlled helicopter for spraying a liquid agent or a granular agent in an amount depending on a flight velocity even to a place difficult to be seen by and remote from an operator.;SOLUTION: The spraying apparatus comprises a tank for holding the liquid agent or the granular agent, a spraying mechanism for spraying the liquid agent or the granular agent, a sensor for detecting wind power, a controlling unit for controlling the spraying mechanism and an electric power source for supplying electric power to the spraying mechanism. The amount to be sprayed from the spraying mechanism is controlled depending on an output signal from the sensor. Therefore, the liquid agent or the granular agent is sprayed depending on the flight velocity even in the place hardly visible and remote from the operator.;COPYRIGHT: (C)2005,JPO&NCIPI
