REMOTELY STEERABLE UNMANNED BOAT, AND REMOTE CONTROL DEVICE

Japanese Patent JP3939710

B2

PROBLEM TO BE SOLVED: To provide a remotely steerable unmanned boat to be surely collected without being lost.
SOLUTION: The remotely steerable unmanned boat comprises a propulsion power source 11 to generate the propulsion power, a steering device 13 capable of freely changing the advancing direction, a first transmission/reception antenna 14 to receive the signal which is transmitted by radio from a steering device 20, a first control device 15 to control the propulsion power source 11 and the steering device 13 based on the signal received by the first transmission-reception antenna 14, a storage device 17 to store the preset initial position and a GPS antenna 16 to receive the radio wave transmitted from an artificial satellite. The first control device calculates the present position based on the radio wave received by the GPS antenna 16, and starts the automatic control of the propulsion power source 11 and the steering device 13 so as to be returned to the initial position based on the present position and the initial position when a predetermined condition is satisfied.
