Remote control unmanned boat and remote control device
First Claim
1. A remote control unmanned boat comprising:
- a propelling power source for generating a propelling power,a steering device for freely varying the direction of travel,a first transmit-receive antenna for receiving a signal transmitted by radio by a remote control device,a first controller for controlling said propelling power source and said steering device based on said signal received by said first transmit-receive antenna,a memory device for memorizing an initial position set in advance,a GPS antenna for receiving an electric wave transmitted from an artificial satellite,said first controller being adapted to calculate the present position based on the electric wave received by said GPS antenna and, when stated conditions are satisfied said first transmit-receive antenna becomes temporarily disabled so that it becomes temporarily incapable of receiving said signal, to initiate automatic control of said propelling power source and said steering device so as to be regressed to the initial position based on said present position and said initial position, andsaid first controller, when said first transmit-receive antenna becomes capable of receiving said received signal during said automatic control, terminates said automatic control and resumes control based on the signal from said remote control device,a surveying device for surveying the states of water body and water bottom, wherein said first transmit-receive antenna causes information obtained from the survey concerning the states of water body and water bottom surveyed by said surveying device to be transmitted by a specific electric wave to said remote control steering device,a second transmit-receive antenna for transmitting by radio the signal concerning the operations of said propelling power source and said steering device to said remote control unmanned boat and receiving the information obtained from the survey concerning the states of water body and water bottom surveyed by said surveying device, anda second controller for feeding the signals of operations concerning said propelling power source, said steering device, and said surveying device to said second transmit-receive antenna.

Abstract
This invention concerns a remote control unmanned boat which can be freely operated by remote control and a remote control device. The remote control unmanned boat comprises a propelling power source 11 for generating a propelling power, a steering device 13 for freely varying the direction of advance, a first transmit-receive antenna 24 for receiving the signal transmitted by ratio from a control device 20, a first controller 15 for controlling the propelling power source 11 and the steering device 13 based on the signal received from the first transmit-receive antenna 14, a memory device 17 for memorizing the initial position set in advance, and a GPS antenna 16 for receiving the electric wave transmitted from an artificial satellite. The first controller 15 calculates the present position based on the electric wave received by the GPS antenna 16 and, when the stated condition is satisfied, initiates automatic control of the propelling power source 11 and the steering device 13 so as to attain regression to the initial position based on the present position and the initial position. Thus, the remote control unmanned boat has no possibility of being missed.
