Management ship and working robots in waters based on wireless network and working robot control method thereof
First Claim
1. A robot-ship group for executing a work operation on sea and river, the robot-ship group comprising:
- at least one working robot;
a first mother ship having the at least one working robot; and
a second mother ship whose communication region is overlapped with a communication region of the first mother ship,wherein the at least one working robot includes;
a signal strength measurement means for measuring strength of pre-defined signals transmitted from the first mother ship and the second mother ship; and
a working robot control means for determining which of the first mother ship and the second mother ship the at least one working robot is to communicate with according to a comparison result of the signal strength measured in the signal strength measurement means, and controlling the at least one working robot to perform the work according to a set-up route, andwherein the first mother ship includes;
a working robot preparing unit for performing a preparation work required before and after the at least one working robot performs the work; and
a mother ship control unit for transmitting a pre-defined signal to the at least one working robot after said performing by the working robot preparing unit,wherein the working robot control means calculates an average value of the signal strength measured by the signal strength measurement means at a predetermined time and determines which of the first mother ship and the second mother ship the at least one working robot is to communicate with.

Abstract
Provided are a management ship and working robots in waters based on a wireless network and a method for controlling working robots thereof. The robot-ship group includes: a signal strength measuring unit for measuring strengths of pre-defined signals; and a working robot control unit for determining which of the first mother ship and the second mother ship the working robot is to communicate with according to a comparison result of the signal strength, and controlling the working robots to perform the work according to a set-up route, wherein the first mother ship includes: a working robot preparing unit for performing a preparation work required before and after the working robots perform the work; and a mother ship control unit for transmitting the pre-defined signal to the working robot and communicating data with the working robot.

8. A method for controlling working robots for a work on sea and river through a wireless network formed by a first mother ship having at least one working robot for work on the sea or river and a wireless network formed by a second mother ship whose communication region is overlapped with the communication region of the first mother ship, the method comprising the steps of:
-
a) measuring strength of pre-defined signals transmitted from the first mother ship and the second mother ship; b) comparing strength of the signals measured in the step a), and determining which of the first mother ship and the second mother ship the working robot is to communicate with; and c) performing data communication with the determined mother ship and performing a work according to a set-up route, wherein the step c) includes the steps of; c1) when the working robot is determined to communicate data with the second mother ship, requesting the first mother ship for information needed to communicate with the second mother ship; c2) when the requested information is received from the first mother ship, notifying movement into the communication region of the second mother ship to the first mother ship and requesting the second mother ship for a temporary communication address; and c3) ending communication with the first mother ship upon the receipt of the temporary communication address and communicating with the second mother ship based on the temporary communication address. - View Dependent Claims (9, 10)
