Group robot and location control method of group robot

PURPOSE: A swarm robot and a location control method therefor are provided to minimize the load and structure of a system by minimizing the structure of multiple slave robots. CONSTITUTION: A swarm robot is composed of a master robot(MR) and multiple slave robots(SR1,SR2,SR3,SR4,SR5,SR6,SR7,SR8). The master robot comprises a current position detection module, first and second RF nodes, an upper plate rotating motor, an upper plate rotating unit, and a control module. The first and second RF nodes detect distances from the slave robots to the RF nodes. The control module receives the distance information from the first and second nodes and controls the upper plate rotating motor and unit. And the control module calculates the positions of the slave robots based on the current position. The slave robots are installed on the center of an upper plate. RF nodes of the slave robots communicate with the first and second RF nodes of the master robot.
