MOBILE ROBOT LOCATION METHOD

摘要

A mobile robot location method is provided to locate the position of a mobile robot accurately by using MUSIC(Multiple Signal Classification) algorithm. A mobile robot location method comprises a step of transmitting a location request signal to a mobile robot through a first antenna(111), a step of receiving response signals transmitted in response to the location request signal through the first antenna and a second antenna composed of array antennas(113a,113b,113c), a step of estimating the distance to the mobile robot based on the response signal received through the first antenna, and a step of predicting the direction of the mobile robot based on the response signal received through the second antenna.
