METHOD AND DEVICE FOR RECOGNIZING THE LOCATION OF INDOOR ROBOT

摘要

A method and a device for recognizing the location of a robot indoors are provided to facilitate the installation and reduce costs, by using two transmitters. A device for recognizing the location of a moving robot(100) indoors includes a first transmitter(110) and a second transmitter(120). The first transmitter delays a received signal by a predetermined time and transmits the delayed signal. The second transmitter delays the received signal by a predetermined time and transmits the delayed signal. The moving robot transmits the signal to the first and second transmitters and identifies its location based on the time required for receiving the signals from the first and second transmitters, respectively.
