Robot localization system

摘要

A robot localization system is provided. The robot localization includes a robot (310), which moves within a predetermined space and performs predetermined tasks, and a docking station (300) corresponding to a home position of the robot (310). The docking station (300) includes a first transmitting unit (301), which transmits a sound wave to detect a position of the robot; and a second transmitting unit (302), which transmits a synchronizing signal right when the sound wave is transmitted. The robot includes a first receiving unit (311), which comprises at least two sound sensors receiving the sound wave incident onto the robot; a second receiving unit (312), which receives the synchronizing signal incident onto the robot; a distance calculation unit (314), which calculates a distance between the first transmitting unit and the first receiving unit using a difference between an instant of time when the synchronizing signal is received and an instant of time when the sound wave is received; and an incident angle calculation unit (313), which calculates an incident angle of the sound wave onto the robot (310) using a difference between receiving times of the sound wave in the at least two sound sensors comprised in the first receiving unit.
