Robot localization system
First Claim
1. A robot localization system including a robot, which moves within a predetermined space and performs predetermined tasks, and a docking station corresponding to a home position of the robot, the docking station comprising:
- a first transmitting unit, which transmits a sound wave to detect a position of the robot; and
a second transmitting unit, which transmits a synchronizing signal right when the sound wave is transmitted, the robot comprising;
a first receiving unit, which comprises at least two sound sensors receiving the sound wave incident onto the robot;
a second receiving unit, which receives the synchronizing signal incident onto the robot;
a distance calculation unit, 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, which calculates an incident angle of the sound wave onto the robot using a difference between receiving times of the sound wave in the at least two sound sensors comprised in the first receiving unit.

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

8. A robot localization system including a robot and a docking station,
the robot comprising: -
a first transmitter which transmits a first radio wave;
a second receiver which receives a second radio wave; and
a distance calculator which calculates a distance between the robot and the docking station, the docking station comprising;
a first receiver which receives the first radio wave; and
a second transmitter which transmits the second radio wave a predetermined period of time after the first radio wave is received, wherein the distance calculator calculates the distance between the robot and the docking station using a difference between an instant of time when the first radio wave is transmitted and an instant of time when the second radio wave is received and a predetermined period of time from the reception of the first radio wave to the transmission of the second radio wave. - View Dependent Claims (9, 10, 11, 12, 13, 14)
