1. A mobile robot control system, the system comprising:
- a generator configured to generate multiple, sequential emissions;
a transducer in communication with the generator configured to transmit emissions of the generator and to receive reflections of transmitted emissions;
a conditioner in communication with the transducer to condition received reflections; and
a processor in communication with the conditioner configured to;
obtain a threshold value based on a latest one of the reflections and previously received ones of the reflections determined to fall within a predetermined range of the latest reflection,determine if the latest reflection is a result of a latest one of the outputted emissions based on the threshold value, andcontrol the mobile robot based on the determination of whether the latest reflection is a result of the latest outputted emission.

Abstract
Detecting an object using sound waves includes outputting a sound wave from a transducer, receiving an echo after outputting the sound wave, obtaining a threshold value based on the echo and plural other echoes that are within a predetermined range of the echo, and determining if the echo is a result of the sound wave based on the threshold value.

22. A method of controlling a mobile robot, the method comprising:
-
outputting multiple, sequential emissions from a scanner; receiving reflections of the outputted emissions with the scanner; obtaining a threshold value based on a latest one of the reflections and previously received ones of the reflections determined to fall within a predetermined range of the latest reflection; determining if the latest reflection is a result of a latest one of the outputted emissions based on the threshold value; and controlling the mobile robot based on the determination of whether the latest reflection is a result of the latest outputted emissions, wherein the scanner comprises; an emission generator; a transducer in communication with the generator to transmit generated emissions and to receive emission reflections; and a conditioner in communication with the transducer and configured to condition received reflections.

23. A method of controlling a mobile robot, the method comprising:
-
receiving plural reflections of corresponding emissions with a scanner; determining a threshold value based on a target reflection and received reflections determined to each result from a corresponding emission; determining if the target reflection is a reflection of a latest emission; and controlling the mobile robot based on the determination of whether the target reflection is a reflection of the latest emission, wherein the scanner comprises; an emission generator; a transducer in communication with the generator to transmit generated emissions and to receive emission reflections; and a conditioner in communication with the transducer and configured to condition received reflections. - View Dependent Claims (24, 25)
