Mobile device, mobile device control system, method, and program

A mobile device control system comprising:

• a mobile device;
• and
• a building management server, wherein
• the building management server retains an allowable noise record map on which an allowable noise level corresponding to a position is recorded,
• the mobile device performs traveling speed control according to a traveling position such that a noise level is equal to or lower than the allowable noise level according to the allowable noise record map, and
• the mobile device performs control of changing a traveling speed at least according to a type of manufactured material of a traveling surface.

A mobile device control method performed in a mobile device, the method comprising:

• by a controller of the mobile device,
• receiving input detection information of a sensor mounted on the mobile device;
• determining whether or not an object approaching the mobile device is a human on a basis of the input detection information;
• and
• performing control different between a case where the controller determines that the object is a human and a case where the controller determines that the object is not a human,
• wherein, in response to determining that the object is a human, determining whether the human is oriented full face to the mobile device based on the input detection information,
• in response to determining that the human is oriented full face to the mobile device, controlling the mobile device to approach the human to a first predetermined distance and stop after setting an article mounted in the mobile device in a direction visible to the human, and
• in response to determining that the human is not oriented full face to the mobile device, controlling the mobile device to stop after setting the article mounted in the mobile device in the direction visible to the human at a position separated from the human by a second distance that is greater than the first predetermined distance.

A mobile device control method performed in a mobile device control system including a mobile device and a building management server, the method comprising:

• by the building management server,
• retaining an allowable noise record map on which an allowable noise level corresponding to a position is recorded;
• and
• by the mobile device,
• performing traveling speed control according to a traveling position such that a noise level is equal to or lower than the allowable noise level according to the allowable noise record map, and
• performing control of changing a traveling speed at least according to a type of manufactured material of a traveling surface.

A non-transitory computer readable medium storing a program for making mobile device control processing performed in a mobile device, the program making a controller of the mobile device:

• receive input detection information of a sensor mounted on the mobile device;
• determine whether or not an object approaching the mobile device is a human on a basis of the input detection information;
• and
• perform control different between a case where the controller determines that the object is a human and a case where the controller determines that the object is not a human,
• wherein, when the controller determines that the object is a human, the controller determines whether the human is oriented full face to the mobile device based on the input detection information,
• when the controller determines that the human is oriented full face to the mobile device, the controller controls the mobile device to approach the human to a first predetermined distance and stop after setting an article mounted in the mobile device in a direction visible to the human, and
• when the controller determines that the human is not oriented full face to the mobile device, the controller controls the mobile device to stop after setting the article mounted in the mobile device in the direction visible to the human at a position separated from the human by a second distance that is greater than the first predetermined distance.
