Autonomous movement system, autonomous movement method, and autonomous movement program

An autonomous movement system comprising:

• an autonomous movement device that performs autonomous movement in a facility including an elevator;
• and
• a server device that exchanges traveling information with the autonomous movement device, wherein
• the server device moves a waiting position of the autonomous movement device in a car of the elevator, based on a person that gets on the car or an object that gets on the car;
• the server device transmits, to the autonomous movement device, a signal to
• (i) move the autonomous movement device in the car to the waiting position such that the autonomous movement devices are arrayed along a direction in which the object extends before the car stops at the floor or before the door of the car opens, the object being a stretcher, or
• (ii) in the case where the server device determines the person uses a handrail in the car, move the autonomous movement device in the car to the waiting portion positioning at a predetermined distance away from the handrail before the car stops at the floor or before the door of the car opens;
• the autonomous movement device in the car moves the waiting position before the car stops at the floor or before the door of the car opens.

An autonomous movement method for an autonomous movement device that performs autonomous movement in a facility including an elevator, the autonomous movement method comprising:

• a step of determining, in a car of the elevator, a person that gets on the car or an object that gets on the car;
• a step of moving a waiting position in the car, based on the person or the object;
• a step of determining the person or the object before the car stops at a floor or before a door of the car opens;
• and
• a step of:
• (i) moving the autonomous movement device in the car to the autonomous movement device such that the autonomous movement devices are arrayed along a direction in which the object extends before the car stops at the floor or before the door of the car opens, the object being a stretcher, or
• (ii) moving the autonomous movement device in the car to the waiting portion positioning at a predetermined distance away from the handrail before the car stops at the floor or before the door of the car opens, in the case where it is determined that the person uses the handrail in the car.

A non-transitory storage medium storing instructions that are executable by one or more processors and that cause the one or more processors to perform functions comprising:

• determining, in a car of the elevator, a person that gets on the car or an object that gets on the car;
• determining the person or the object before the car stops at a floor or before a door of the car opens;
• and
• (i) moving the autonomous movement device in the car to the waiting position such that the autonomous movement devices is are arrayed along a direction in which the object extends before the car stops at the floor or before the door of the car opens, the object being a stretcher, or
• (ii) in the case where it is determined that the person uses a handrail in the car, moving the autonomous movement device in the car to the waiting position from a vicinity of the handrail to the front of a car door before the car stops at the floor or before the door of the car opens.
