Title:
MOBILE BODY SYSTEM AND SELF-PROPELLED DEVICE AND POSITIONING METHOD OF SELF-PROPELLED DEVICE
Document Type and Number:
Japanese Patent JP2019133240
Kind Code:
A
Abstract:
To provide a mobile body system capable of stably arranging a self-propelled device at a specific position, a self-propelled device, and a positioning method of the self-propelled device.SOLUTION: In a mobile body system 10 having a self-propelled device 11 that is self-propelled and placed in a specific position P, the self-propelled device 11 includes: a geomagnetic sensor A arranged at a height that can detect the magnetic field of magnets 12 and 12a provided in the vicinity of the specific position P or the specific position P; a geomagnetic sensor B placed at a height where a distance in the height direction to the magnets 12 and 12a is longer than a distance in the height direction from the geomagnetic sensor A to the magnets 12 and 12a so that the magnetic field of the magnets 12 and 12a cannot be detected; a direction switching mechanism 23 that changes the traveling direction of the self-propelled device 11; and control means 22 for calculating the position of the self-propelled device 11 with respect to the magnets 12 and 12a based on a value of a difference between measured values of the geomagnetic sensors A and B subtracted by a difference between measured values of the geomagnetic sensors A and B measured in advance in a space where only the geomagnetism is detected as the magnetic field.SELECTED DRAWING: Figure 4
