  • Publication number: 20230066809
    Abstract: A configuration is achieved in which collision risk information is received from a mobile device such as a drone, a modified path with a low collision risk is generated, and movement according to the modified path is performed. Existence of a second mobile device or pedestrian exposed to a collision risk is checked on the basis of collision risk information received from the mobile device such as a drone, and in a case where the existence of the second mobile device or pedestrian exposed to the collision risk is confirmed, collision risk information received from a first mobile device or modified safe circuit information is transmitted to the second mobile device exposed to the collision risk, or transmitted to a user terminal held by the pedestrian exposed to the collision risk. The collision risk information received from the mobile device such as a drone is risk information with which a collision risk corresponding to a three-dimensional spatial position can be analyzed.
