Claims (5)

1. 1 . A system comprising: a control unit configured to control a mobile body movable by unattended driving by using sensor information acquired from a sensor; and an inspection unit configured to inspect a manufacturing status of the mobile body by using at least one of the sensor information and electronic component information acquired from an electronic component mounted on the mobile body.
2. 2 . The system according to claim 1 , wherein the control unit is configured to change a movement destination of the mobile body based on an inspection result from the inspection unit.
3. 3 . The system according to claim 1 , wherein the inspection unit is configured to determine progress of a manufacturing process for the mobile body and inspect an item corresponding to the progress.
4. 4 . The system according to claim 1 , wherein the inspection unit is configured to identify a component to be mounted on the mobile body and make inspection as to whether the component to be mounted on the mobile body is mounted on the mobile body.
5. 5 . A method comprising: controlling a mobile body movable by unattended driving by using sensor information acquired from a sensor; and inspecting a manufacturing status of the mobile body by using at least one of the sensor information and component information acquired from an electronic component mounted on the mobile body.

Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims priority to Japanese Patent Application No. 2023-161806 filed on Sep. 26, 2023, incorporated herein by reference in its entirety. BACKGROUND 1. Technical Field The present disclosure relates to a system and a method. 2. Description of Related Art A technique for remotely controlling a vehicle to travel in a vehicle manufacturing process is known in the art (e.g., Japanese Unexamined Patent Application Publication (Translation of PCT Application) No. 2017-538619 (JP 2017-538619 A)). SUMMARY In a manufacturing process for a mobile body such as a vehicle, when the manufacturing status of the mobile body is visually checked by an operator, it takes time and cost to arrange the operator. In a case of checking by a dedicated facility instead of by an operator, it takes time and cost to arrange the dedicated facility. Therefore, there is a demand for a technique capable of checking the manufacturing status of a mobile body regardless of an operator or a dedicated facility. The present disclosure can be implemented in the following aspects. (1) According to a first aspect of the present disclosure, a system is provided. The system includes: a control unit configured to control a mobile body movable by unattended driving by using sensor information acquired from a sensor; and an inspection unit configured to inspect a manufacturing status of the mobile body by using at least one of the sensor information and electronic component information acquired from an electronic component mounted on the mobile body. With the system of this aspect, it is possible to inspect the manufacturing status of the mobile body regardless of an operator or a dedicated facility.(2) In the system of the above aspect, the control unit may be configured to change a movement destination of the mobile body based on an inspection result from the inspection unit. With the system of this aspect, the movement destination of the mobile body can be varied based on the inspection result.(3) In the system of the above aspect, the inspection unit may be configured to determine progress of a manufacturing process for the mobile body and inspect an item corresponding to the progress. With the system of this aspect, it is possible to make the inspection based on the progress of the manufacturing process.(4) In the system of the above aspect, the inspection unit may be configured to identify a component to be mounted on the mobile body and make inspection as to whether the component to be mounted on the mobile body is mounted on the mobile body. With the system of this aspect, it is possible to reduce the occurrence of a case where the mounting of the component on the mobile body is forgotten.(5) According to a second aspect of the present disclosure, a method is provided. The method includes: controlling a mobile body movable by unattended driving by using sensor information acquired from a sensor; and inspecting a manufacturing status of the mobile body by using at least one of the sensor information and component information acquired from an electronic component mounted on the mobile body. With the method of this aspect, it is possible to inspect the manufacturing status of the mobile body regardless of an operator or a dedicated facility. The present disclosure can be implemented in various forms other than the system and the method. For example, the present disclosure can be implemented in the form of a device, a computer program, or a recording medium on which the computer program is recorded.
