Abstract: An information processing device includes a controller. The controller is configured to generate, when information related to a request to use a cabin unit is acquired from a terminal of a first user who intends an activity in the cabin unit rather than traveling by the cabin unit, a command for causing a traveling unit to pick up the first user. The traveling unit is connected to and carrying a predetermined cabin unit associated with the activity of the first user. The controller is configured to generate, to the traveling unit connected to the predetermined cabin unit where a predetermined number of the first users or more is riding, a command for placing the predetermined cabin unit at a predetermined location.

Abstract: A control unit is provided that executes: acquiring a first request that is a request based on information regarding a physical condition of a user using a bed unit that functions as a bed for the user, and that is a request to move the bed unit from a house of the user to a hospital; when having acquired the first request, selecting a first traveling unit that is a traveling unit that moves the bed unit from the house to the hospital and that is a traveling unit located within a predetermined distance from the bed unit; and generating a command for the first traveling unit such that the first traveling unit carries the bed unit from the house to the hospital.

Abstract: An apparatus includes a control section that performs: acquiring information related to a purpose of use of a passenger cabin part, the purpose of use being intended by a user who rides in the passenger cabin part; and setting a control parameter of a traveling part that carries the passenger cabin part, based on information related to a behavior of the user in the passenger cabin part, and on the information related to the purpose of use intended by the user.

Abstract: A control unit is provided that executes: acquiring a first direction that is a direction of the sun as seen from a vehicle that is traveling; acquiring preference data indicating a preference of a user regarding sunlight, the user being moved by the vehicle; and issuing an operation command to an actuator that changes a rotation angle of a seat, in which the user is seated, with respect to the vehicle, based on the first direction and the preference data.

Abstract: An information processing apparatus disclosed has a controller equipped with at least one processor. The controller is configured to execute the processing of; when a vehicle body unit on which a cultivation field for cultivating a crop is mounted is laid at a first place, determining a time to remove defined as a time to remove the vehicle body unit from the first place to a second place other than the first place; and sending a transportation command to a chassis unit configured to be capable of travelling autonomously and being coupled to and decoupled from any vehicle body unit in accordance with the time to remove, the transportation command being a command to transport the vehicle body unit from the first place to the second place.

Abstract: An information processing device includes one or more processors configured to execute: instructing, to a first vehicle platform, a first operation for transporting a vehicle cabin unit which is prescribed to a prescribed place; acquiring, from the vehicle cabin unit, a degree of achievement of an activity of a user performed in the vehicle cabin unit; and instructing, to a second vehicle platform, a second operation for collecting the vehicle cabin unit when the degree of achievement exceeds a prescribed value.

Abstract: A piston includes: a piston head; and a piston skirt connected to the piston head, wherein the piston skirt includes wall portions protruding outward from a surface of the piston skirt, the wall portions adjacent to each other in a circumferential direction of the piston skirt are inclined in directions opposite to each other with respect to a direction of movement of the piston in a bore for the piston, and define a tapered portion, and the tapered portions are spaced away from each other in the circumferential direction of the piston skirt.

Abstract: A hardfacing alloy satisfies the following condition when the hardfacing alloy as a whole is 100 mass % (also simply referred to as “%,” hereinafter), Ni: 10-25%, Si: 1-3%, Fe: 3-18%, the total of one or more elements of Mo, W, and Nb: 6.5-20%, and the balance: Cu and impurities. In particular, it preferably satisfies Fe+2Mo?22.6(%), Mo equivalent/Fe?1.17, and Mo equivalent=Mo+0.522W+1.033Nb. In a hardfacing part composed of the hardfacing alloy, coarse hard particles are formed to ensure the wear resistance, and a soft phase present in the hard particles ensures the machinability. This may be understood as a raw material powder for hardfacing treatment and may also be understood as a hardfacing member in which a hardfacing part is formed on a base material using the raw material powder.
