Abstract: A control unit of a server device as an information processing apparatus is configured to: provide first information on a service for each of a plurality of moving objects, each of which is configured to provide a different service and autonomous travel; acquire second information on time and location of at least one service that a user wants to use; and determine at least one moving object that matches with the user based on the first information and the second information, and generate a travel plan of the at least one moving object.

Abstract: A measurement method includes: a data acquisition step of acquiring position data output from a measurement device configured to move round-trip on a movement route and measure a position of an object in a periphery of the movement route, the measurement device using a plane having a depression angle or an elevation angle with respect to a plane that is orthogonal to a forward direction as a measurement target; and a point group data generation step of generating point group data for an object in the periphery of the movement path using the position data obtained during movement of the measurement device on an outbound trip and position data obtained during movement of the measurement device on a return trip.

Abstract: A measurement device configured to move along a movement path and measure the position of an object in surroundings of the movement path includes: a measurement unit configured to measure the position of the object with a plurality of surfaces as measurement targets, the plurality of surfaces facing in directions different from each other; and a point group data generation unit configured to generate point group data of the object in surroundings of the movement path by using positional data representing the position of the object measured by the measurement unit.

Abstract: The present inventors have found the presence of a nanobubble that has not been confirmed conventionally, and established a method for producing nanobubbles. The inventors have determined the theoretically expected characteristics of the produced nanobubbles, found new characteristics by analyzing data experimentally collected, and elucidated the relationship among the characters. Specifically, the inventors have found that a nanobubble has features such as decrease of the buoyant force, increase of the surface area, increase of the surface activity, generation of a local high-pressure field, interface activating action, and sterilizing action thanks to electrostatic polarization. By the association among the features, any of wide variety of objects can be cleaned with high performance and with light environmental load thanks to the function of adsorbing foul components, the function of cleaning the surface of an object quickly, and the sterilizing function, and polluted water can be purified.
