Abstract: A communication terminal for remotely operating a mobile apparatus, includes circuitry that receives a remote operation to be performed on an operation target of the mobile apparatus, and transmits operation information indicating the remote operation to be performed on the operation target to remotely operate the operation target, the operation target being a target to which an operation right that is exclusive is to be applied.

Abstract: A farmland management system includes an information detection unit configured to acquire information relating to a crop being cultivated, a storage unit configured to store crop registration information for estimating a growth condition of the crop, a growth estimation unit configured to refer to the crop registration information and estimate the growth condition of the crop based on the information relating to the crop and the crop registration information, and a display unit configured to display the growth condition estimated by the growth estimation unit.

Abstract: A system includes a first operation device configured to perform an operation with respect to a first target; at least one sensor configured to acquire analog information from the first target; and a control device configured to identify the first target based on at least one type of first digital information among a plurality of types of digital information relating to the first target acquired from the analog information acquired by the at least one sensor, and control the operation by the first operation device with respect to the first target identified based on at least one type of second digital information different from the first digital information among the plurality of types of the digital information.

Abstract: An information processing apparatus includes an obtainment unit configured to obtain spectroscopic information generated from image information of a plant captured by an imaging unit; and a generation unit configured to generate a control signal for controlling a degree of water stress of the plant, based on the obtained spectroscopic information.
