Abstract: A robot controller includes a Web API (Application Programming Interface) configured to receive a request from a Web client which is configured to execute a Single Page Application, response generation circuitry configured to generate a response to the request as updated data for the Single Page Application, and processing circuitry configured to execute a process with respect to a robot. The process corresponds to the request received by the Web API.

Abstract: An electronic device comprises a rechargeable battery, a display, and a power generation unit. The display can display a screen and change luminance of the screen. The power generation unit generates electrical power upon receiving solar light. The display includes a first light emitting unit to which electrical power is supplied from the power generation unit to emit light and a second light emitting unit to which electrical power is supplied from the battery to emit light. The display changes a screen to be bright when the electrical power supplied from the power generation unit becomes large, and darken the screen when the electrical power supplied from the power generation unit becomes small.

Abstract: An electronic apparatus is disclosed. An electronic apparatus includes: a touch area on a surface of the electronic apparatus; a fingerprint sensor; and at least one processor. The at least one processor is configured to: execute a first operation of an application; cause the fingerprint sensor to detect a touch of a finger of a user on the touch area; cause the fingerprint sensor to obtain a fingerprint of the finger in response to the detection of the touch; cause the fingerprint sensor to measure a force of the finger to the touch area, and change the first operation in accordance with the force if the fingerprint is identical to a predetermined fingerprint.
