Abstract: An air conditioner includes an outdoor unit, a plurality of indoor units, a plurality of detecting units, an operating device that receives an instruction on use of all prediction results obtained for all of a plurality of spaces, a determining circuitry, and a deciding circuitry. The detecting circuitries each detect a state relating to temperature of an associated space. A prediction result obtained for each of the spaces is a predicted temperature of the space associated with one of the detecting circuitries a predetermined time after a detection result is obtained by the one of the detecting circuitries, which is predicted on the basis of the detection result. When all the prediction results are determined not to be the same, the deciding circuitry determines how air conditioning is to be performed on the basis of part or the whole of all the prediction results in accordance with an instruction received by the operating device.

Abstract: A robot system includes a robot including a main body and a hand. An imaging device picks up an image of a workpiece held by the hand An image pick-up controller sends movement information to a robot controller to move the workpiece held by the robot to a plurality of positions, controls the imaging device to pick up the image of the workpiece at the plurality of positions, recognizes a registered portion of the workpiece at the plurality of positions, and performs a calibration based on the movement information and based on a result of recognizing the registered portion of the workpiece held by the robot at the plurality of positions. The calibration includes correlating positional information of the image picked up by the imaging device to positional information of the robot.

Abstract: A workpiece positioning device according to an embodiment includes a first moving unit that is movable in a horizontal direction, a second moving unit that is movable in a vertical direction, and a rotating unit that is placed on either an upper end or a lower end of the second moving unit. The second moving unit and the rotating unit are kept within the width of the first moving unit that is perpendicular to the moving direction of the first moving unit on a horizontal plane.
