Abstract: A robot control system comprising circuitry configured to acquire a designated area image showing a designated area, and execute image analysis on the designated area image to detect a current state of the designated area as a current area state. The circuitry is further configured to generate, based on the current area state, a state of the designated area which simulates one or more objects including an additional object as having been placed in the designated area, as a predicted area state. The circuitry is further configured to generate object information on the additional object which is simulated in the designated area, based on the predicted area state. The circuitry is further configured to control a robot so as to physically place the additional object in the designated area in accordance with the object information.

Abstract: A motor control device that can use a sensor input circuit that has a low response speed. The motor control device comprises a first magnetic pole position detection unit, a second magnetic pole position detection unit, and a control unit. The first magnetic pole position detection unit detects the pre-rotation position of a magnetic pole of a rotor based on detection results from a magnetic pole sensor. The second magnetic pole position detection unit detects the position of the magnetic pole of the rotor based on the current flowing in a plurality of drive windings that drive the rotor. The control unit performs control that makes the rotor start rotating based on detection results from the first magnetic pole position detection unit and control that makes the rotating rotor rotate based on detection results from the second magnetic pole position detection unit.
