Abstract: An autonomous mobile robot linkage system (1) includes a plurality of sign posts (SP0 to SP2) disposed along a travel path (10); an autonomous mobile robot (20) which moves along the travel path (10) while reading the plurality of sign posts (SP0 to SP2) in order using a camera and performs predetermined operations in order of pre-set operation numbers based on identification numbers read from the sign posts (SP0 to SP2); and a host device (30) which receives information on the operation number being executed from the autonomous mobile robot (20) and generates an event on the travel path (10) based on the operation number.

Abstract: A control device for a linear motor includes a speed controller that calculates a current command value by an integration operation using a first integral value of a difference between a moving speed of a movable element provided in the linear motor and a speed command value calculated on the basis of a position command value, a current controller that applies a voltage to the linear motor on the basis of the current command value, and a correction value storage unit that stores the first integral value of the speed controller when the movable element remains at a position indicated by the position command value. When resuming control of the linear motor, the speed controller sets the first integral value stored in the correction value storage unit as an initial value for the integration operation before the brake controller turns off the brake device.

Abstract: This pressing device includes an actuator, a pressing unit provided on a movable element of the actuator, a movement quantity detector for detecting a movement quantity of the movable element and outputting movement quantity information indicating the movement quantity, and a drive device that moves the pressing unit to press a pressed object by supplying a drive current to the actuator based on the movement quantity information. The drive device controls an operation of the pressing unit using position control processing based on current information indicating the drive current and the movement quantity information. When the speed of the pressing unit is decelerated down to a predetermined lower limit speed, the drive device controls the speed of the pressing unit to be constant based on the current information, and when the current reaches a predetermined current value, determines that the pressing operation is performed.
