The control device 1A mainly includes a determination meansA, an abstract state setting meansA, and a sequence generation meansA. The determination meansA determines, based on at least one of environment information relating to environment observed in a workspace of a controlled device to be controlled, state information relating to a state of the controlled device, and stored information that is stored information relating to the objective task to be executed by the controlled device, whether or not the objective task can be completed. The abstract state setting meansA sets, when determined that the objective task cannot be completed, an abstract state in the workspace based on at least one of the environment information or the stored information. The sequence generation meansA generates, based on the abstract state and the objective task, a sequence of subtasks to be executed by the controlled device.

Control device, control method and storage medium

A control deviceA mainly includes a display control meansA and an operation sequence generation meansA. The display control meansA is configured to transmit display information Srelating to a task to be executed by a robot to a display deviceA. The operation sequence generation meansA is configured, in a case that the display control meansA has received, from the display deviceA, task designation information that is input information which schematically specifies the task, to generate an operation sequence to be executed by the robot based on the task designation information Ia.

What is disclosed is a motion model calculation device which easily creates a motion model for a drive device. The motion model calculation device is connected to a robot arm including a plurality of arms and a joint mechanism which pivotally joins the plurality of arms to a connection part, outputs a predetermined motion command to the joint mechanism, acquires a driving state of the joint mechanism caused by a motion corresponding to the motion command, and calculates, on the basis of the motion command and the driving state, a motion model representing the relationship between an input value representing an input to the joint mechanism and an output value of the joint mechanism with respect to the input.

This flow control system is obtained by connecting a plurality of work units WU&#x3b1; and a plurality of work units WU&#x3b2; to one another, wherein: each WU&#x3b1; has an &#x3b1;-control purpose which is a WU-based independent control purpose, and has an &#x3b1;-control rule for the &#x3b1;-control purpose; each WU&#x3b2; has a &#x3b2;-control purpose to cause as many WU&#x3b1; as possible to achieve the own &#x3b1;-control purposes, and has a &#x3b2;-control rule for the &#x3b2;-control purpose; the &#x3b2;-control rule is dynamically changed on the basis of partial information about the flow control system; and the WU&#x3b2; is disposed in a part of the flow control system.

Flow control system and control method therefor

Provided is a work management device for arranging a worker in consideration of a change of work efficiency. In a work management device, an index acquisition unitacquires, for each work section, a work evaluation index calculated based on work history performed by a worker. A duration time acquisition unitacquires a duration time for which a work status of the worker is the work evaluation index. A cost acquisition unitacquires a cost incurred when the worker moves between the work sections. A determination unitacquires an estimated work amount performed by the worker until the duration time is elapsed. The determination unitdetermines, based on the estimated work amount and cost, arrangement of the workers in the plurality of work sections in such a way as to increase work efficiency in a whole of a work range.
