Abstract

Execution restrictions on tasks based on a state of a multifunction robot or the like are satisfied, and furthermore, the execution efficiency of the entirety of an operation is also enhanced. An information processing device includes a determination unit that determines an execution order of a plurality of tasks including an operation for a target object, based on a transition of a state of an operation tool used in each of the tasks.

First claim

The invention claimed is:

1. An information processing device, comprising:
a determination unit configured to determine a first execution order of a plurality of tasks including an operation for a target object, based on
a transition of a state of an operation tool used in each of the tasks, wherein the state of the operation tool is a hygienic state of the operation tool; and

a control unit configured to control hygiene state transition based on a determination that a first food item of a plurality of food items is forbidden from coming into contact with a second food item of the plurality of food items.

2. The information processing device according to claim 1 , wherein the state of the target object is a hygienic state of the target object.

3. The information processing device according to claim 1 , further comprising:
a state transition storage unit configured to store therein a transition of a state of the operation tool in each of the plurality of tasks; and
a task information storage unit configured to store therein information on the plurality of tasks, wherein
the determination unit is further configured to determine the first execution order of the plurality of tasks, based on
the transition of the state of the operation tool in each of the plurality of tasks, the transition of the state being stored in the state transition storage unit, and
the information on the plurality of tasks, the information being stored in the task information storage unit.

4. The information processing device according to claim 1 , further comprising:
a state transition storage unit configured to store therein a transition of a state of the operation tool in each of the plurality of tasks and a transition of a state of the target object in each of the plurality of tasks; and
a task information storage unit configured to store therein information on the plurality of tasks, wherein
the determination unit is further configured to determine the first execution order of the plurality of tasks, based on
the transition of the state of the operation tool in each of the plurality of tasks and the transition of the state of the target object in each of the plurality of tasks, the transition of the state of the operation tool and the transition of the state of the target object being stored in the state transition storage unit, and
the information on the plurality of tasks, the information being stored in the task information storage unit.

5. The information processing device according to claim 1 , further comprising:
an initial state storage unit configured to store therein an initial state of the operation tool, wherein
the determination unit is further configured to manage a transition of the state from the initial state of the operation tool, the initial state being stored in the initial state storage unit.

6. The information processing device according to claim 1 , further comprising a control unit configured to control execution of the plurality of tasks, based on the first execution order determined by the determination unit.

7. The information processing device according to claim 6 , wherein,
when a new task is added to the plurality of tasks during the control by the control unit,
the determination unit is further configured to determine a second execution order, the second execution order includes the new task along with the plurality of tasks, and
the control unit is further configured to control the execution, based on the second execution order determined by the determination unit.

8. The information processing device according to claim 1 , wherein
the target object is food,
the operation tool is kitchenware and an arm of a robot,
the plurality of tasks includes: a cooking operation included in a recipe; and washing of the kitchenware and the arm,
the state includes a plurality of stages, and
the transition is caused by contact between at least two of the kitchenware, the arm, and the food.

9. A scheduling method, comprising:
determining an execution order of a plurality of tasks including an operation for a target object, based on
a transition of a state of an operation tool used in each of the tasks, wherein the state of the operation tool is a hygienic state of the operation tool; and

controlling hygiene state transition based on a determination that a first food item of a plurality of food items is forbidden from coming into contact with a second food item of the plurality of food items.

10. A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by a computer, cause the computer to execute operations, the operations comprising:
determining an execution order of a plurality of tasks including an operation for a target object, based on
a transition of a state of an operation tool used in each of the tasks, wherein the state of the operation tool is a hygienic state of the operation tool; and

controlling hygiene state transition based on a determination that a first food item of a plurality of food items is forbidden from coming into contact with a second food item of the plurality of food items.
