Abstract

A conveyance system includes a plurality of conveyance robots, a storage unit, a stability information acquisition unit, a selection unit, and a system controller, which serves as a controller. The plurality of conveyance robots convey a wagon that accommodates a conveyed object. The storage unit stores robot information regarding features that the plurality of respective conveyance robots include. The stability information acquisition unit acquires stability information regarding stability when the conveyed object is conveyed. The selection unit selects one of the plurality of conveyance robots based on the robot information and the stability information that have been acquired. The system controller instructs the one conveyance robot that has been selected to convey the conveyed object.

First claim

What is claimed is:

1 . A conveyance system comprising:
a plurality of conveyance robots configured to convey a wagon that accommodates a conveyed object; a storage unit configured to store robot information regarding features that the plurality of respective conveyance robots include; a stability information acquisition unit configured to acquire stability information regarding stability when the conveyed object is conveyed; and a selection unit configured to select one of the plurality of conveyance robots based on the robot information and the stability information that have been acquired; and a controller configured to instruct the one conveyance robot that has been selected to convey the conveyed object.

2 . The conveyance system according to claim 1 , wherein the stability information acquisition unit accepts an input from a user regarding the stability information, thereby acquiring stability information.

3 . The conveyance system according to claim 1 , wherein
the storage unit stores each of reference image data of the conveyed object and information regarding the stability that corresponds to the reference image data in advance, the stability information acquisition unit acquires image data obtained by capturing images of the conveyed object as the stability information, and the selection unit compares the image data of the conveyed object with the reference image data to determine the stability of the conveyed object.

4 . The conveyance system according to claim 1 , wherein
the storage unit stores features of a raising/lowering mechanism for raising and/or lowering the wagon that each of the plurality of conveyance robots includes as the robot information, and the selection unit selects the one conveyance robot based on the features of the raising/lowering mechanism that each of the plurality of conveyance robots includes.

5 . The conveyance system according to claim 1 , wherein
the storage unit stores information regarding operation accelerations of the plurality of respective conveyance robots as the robot information, and the selection unit selects the one conveyance robot based on the information regarding the operation accelerations that the plurality of respective conveyance robots include.

6 . A conveyance method for selecting one of a plurality of conveyance robots configured to convey a wagon that accommodates a conveyed object and causing the one conveyance robot to convey the wagon, the conveyance method comprising:
a storing step for storing robot information regarding features that the plurality of respective conveyance robots include; a stability information acquisition step for acquiring stability information regarding stability when the conveyed object is conveyed; a selecting step for selecting one of the plurality of conveyance robots based on the robot information and the stability information that have been acquired; and a control step for instructing the one conveyance robot that has been selected to convey the conveyed object.

7 . A non-transitory computer readable medium storing a program for causing a computer to execute a conveyance method for selecting one of a plurality of conveyance robots configured to convey a wagon that accommodates a conveyed object and causing the one conveyance robot to convey the wagon, the conveyance method comprising:
an information storing step for storing robot information regarding features that the plurality of respective conveyance robots include; a stability information acquisition step for acquiring stability information regarding stability when the conveyed object is conveyed; a selecting step for selecting one of the plurality of conveyance robots based on the robot information and the stability information that have been acquired; and a control step for instructing the one conveyance robot that has been selected to convey the conveyed object.
