Abstract: A robot system includes: a conveying device configured to convey a workpiece; a robot configured to execute an operation on the workpiece; and circuitry configured to: identify a current position of the workpiece and an object area occupied by an object; identify an interlock area that moves with the current position of the workpiece being conveyed by the conveying device; check an overlap between the interlock area and the object area; and control the robot to execute the operation based on the current position of the workpiece in response to determining that the interlock area does not overlap the object area.

Abstract: In an object detecting method according to an embodiment, external reference points are set in external space of a model of an object and an internal reference point is set in internal space of the model. A table is stored in which feature quantities on a local surface of the model are associated with positions of the external reference points and the internal reference point. The feature quantity on the local surface of the model is calculated, and the position of the reference point whose feature quantity is identical to the calculated feature quantity is acquired from the table and is converted into a position in a real space. When the converted position is outside the object, the position is excluded from information for estimation and the position and the attitude of the object are estimated.

Abstract: A recognition program evaluation device includes an imaginary data acquisition portion to generate or acquire imaginary scene data that includes position data of each of a plurality of workpieces and indicates the plurality of workpieces in a randomly stacked state. An imaginary recognition portion recognizes each of the plurality of workpieces indicated in the randomly stacked state using a recognition program including at least one parameter set to adjust recognition of the plurality of workpieces. A recognition evaluation portion compares the position data of each of the plurality of workpieces with a result of recognition of each of the plurality of workpieces recognized by the imaginary recognition portion so as to evaluate recognition performance of the recognition program. A result display portion causes a display of a result of evaluation of the recognition performance of the recognition program evaluated by the recognition evaluation portion.
