Abstract: In a work management device, a first storage unit stores a first learned model that outputs a plurality of objects defining each of a plurality of work states forming one process of manufacturing work with respect to a determination target image including a hand image that is an image of a hand of a worker who is performing a product manufacturing work, a detection unit detects the plurality of objects with respect to the determination target image by using the first learned model, and a determination unit determines a work state indicated by the determination target image based on the plurality of objects detected by the detection unit.

Abstract: An assembling device for supplying and assembling a part on an object has a table and a first moving portion disposed above the table, where the first moving portion includes a guide and a movable body. The guide extends in a first direction parallel to a surface of the table out of a range in which the table is positioned. The movable body is movable to a position out of the range in which the table is positioned. The assembling device also has a second moving portion disposed on the table and movable in a second direction transverse to the first direction, the object being mounted on the second moving portion.

Abstract: A numerical control apparatus for a robot which controls an overlapping operation of the robot executed to minimize the tact time while bypassing an obstacle and which allows an operation program for the robot to be produced easily is provided. The commands of the robot program include an overlapping operation starting point designating instruction which instructs the robot of an overlapping operation which starts from a position of a designated ratio of a preceding single operation, and an overlapping operation ending point designating instruction which instructs the robot of the overlapping operation which ends at a position of a designated ratio of a following single operation. Any overlapping operation of the robot is performed in accordance with either one of the instructions.
