A handling device according to an embodiment has an arm, a holder, a storage, and a controller. The arm includes at least one joint. The holder is attached to the arm and is configured to hold an object. The storage stores a function map including at least one of information about holdable positions of the holder and information about possible postures of the holder. The detector is configured to detect information about the object. The controller is configured to generate holdable candidate points on the basis of the information detected by the detector, to search the function map for a position in an environment in which the object is present, the position being associated with the generated holdable candidate points, and to determine a holding posture of the holder on the basis of the searched position. The function map associates a manipulability with each position in the environment in which the object is present. The manipulability is a parameter calculated from at least one joint angle of the holder.

A grasping error correction method includes a position information acquisition step of acquiring position information of a plurality of areas of a lower component 2, a grasping error value calculation step of calculating a grasping error value based on the position information at the time of the reproduction and the position information of the plurality of areas of the lower component 2 at the time of teaching, and an arm control step of controlling an operation of a multi-axis articulated arm 11a so as to correct the grasping error value. Further, in the grasping error value calculation step, the grasping error value is calculated so that a grasping error in a processing nearby area, which is one of the plurality of areas of the lower component 2 that is closest to the processing area, is preferentially eliminated over those in the other areas of the lower component 2.

When one of the objects placed on a placement board is sucked and held by a suction nozzle and is taken out by an actuator under the control of an operation controller, a first acquirer acquires a difference M between a first moment M1 applied to the suction nozzle and a second moment M2 applied to the suction nozzle when the object is taken out by the suction nozzle by a first taking-out movement distance. The operation controller performs control, based on the acquired difference between the moments, whether the taking-out operation is to be further continued.
