Abstract:
A workpiece picking device includes a sensor measuring a plurality of workpieces randomly piled in a three-dimensional space; a robot folding the workpieces; a hand mounted to the robot and hold the workpieces; a holding position posture calculation unit calculating holding position posture data of a position and a posture to hold the workpieces by the robot based on an output of the sensor; a loading state improvement operation generation unit generating loading state improvement operation data of improving a loading state of the workpieces by the robot based on an output of the sensor; and a robot control unit controlling the robot and the hand. The robot control unit controls the robot and the hand based on an output of the holding position posture calculation unit and the loading state improvement operation generation unit to pick the workpieces or perform a loading state improvement operation.

Claim (Index 3):
The workpiece picking device according to  claim 1 , further comprising:\n an operation candidate output unit which includes the at least one holding position posture calculation unit and the at least one loading state improvement operation generation unit and outputs at least one operation candidate; and an operation determination unit which determines one operation from the at least one operation candidate as outputted from the operation candidate output unit and controls the robot through the robot control unit on the basis of the operation as determined, wherein the operation determination unit includes a first machine learning device which performs machine learning to learn an operation determination of determining one operation from at least one operation candidate outputted by the operation candidate output unit, and the first machine learning device includes: a first state observation unit which observes, as state data, measurement data obtained by the sensor, holding position posture data based on an output of the at least one holding position posture calculation unit, and loading state improvement operation data based on an output of the at least one loading state improvement operation generation unit; a first determination data obtaining unit which obtains, as determination data, time data relative to handling which is a series of operations of picking the workpieces by the robot and the hand; and a first learning unit which learns an operation determination of determining one operation from at least one operation candidate outputted by the operation candidate output unit on the basis of the state data obtained by the first state observation unit and the determination data obtained by the first determination data obtaining unit.
