Abstract

Official abstract text for this publication.

A work picking system according to embodiments includes a three-dimensional measuring unit, a hand, a calculating unit, a determining unit, and an instructing unit. The three-dimensional measuring unit measures a three-dimensional shape of a work that is a gripping target. The hand is provided on a terminal movable unit of a multi-axis robot and includes a mechanism that changes a distance between gripping claws and a mechanism that changes a tip end direction of the gripping claws. The determining unit determines a tip end direction of the gripping claws based on the attitude of the work calculated by the calculating unit and a direction of a rotation axis of the terminal movable unit.
