POSITIONAL DISPLACEMENT DETECTOR, ROBOT HAND, AND ROBOT SYSTEM

摘要

Provided is a positional displacement detector 20, a robot hand 10, and a robot system 64 that are capable of detecting an object's positional displacement equal to or beyond a set range. The positional displacement detector 20 includes a contact member 22, a prohibition member 24, and a vibration detector 26. The contact member 22 is configured to make contact with the object and deform with a positional displacement of the object. The prohibition member 24 is configured to make contact with the deformed contact member 22 to prohibit a deformation of a magnitude equal to or more than a predetermined magnitude from being caused to the contact member 22. The vibration detector 26 is configured to detect a vibration generated when the contact member 22 has made contact with the prohibition member 24.
