Abstract
A gripping apparatus is configured to grip an object by a claw. The gripping apparatus includes an electric circuit passing through a first claw body, the object, and a second claw body, and a conduction judgment part for judging as to whether or not the electric circuit is electrically conductive. The electric circuit is shut off by a protective member, which protects the object, but becomes electrically conductive when the claw bodies and the object are in direct contact with each other.

- a claw configured to releasably grip an object;
- and
- a protective member configured to protect the object, the protective member being attached to the claw, such that when the object is gripped by the claw, the protective member is provided between the claw and the object,
- wherein the protective member is an electrical insulator,
- wherein the gripping apparatus further comprises:
- an electric circuit configured to pass through the claw and the object when the object is gripped by the claw;
- and
- a conduction judgment part configured to judge as to whether or not the electric circuit is electrically conductive, and
- wherein the electric circuit is configured to become electrically conductive when the protective member is worn out or impaired and causes the claw and the object to come into direct contact with each other.
