Robot tool

Abstract

Provided is a robot tool capable of aligning a screw or a gauge with a screw hole even if a position and angle of a screw mating surface are slightly shifted. A robot tool includes: a shaft member provided with, at at least one end thereof, a gauge that inspects a diameter of a screw hole or a bit that tightens and loosens a screw; a motor accommodating, in a cylindrical motor shaft thereof, the shaft member so that the shaft member is raisable and lowerable; a tubular guide that is disposed so as to enable the shaft member to be inserted thereinto and that has a tip to be brought into contact with a screw mating surface; and a force sensor configured to detect a moment applied from the screw mating surface to the guide when part of the tip of the guide is brought into contact with the screw mating surface.

Dependencies are inferred from the claim text.
