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.
