Method for causing robot to fit male component in female component

A method of fitting a male component to a female component by a robot,

• the male component including:
• a base part;
• and
• a plurality of shaft parts attached to the base part, the plurality of shaft parts being movable in an axial direction thereof with respect to the base part and being hooked at predetermined positions so as to be not able to move in one direction of the axial direction,
• the female component including:
• a top face;
• and
• a plurality of holes formed to be recessed from the top face and arranged to be able to receive the plurality of shaft parts respectively,
• the method comprising:
• grasping the base part by the robot and arranging the base part at vertically upward of the top face of the female component so that the plurality of shaft parts are suspended at vertically downside from the base part in a state where the plurality of shaft parts are hooked at the predetermined positions so as to be not able to move in the axial direction toward vertically downward;
• moving the base part vertically downward by the robot so that a bottom face of the base part approaches the top face of the female component;
• and
• reciprocating all of portions of the base part, from which the shaft parts are suspended, in a first direction parallel to a horizontal direction and a second direction opposite the first direction, along with moving the base part vertically downward by the robot, so that a tip end of at least one shaft part slides on the top face of the female component along a pathway which passes the hole if the tip end of the at least one shaft part is not inserted into the hole so as to butt against the top face of the female component when moving the base part vertically downward by the robot.
