TEACHING POSITION SETTING METHOD AND TEACHING POSITION SETTING DEVICE

A method comprising: a step of repeating a series of operations in which a first component is caused to be moved from a current teaching position horizontally and is caused to be lowered toward a second component, until insertion into an insertion hole is possible; a step of acquiring a position at which the first component was able to be inserted into the insertion hole as an actual initial insertion position; a step of acquiring a provisional center position on the basis of the current teaching position and the actual initial insertion position; a step of acquiring two limit positions in which the first component was inserted into the insertion hole by performing a series of operations in which the first component is caused to be moved closer to the provisional center position from a first side in a first direction passing the provisional center position and is caused to be lowered toward the second component, and by performing a similar series of operations from a second side in thesame direction; and a st
