Control method, non-transitory storage medium, mover system, and parts mounting system

A control method for controlling a mover, the mover including a plurality of sensors and a plurality of drive wheels and configured to move on a traveling surface,

• a first sensor, selected from the plurality of sensors, being configured to, when a first longitudinal detection range overlaps with a trajectory provided on the traveling surface to guide the mover along the trajectory, detect a first position of the trajectory within the first longitudinal detection range,
• a second sensor, selected from the plurality of sensors and different from the first sensor, being configured to, when a second longitudinal detection range of the second sensor overlaps with the trajectory, detect a second position of the trajectory within the second longitudinal detection range,
• a third sensor, selected from the plurality of sensors and different from the second sensor, being configured to, when a third longitudinal detection range of the third sensor overlaps with the trajectory, detect a position of the trajectory within the third longitudinal detection range,
• the control method comprising:
• a first turning step including controlling the plurality of drive wheels to make the mover turn around the first position where the first longitudinal detection range overlaps with the trajectory until the second sensor senses, in a state where the first longitudinal detection range overlaps with the trajectory, a state where the trajectory is present at a first target position within the second longitudinal detection range;
• and
• a second turning step including controlling, after the first turning step has been performed, the plurality of drive wheels to make the mover turn around the first target position until the third sensor senses a state where the trajectory is present at a second target position within the third longitudinal detection range.
