Setting method using teaching operation

A setting method of setting a target operating pose of a robot and a target operation position of a transportation device in a three-dimensional space by a manual teaching operation in a robot system, the robot system including:

• the robot having an acting part acting on a target object;
• the transportation device having the robot mounted thereon and moving to a set operation position;
• and a controller controlling operations of the robot and transportation device, the three-dimensional space being formed by a first axis, a second axis, and a third axis, the first axis and the second axis being orthogonal to each other in a horizontal plane, the third axis extending vertically and being orthogonal to the first axis and the second axis,
• the setting method comprising in sequence:
• a first step of moving the transportation device to a position to be set as a predetermined operation position in a plane formed by the first axis and the second axis, and then storing the operation position as a provisional operation position;
• a second step of operating the robot in the three-dimensional space with the transportation device stopped at the operation position to bring the robot into a predetermined operating pose, and then storing the operating pose as a provisional operating pose;
• a third step of moving the acting part along the first axis and along the second axis by changing a pose of the robot with the transportation device at the provisional operation position and the robot in the provisional operating pose to confirm whether movable amounts in the first axis direction and the second axis direction of the acting part exceed previously obtained positioning error amounts in the first axis and the second axis of the transportation device;
• and
• a fourth step of, when both of the movable amounts in the first axis direction and the second axis direction of the acting part exceed the positioning error amounts in the first axis and the second axis of the transportation device, storing the provisional operation position as the target operation position and storing the provisional operating pose as the target operating pose.
