• and
• a controller configured to control the arm to execute parameter setting operation for setting parameter by placing the first setting element at a plurality of positions, wherein
• the controller is configured to control the sensor to acquire first check data related to the target in a state in which the first setting element is placed at a setting check position in a first half of the setting operation or before executing the setting operation,
• the controller is configured to control the arm to execute a movement for placing the first setting element at the setting check position in a latter half of the setting operation or after executing the setting operation, and then controls the sensor to acquire second check data related to the target, and
• the controller is configured to judge whether or not there is a change in position of the first setting element or the second setting element based on the first check data and the second check data.
