Processing method, program and robot system

A method of processing teaching data, the teaching data including position/posture information on an end effector attached to a robot, and including teaching points that form a moving route of the end effector in a time-series manner, the method comprising one or both of:

• a first processing in which a reference teaching point is extracted from the teaching points, the extracted reference teaching point having a difference between a direction vector from a position of a teaching point preceding the reference teaching point by a given interval to a position of the reference teaching point, and a direction vector from the position of the reference teaching point to a position of a teaching point succeeding the reference teaching point by a given interval, being equal to or more than a threshold;
• and
• a second processing in which the reference teaching point is extracted from the teaching points, the extracted reference teaching point having one of a difference between a posture at a teaching point preceding the reference teaching point by a given interval and a posture at the reference teaching point, and a difference between the posture at the reference teaching point and a posture of a teaching point succeeding the reference teaching point by a given interval being equal to or more than a threshold.
