A robot system includes a robot main body, memory part configured to store information for causing robot main body to perform given operation, as saved operational information, motion controller configured to control operation of robot main body by using saved operational information as automatic operational information for causing robot main body to operate, and an operation correcting device configured to generate, by being operated, manipulating information for correcting operation of robot main body during operation. Motion controller controls robot main body to perform an operation corrected from operation related to automatic operational information in response to a reception of the manipulating information while robot main body is operating by using automatic operational information. Memory part is configured to be storable of corrected operational information for causing robot main body to perform corrected operation as saved operational information, when robot main body performs corrected operation.
