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