A robot system includes: a learning control unit configured to perform learning for calculating a learning correction amount for bringing a position of a control target portion toward a target position; a robot control unit configured to control the operation of the robot mechanism unit; a power spectrum calculating unit configured to calculate a power spectrum of a vibration data of the control target portion; a comparison unit configured to compare each power spectrum between at the time of the current learning and at the time of the immediately preceding learning; and a learning correction amount updating unit configured to adjust at least one of a phase and a gain of the learning correction amount used at the time of the current learning to set the adjusted learning correction amount as a new learning correction amount used at the time of next learning.
