The present invention discloses a control method of a mowing robot. With the control method adopted, the technical problem of inflexibility of the movement of a mowing robot in the prior art can be solved. The mowing robot comprises a main control module and a walking mechanism; the main control module is connected with a gyroscope sensor for collecting the angular velocity of the movement of the mowing robot; and the main control module receives the angular velocity data of the gyro sensor in real time and calculates the angle information of the current movement of the mowing robot. The control method of the mowing robot includes steering direction control and steering angle control, wherein the steering direction control is used for controlling the rotation direction of the robot, and the steering angle control is used for controlling the steering angle of the robot after steering is completed; and the main control module obtains actual angle data according to the angular velocity data fed back by the gyroscope sensor and compares the actual angle data with predetermined angle data so as to control the steering angle of the robot.
