The invention discloses a control method of a robot. The robot comprises a left wheel, a machine body, a right wheel, a left motor, a right motor, a front end pressure sensor, a balancing device and a back end pressure sensor, wherein the front end of the balancing device is arranged on the front end pressure sensor; and the back end of the balancing device is arranged on the back end pressure sensor. The control method of the robot comprises the steps of S1, judging in a certain time whether a signal is input or not, if the signal is input, starting a traveling mechanism, and if the signal is not input, enabling the robot to be in a power-saving standby mode; S2, judging whether an infrared remote control signal is input or not, if the infrared remote control signal is input, controlling the robot to move, and if the infrared remote control signal is not input, performing S3; S3, judging whether a voice control signal is input or not, if the voice control signal is input, controlling the robot to move, and if the voice control signal is not input, performing S4; S4, judging whether a distance measurement signal is smaller than a certain value or not, if the distance measurement signal is smaller than the certain value, performing judgment and rotating, and if the distance measurement signal is not smaller than the certain value, performing S5; and S5, judging whether a ground return signal is input or not, and if the ground return signal is input, braking the robot immediately.
