The signal output terminals of the infrared sensors 10 on the left and right sides are connected to one input terminal of a comparator 23, the other input terminal of the comparator 23 is connected to an auxiliary power source, and the output terminal of the comparator is connected to the negative electrode of the power source through the coil of a relay 24. One end of a normally open contact of the relay 24 is connected to the output end of the comparator 23, and the other end of the coil of the relay 24 is connected to the negative electrode of the power supply through the switch 25. The signal A end, the signal B end, the signal C end and the signal D end are respectively connected to a power supply through four normally open contacts of the relay. The signal A end sends full-speed signals of the two motors to the controller Aa end, the signal B end sends left-direction signals of the two motors to the controller Ab end, the signal C end sends full-speed signals of the two motors to the controller Ba end, and the signal D end sends right-direction signals of the two motors to the controller Bb end. The infrared sensors 10 on the left and right sides monitor the intensity of the infrared rays fed back in real time. When the intensity of the infrared sensor 10 at one side is detected to meet the set intensity value, the comparator 23 judges that the left sensor is close to the bookshelf 5, the signal output end of the infrared sensor 10 sends out a signal, after the coil of the relay receives the signal, the normally open contact of the relay is closed, and a high-level signal with the duration of 1 second is output at intervals of 1 second through the signal B end or the signal D end, so that the current rotating speed and direction of the left motor and the current rotating speed and direction of the right motor are fed back to the controller. When the controller feeds back the control command to the motors, and the intensity detected by the left sensor and the right sensor is consistent, the normally open contact of the relay is closed, and full-speed signals of the two motors are fed back to the controller through the signal A end and the signal C end.

The signal E end sends a full-speed signal of the outer motor to the controller Ca end, the signal F end sends a half-speed signal of the inner motor to the controller Cb end, the signal G end sends a full-speed signal of the inner motor to the controller Da end, and the signal H end sends a half-speed signal of the outer motor to the controller Db end. The distance sensor 22 monitors the intensity of the infrared rays fed back in real time. When the strength does not meet the set strength value, the comparator 23 judges that the sensor is far away from the bookshelf 5, a signal is sent out from the signal output end of the distance sensor 22, after the coil of the relay receives the signal, the normally open contact of the relay is closed, and then a high-level signal with the duration of 1 second is output by taking the signal F end or the signal H end as an interval of 1 second so as to feed back the current half-speed signal direction of the outer motor or the inner motor to the controller, thereby realizing gesture adjustment in the left-right movement process and avoiding falling from the bookshelf 5. When the controller feeds back the control command to the motors, and the intensity detected by the left sensor and the right sensor is consistent, the normally open contact of the relay is closed, and full-speed signals of the two motors are fed back to the controller through the signal E end and the signal G end.
