[0022] Also disclosed is a method for using the above-mentioned variable spine single-track detection robot, comprising the following steps: S1, after the user establishes communication with the above-mentioned variable spine single-track detection robot, the user remotely sends the variable spine single-track detection robot automatic cruise mode control command through WiFi. First, through the API interface for processing remote commands, this interface runs on the Raspberry Pi and is implemented through the Flask framework. The API interface defines the endpoints for starting (api / robot / start) and stopping (api / robot / stop) the variable spine single-track detection robot, as well as the endpoint for sending turning (api / robot / turn) instructions. Secondly, through the user Web interface, send control instructions in the form of HTTP requests to the API interface of the variable spine single-track detection robot. Finally, after receiving the request, the interface parses the instruction and sends a PWM signal to the L298N motor driver module 53 through the GPIO port according to the instruction content to control the speed and direction of the motor, so that the variable spine single-track detection robot performs a cruise action. At the same time, the perception detector 22 on the variable spine single track detection robot will collect status information and feed it back to the server, and the server will send this information back to the user interface so that the user can monitor the status of the variable spine single track detection robot in real time; in order to ensure the security of communication, the entire communication process can be encrypted using the SSL encryption protocol; in addition, error handling is required to deal with possible network delays or packet loss problems to ensure the stability and reliability of the system. Since the Raspberry Pi 5 is equipped with an ARM chip-based image processing, the data detected by the binocular detection camera 21 (connected to the CSI interface of the Raspberry Pi) is wirelessly transmitted to the control module 52 for processing via WiFi; S2, after receiving the image data, the control module 52 combines the data uploaded by the perception detector 22 and the binocular detection camera 21, and uses the image processing library to process the environmental information. The control unit determines the obstacle distance and sets the obstacle avoidance threshold. In this embodiment, the obstacle avoidance threshold is set to 10 cm. When the obstacle distance is less than the preset braking distance of 10 cm, emergency braking is performed; by traversing the point cloud array, the depth information of each point is judged. If the depth is less than the preset depth value of 10 cm, the obstacle information array is updated, and the control unit processes the data and determines whether there is an obstacle ahead. If not, step S3 is executed. If yes, step S4 is executed. S3, the control unit sends a PWM command to the motor drive module 53. The motor drive adopts the L298N model and is connected to the GPIO port of the Raspberry Pi. The output terminals OUT1 and OUT2 of the motor drive module 53 are respectively connected to the drive motors 32 at both ends. The drive motor 32 is powered on and rotates forward, and the variable spine single crawler detection robot continues to move forward. S4, through the ultrasonic and infrared sensors and binocular terrain detection module connected to the GPIO port of the control unit, to determine the distance of the obstacle and whether it can be climbed over, the perception detector 22 uses the reflection of sound to obtain the time difference between the emitted and received waves to calculate the distance of the obstacle, and the control unit determines whether the obstacle is a short obstacle or a high obstacle based on the image information, obstacle information and IMU data, and performs corresponding obstacle avoidance behavior; if the obstacle height detected by the sensor is greater than the preset value, in this embodiment, the preset value of the obstacle height is 13cm, the control unit determines that the obstacle is a high obstacle, and performs an emergency obstacle avoidance action, that is, executes step S5, if the obstacle height is less than the preset value, then executes step S6; S5, determining whether there are obstacles on both sides of the insurmountable obstacle through the binocular detection camera 21 and the perception detector 22; if not, executing step S7, and if so, executing step S8; S6, the control unit sends a PWM instruction to the motor drive module 53, and by inputting pulses with different duty cycles to the traction motor 31, the traction motor 31 can be rotated to different angles, and the up and down pitch traction motor 31 can be controlled to operate, and the upper traction rope is tightened while the lower traction rope is loosened, so that the variable spine type single track detection robot raises its head to a certain height. While the traction motor 31 adjusts the posture of the variable spine type single track detection robot, the control unit sends a PWM signal to the DC motor to control the speed and direction of the motor. The PWM signal of the motor determines the speed of the motor, thereby controlling the moving speed of the variable spine type single track detection robot. The control unit needs to coordinate the actions of the traction motor 31 and the drive motor 32 to ensure that while the variable spine type single track detection robot raises its head, the drive motor 32 can provide sufficient power for the variable spine type single track detection robot to cross the obstacle. Once the obstacle is crossed, the control unit will send a new PWM signal to rotate the traction motor 31 back to its original position, tighten the traction rope, and the variable spine type single track detection robot returns to its normal posture and driving state; S7, the control unit starts the traction motor 31 that controls the left and right turning angles, so that the spine module 11 performs a lateral turning action; after crossing the high obstacle, the control unit resets the traction motor 31, and the variable spine single crawler detection robot returns to a normal posture and driving state; S8, collect environmental information, and the control unit uploads obstacle pictures via WiFi, waiting for the next instruction. At the same time, the program loops to judge the above steps.
