[0002] In some working environments that are not suitable for workers to enter directly or stay for a long time, automated robots have significant advantages in passing and survival compared to manual labor.

When turning left or right, the traction ropes on the left and right sides are controlled to be released and retracted by their respective traction motors 31; when pitching up and down, the upper and lower traction ropes are controlled to be released and retracted by their respective traction motors 31; a drive motor 32 is provided inside the end box 12, and the drive motor 32 is linked to a drive wheel 321, and the drive motor 32 is linked to the drive wheel 321 through a reducer 322. In this embodiment, the reducer 322 can be a planetary reducer; the drive wheels 321 of the front and rear end boxes 12 are jointly equipped with an outer track 4, and the inner surface of the outer track 4 is in sliding contact with the outer surface of the support part 1. In this embodiment, the drive wheel 321 includes track gears coaxially arranged on both sides of the end box 12, and the two sides of the outer track 4 are provided with gear holes 45 for the track gears. After the drive motor 32 is started, the gear holes 45 are driven to move by the track gears.

[0043] In this embodiment, the support portion 1 is provided with a T-shaped guide channel 13 on the outer surface along the long axis direction, and the inner surface of the peripheral crawler 4 is evenly provided with several T-shaped sliders 42 that are matched with the T-shaped guide channel 13. When in use, the T-shaped end of the T-shaped slider 42 can be translated according to the guide of the T-shaped guide channel 13. The peripheral crawler 4 is formed by several crawler modules 43 connected by rod end joint bearings 44. The crawler module 43 can be made of non-slip rubber material, which can reduce weight while increasing the buffering effect to avoid vibration of internal components. The T-shaped slider 42 is provided on the inner surface of the crawler module 43. Through the arrangement of the T-shaped slider 42 and the T-shaped guide channel 13 , so that the outer track 4 can fit the outer surface of the support part 1, increasing the integration effect of the device; the T-shaped guide channel 13 is arranged according to the middle of the long axis of the support part 1, and the width of the track module 43 is uniformly reduced from the middle to the two side ends; the width of the T-shaped slider 42 is uniformly reduced from the middle to the two side ends, which can effectively avoid mutual interference during twisting; the spine module 11 is evenly provided with rolling elements 14 on both sides of the T-shaped guide channel 13, and the rolling elements 14 are in contact with the inner surface of the outer track 4, reducing friction and reducing the wear of the outer track 4; the rolling elements 14 are rollers and / or balls, and the present embodiment is a cylindrical roller.

[0044] At least one end face of the end box 12 is equipped with a sensing detector 22. In this embodiment, the sensing detector 22 is equipped at the forward end of the variable spine single-track detection robot. The sensing detector 22 is at least one of an ultrasonic detector and an infrared sensor.

[0045] Also disclosed is a method for using the above-mentioned variable spine single-track detection robot, comprising the following steps:

[0046] 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 instruction via WiFi. First, through the API interface for processing remote instructions, 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 steering (api / robot / turn) instructions. Secondly, through the user web interface, the control instruction in the form of an HTTP request is sent 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 sensor detector 22 on the variable spine single-track detection robot collects status information and feeds it back to the server. The server then sends this information back to the user interface, allowing the user to monitor the status of the variable spine single-track detection robot in real time. To ensure communication security, the entire communication process can be encrypted using the SSL encryption protocol. In addition, error handling is required to address possible network delays or packet loss issues to ensure system stability and reliability. Because 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 Raspberry Pi's CSI interface) is wirelessly transmitted via WiFi to the control module 52 for processing.

[0047] S2, after receiving the image data through the combination of the data uploaded by the perception detector 22 and the binocular detection camera 21, the control module 52 uses the image processing library to process the environmental information, and 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 so, step S4 is executed.

[0048] In step S3, the control unit sends a PWM command to the motor driver module 53. The motor driver adopts the L298N model and is connected to the GPIO port of the Raspberry Pi. The output terminals OUT1 and OUT2 of the motor driver module 53 are respectively connected to the drive motors 32 at both ends. The drive motor 32 is powered on to rotate forward, and the variable spine single crawler detection robot continues to move forward.

[0049] S4: The ultrasonic and infrared sensors connected to the GPIO port of the control unit and the binocular terrain detection module are used to determine the distance to the obstacle and whether it is surmountable. The perception detector 22 uses the time difference between the emitted and received waves obtained by sound reflection to calculate the obstacle distance. The control unit determines whether the obstacle is short or tall based on the image information, obstacle information, and IMU data, and performs the corresponding obstacle avoidance action. If the obstacle height detected by the sensor is greater than a preset value (in this embodiment, the preset obstacle height value is 13 cm), the control unit determines that the obstacle is a high obstacle and performs an emergency obstacle avoidance action, that is, executing step S5. If the obstacle height is less than the preset value, executing step S6.

[0050] S5, using the binocular detection camera 21 and the perception detector 22 to determine whether there are obstacles on both sides of the insurmountable obstacle; if not, proceed to step S7; if so, proceed to step S8;

[0051] S6, the control unit sends a PWM instruction to the motor drive module 53, and by inputting pulses with different duty cycles into the traction motor 31, the traction motor 31 can be rotated to different angles, controlling the operation of the up and down pitch traction motor 31 and tightening the upper traction rope while loosening the lower traction rope, so that the variable spine single-track detection robot raises its head to a certain height. While the traction motor 31 adjusts the posture of the variable spine 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 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 single-track detection robot raises its head, the drive motor 32 can provide enough power for the variable spine 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 single-track detection robot returns to its normal posture and driving state;

[0052] S7, the control unit starts the traction motor 31 that controls the left and right turning angles, causing the spine module 11 to perform a lateral turning action; after crossing the high obstacle, the control unit resets the traction motor 31, and the variable-spine single-track detection robot returns to a normal posture and driving state;

[0053] S8, collect environmental information, the control unit uploads the obstacle picture via WiFi, and waits for the next instruction. At the same time, the program loops to judge the above steps.
