摘要

Conventional methods are still labor-intensive, hazardous, and have limited coverage, even though reliable pipeline inspection is crucial for oil, gas, and water distribution networks, emphasize key challenges of pipeline inspection and automated navigation. Although robotic systems have advanced with mechanisms like helical motion and multi-joint telescopic designs, the problem of obtaining dependable adaptability in curved or varying-diameter pipes has not been solved. Additionally, there are still gaps in precise navigation and predictive decision-making under complicated pipeline conditions because of the limited integration of deep learning and computer vision into real-time autonomous platforms. To provide real-time navigation and predictive analysis, this work introduces an improved In-Pipe Inspection Robotic System (IPIRs) that integrates robotic simulation and deep learning. The system’s strong performance in navigation and visual object detection using YOLOv8 is demonstrated by its mean average accuracy (mAP (0.5)) of 97.9% and F1 score of 0.95. In addition to spatial scanning, the long short-term memory (LSTM) model analyzes temporal and group-action IMU data. The mean square error (MSE) of 0.00037 and mean absolute error (MAE) of 0.00581 test show that the model ensures accurate motor voltage prediction for smooth navigation and object detection in curved pipelines. The modular robot design, developed using the Robot Operating System (ROS) and evaluated using Gazebo and Rviz simulations, demonstrated its ability to automatically navigate and recognize objects in pipes with diameters ranging from 100 to 150 mm. The results demonstrate how the YOLOv8–LSTM architecture enhances inspection accuracy and enables predictive maintenance.
