Design Philosophy and Mechanical Features
The robot features a modular architecture from 2mm-thick 6061-T6 aluminum, emphasizing high strength-to-weight ratio and corrosion resistance. It is designed for fully onboard, real-time autonomy within 150-200 mm pipelines without hardware reconfiguration.
Articulated joints with high-torque servo actuators allow ±45° rotation for navigating T-junctions and elbows. Each wheel is 85mm in diameter with a rubberized tread, optimizing traction and shock absorption.
Integrated Sensor Suite and Autonomous Control
The system integrates a Raspberry Pi 4 for high-level processing (image acquisition, real-time video streaming, multi-sensor data fusion) and an Arduino Mega 2560 for low-level control (motor speed, sensor polling).
Sensors include an 8 MP Raspberry Pi camera, HC-SR04 ultrasonic sensors (front and flanks for obstacle detection up to 30 cm with 1.8 cm error), and an MQ-2 gas sensor (detects flammable gases at 200 ppm). Navigation uses dead-reckoning with ultrasonic-based obstacle avoidance.
Experimental Validation and Key Results
The robot demonstrated a maximum speed of 0.25 m/s, obstacle detection accuracy of 91.2% (PVC) and 89.5% (steel), climb capability of up to 45°, and battery endurance of approximately 80 min. Tests were conducted in 150 mm PVC and steel pipes with various obstacles and inclines (15°, 30°, 45°).
Video transmission latency was 0.82 ± 0.07 s in PVC and 1.12 ± 0.15 s in steel, within acceptable real-time limits. The system proved robust against varying surface conditions, including oily and corroded environments.
Comparative Advantage Over Existing Systems
The proposed crawler robot offers significant improvements over conventional inspection systems:
- Adaptability: Operates across 150-200 mm diameters without mechanical reconfiguration, unlike many fixed-diameter systems.
- Autonomy: Features onboard, real-time obstacle detection and navigation decisions, reducing reliance on human operators.
- Sensing Integration: Fuses visual, ultrasonic, and gas sensing data at the edge for comprehensive defect detection.
- Cost-Effectiveness: Prototype build cost of approximately USD 1,200, significantly lower than commercial systems.
Strategic Roadmap for Industrial Deployment
Future work includes field deployment trials, data collection for AI model training, and communication system enhancements (low-frequency RF, hybrid tethering). Mid-term goals involve AI-based defect classification, onboard real-time inference, and expanded sensor suites (LiDAR/structured light for 3D mapping).
Long-term plans aim for SLAM integration, multi-robot coordination, digital twin connectivity, and full industrial deployment with certification and compliance to standards like API 1163 and ASME B31.8 S.
