About
Alexander R. K. Towlson is a leading researcher in non-destructive evaluation and robotic sensing, specializing in ultrasonic imaging for infrastructure inspection. His work focuses on developing advanced air-coupled ultrasonic arrays and autonomous robotic systems for assessing the internal geometry and surface condition of buried pipes and pipelines. Towlson’s major contributions include pioneering multi-view ultrasonic imaging solutions that enable high-resolution, real-time characterization of pipe interiors without direct contact, overcoming limitations of traditional methods. His 2024 paper on air-coupled ultrasonic arrays for pipe assessment, which has garnered 6 citations, demonstrates the use of a 64-transducer array mounted on a crawler robot, controlled by a Raspberry Pi, to extract critical structural data. In 2025, he advanced this field with a dual-resolution acoustic-sensing robot for autonomous in-pipe inspection (1 citation) and a multi-view imaging approach for buried sewer pipes (2 citations). Towlson’s work is notable for integrating cost-effective, open-source hardware with sophisticated signal processing, making high-fidelity pipe inspection accessible for aging infrastructure management. His research directly addresses global challenges in water and wastewater system maintenance, positioning him as an innovator in robotic sensing and ultrasonic non-destructive testing.
