About

Zhiwei Mao is a leading researcher in intelligent welding robotics, with a primary focus on automated seam tracking and mobile robotic systems for large-scale industrial fabrication. His work addresses critical challenges in shipbuilding and spherical tank welding, where precision and mobility are paramount. Mao’s most influential contribution is the development of a mobile welding robot system that integrates a rotating arc sensor for real-time seam tracking, combined with an ultrasonic sensor for obstacle avoidance. This system, detailed in his 2010 paper (10 citations), enables autonomous, large fillet welding with enhanced accuracy. In his earlier foundational work (2007, 8 citations), Mao tackled the complex problem of curved seam tracking by designing a novel controller based on integral backstepping time-varying state feedback. This mathematically rigorous approach not only ensured system stability but also provided a robust solution for non-linear welding paths. With over 18 citations across his key publications, Mao’s research has significantly advanced the practical deployment of autonomous welding robots in heavy industry, bridging the gap between theoretical control systems and real-world manufacturing needs.
