In-Pipe Inspection Micro Robot Adaptable to Changes in Pipe Diameter
Journal of Robotics and Mechatronics, 2003 In the development of a microrobot for inspecting the inside of pipes with an internal diameter of 1 to 3 inches, the author of this paper designed an in-pipe mobile mechanism adaptive to pipe diameter based on a snake robot and evaluated it theoretically and experimentally. The authors fabricated 2 robots of different size. The first, Prototype A, was

Research on Diaphragm Pump Fault Diagnosis Method Based on Res‐DCB‐Net
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Nonstationary pressure pulsation signals of diaphragm pumps contain strong background noise and coupled characteristics. This makes it challenging to extract incipient fault features and to decouple faults with similar physical mechanisms. To address these limitations, this paper proposes a spatiotemporal fault diagnosis model named Res‐DCB ...
