Electromagnetically Adhering and Self‐Inductive Sensing Claw for Continuum Climbing Robots: Design, Control, and Applications

Advanced Intelligent Systems, EarlyView.
To argue the applicability of continuum wall‐climbing robots in the nuclear industry, an electromagnetic adhering and self‐inductive sensing integrated claw is developed. The flexible claw realizes an integrated design of the physical structure and excitation circuit. An automatic contact strategy based on fuzzy controller is established, which enables

Leakage of Metallic Ball Seat Valves with Anisotropic Surfaces

Chemical Engineering &Technology, Volume 46, Issue 1, Page 102-109, January 2023., 2023
A better understanding of the physics behind metallic sealing can be applied to develop better metallic valves and static seals. Most importantly, the influence of surface roughness on the leak tightness must be investigated. Most technical surfaces of practical interest are highly anisotropic.

Monolithic Desktop Digital Fabrication of Autonomous Walking Robots

Advanced Intelligent Systems, EarlyView.
A soft, monolithic, air‐powered walking robot is designed for autonomous operation. Fabricated in a single step using a desktop (FFF) fused filament fabrication 3D printer, the robot requires no manual postassembly and becomes immediately operational with a constant‐pressure air supply.

Extreme High‐Speed Laser Material Application‐Coated Carbide‐Reinforced Control Plates and Conventional Lead‐Based Plates in Axial Piston Machines

Chemical Engineering &Technology, Volume 46, Issue 1, Page 110-117, January 2023., 2023
In hydraulic axial piston pumps, conventionally leaded brass is used right against steel. In order to renounce lead and find a lead‐free alternative, high‐speed laser material deposition is employed to apply a carbide‐reinforced anti‐wear coating. Based on the experiences of prior tests, it demonstrates that this coating also works in a state‐of‐the ...
