DuckyDog: An Erect Amphibious Robot with Variable‐Stiffness Legs and Passive Fins
Advanced Intelligent Systems, Volume 7, Issue 7, July 2025.DuckyDog, a quadruped amphibious robot using erect posture, is proposed with dog‐inspired tendon‐driven compliant legs for walking and paddling, a duck‐inspired body for buoyancy, and passive fins to increase propulsion. It achieves maximum speeds of 0.4 body lengths per second on land and 0.3 on water, demonstrating the ability to navigate in complex ...

Detent Force Analysis in Permanent Magnet Linear Synchronous Motor Considering Longitudinal End Effects [PDF]
Journal of international Conference on Electrical Machines and Systems, 2013 This paper presents a uniform analytical model by energy method and Fourier series expansion to analyze detent force in uneven magnetic field for permanent magnet linear synchronous motor (PMLSM). The model reveals that detent force in long-primary type is mainly influenced by non-ideal distribution of permanent magnet magnetic motive force, while ...

Archaeology in Oceania, Volume 60, Issue 2, Page 156-175, July 2025.ABSTRACT This paper examines ring trees—a type of culturally modified tree, intentionally created by Australian First Nations Aboriginal peoples by manipulating tree growth to form permanent loops (rings) within the structure. Historically, this site type has been underrepresented and underappreciated by academics and archaeologists.
