The limited availability of energy resources in space implementations requires the use of low-power and low-capacity actuators in satellite manipulators. This constraint makes it necessary to employ the manipulator structure to be lightweight in order to maintain task performance; however, the resulting increase in str...

Residual vibration of industrial manipulators can limit positioning efficiency and dynamic accuracy during high-speed motion. This study develops an integrated vibration-suppression framework for a rigid-link manipulator with flexible-joint dynamics. A controller-oriented rigid–flexible model with lumped disturbances i...

Cable-driven manipulators have garnered increasing attention in robotics owing to their lightweight structure, flexible transmission mechanisms, and large operational workspace. However, the strong nonlinear dynamics, parameter coupling, and external disturbances inherent in cable-driven systems pose significant challe...

Abstract This paper addresses the robust trajectory tracking problem of an Unmanned Aerial Vehicle (UAV) equipped with a 2-DOF manipulator, which is designed for fast aerial manipulation of varying payloads. To overcome the high computational cost and adaptability limitations of traditional model-based controllers, thi...

High-performance positioning of multi-degree-of-freedom (multi-DOF) hydraulic manipulators in tunnel environments remains challenging. A major reason is the need to reconcile operational efficiency with motion smoothness in the presence of highly nonlinear hydraulic dynamics and lumped disturbances. To address these ch...
