Parameter identification techniques are particularly attractive to determine the inertial parameters of robot manipulators and manipulated payloads. These parameters are particularly needed in implementation of a model-based controller for robot manipulators. In this paper, the inertial parameters of a manipulated rigid-body object have been estimated. The Newton-Euler equations will be employe...
as polysemy is encountered frequently in english as foreign language. fl learners’ ability to disambiguate polysemous verbs becomes critical to their comprehension in the target language. this thesis, accordingly, investigated how iranian efl learners achieved comprehension of english polysemous verbs by using three different types of cues: (1) elaborated context, (2) semantic frames, and (...
This paper proposes the distributed impedance approach as a new formulation of multiple robot systems control. In this approach, each cooperating manipu-lator is provided with its own independant impedance controller. In addition, along selected degrees of freedom , force control is achieved through an external loop, in order to improve control of the object's internal loading. Extensive stabil...
the presence of an unknown environment, have been proposed [8]. The Object Impedance Control (OIC), an extension of impedance control, has been developed for multiple robotic arms manipulating a common object [9]. The OIC enforces a designated impedance not of an individual manipulator endpoint, but of the manipulated object itself. A combination of feedforward and feedback controls is employed...

within communicative, interactive, and learner-centered framework of language teaching and learning, students need to learn four skills of listening, speaking, reading, and writing for their educational success. but of all the language skills, reading enjoys a paramount significance in so many second or foreign language academic contexts. in spite of its importance, language learners still have...
in this study, a novel variable impedance control for a lower-limb rehabilitation robotic system using voltage control strategy is presented. the majority of existing control approaches are based on control torque strategy, which require the knowledge of robot dynamics as well as dynamic of patients. this requires the controller to overcome complex problems such as uncertainties and nonlinearit...
Impedance control provides a convenient framework for designing control algorithms for robotic applications that involve interaction with the environment. Passive impedance control was utilized in the early days of robotic applications, when the peg-in-hole type of tasks were performed using remote center compliance. Active impedance control using digital measurements of contact forces for debu...
