In this work, we present a novel concept in the area of optimal grasp synthesis, confronting both geometric and mechanical constraints. Initializing from a locally optimal force distribution on some predefined feasible contact points, our method improves gradually the grasp quality avoiding simultaneously singularities and mechanical limitations.A Learn by Demonstration Approach for Closed-Loop, Robust, Anthropomorphic Grasp Planning. Minas V. Liarokapis, Charalampos P. Bechlioulis, George I.In this letter, we consider the problem of prescribed time scale robot navigation. Initially, we treat the problem for a special class of configuration spaces, namely, sphere worlds, proposing a time-varying control scheme that drives the robot from any initial condition to an arbitrary neighborhood of any desired configuration within a predetermined time span, …May 22, 2019 · In this paper, we propose a visual servoing scheme that imposes predefined performance specifications on the image feature coordinate errors and satisfies the visibility constraints that inherently arise owing to the camera's limited field of view, despite the inevitable calibration and depth measurement errors. Its efficiency is demonstrated via comparative experimental and simulation studies. Charalampos P. Bechlioulis.
