Currently, zero-order sensors are commonly used as positioning feedback for the closed-loop control in robotics; thus, in order to expand robots’ control alternatives, other paths in sensing should be investigated more deeply. Conditions under which the n -th order sensor output can be used to control k -DoF serial robot arms are formally studied in this work. In obtaining the mentioned control conditions, the Pickard-Lindeloff theorem has been used to prove the existence and uniqueness of the robot’s mathematical model solution with n order sensory systems included. To verify that the given conditions and claims guarantee controllability for both continuous-based and variable structure-based systems, two types of control strategies are used in obtaining simulation results: the conventional PID control and a second-order Sliding Mode control.

Martin Geiger & Antoine Pécoud (eds.), Disciplining the Transnational Mobility of People, Palgrave Macmillan, 2013, 271 pp., (ISBN 978-1-137-26306-3).In the last decades a very diverse range of initiatives have been undertaken in order to intensify and diversify the ways human mobility is managed and restricted. This trend towards a ‘diversification’ of the migration control strategies stems from the increased awareness by the nation-states of the profoundly controversial nature of the migration management enterprise because of its political, economic, social and moral implications.
