In this paper, a novel robust tracking control law is proposed for constrained robots under unknown stiffness environment. The stability and the robustness of the controller are proved using a Lyapunov-based approach where the relationship between the error dynamics of the robotic system and its energy is investigated. Finally, a 3DOF constrained robotic arm is used to prove the stability, the ...

the title of any written work is a name the author, or the critic, chooses for it. a book title is not important because it makes an identity for it or makes it different from other works, but it can indicate the quality and the importance in terms of structure as well.   the title is the first sign thet the reader confronts with, and the reader can recognize the works' content and its oth...

We have presented a theoretical extended version of dense coding protocol using entangled position state of two particles shared between two parties. A representation of Bell states and the required unitary operators are shown utilizing symmetric normalized Hadamard matrices. In addition, some explicit and conceivable forms for the unitary operators are presented by using some introduced basic ...
