Robot skills that are needed to operate completely autonomously in a real complex scenario populated by humans are still beyond the capabilities that the current robotic technology offers. In spite of that, in a variety of assistant applications where human and robot are closely tied, mobile robots can perform an effective and valuable work if humans in the surroundings (or the assisted person) would be enabled to extend the robot abilities through skills either not supported by the machine or supported in a different and (maybe) less dependable manner. To achieve that, robot and human must closely interact and collaborate at all levels of the robotic architecture, including deliberation, control and execution. This paper proposes a new robotic architecture, called ACHRIN, which supports a strong integration of the human into the robotic system in order to improve the overall performance of the robot as well as its dependability. Our human-robot integration relies to a great extend on sharing symbolic concepts of the world (cognitive integration). ACHRIN has been implemented and tested in a real rehabilitation robot: a robotic wheelchair that provides mobility to impaired or elderly people.
In many multi-robot applications, ad hoc networks are formed for data communication, which enables effective decision making and results in significant energy and time saving. However, unnecessary large volumes of com...

In this paper necessary and sufficient conditions are presented for static output-feedback control of linear time-invariant systems using the H ∞ approach. H∞ design allows the derivation of a relaxed set of conditions which only requires the solution of two coupled matrix design equations. The output-feedback H∞ solution does not generally yield a well-defined saddle point for the zero sum differential game;conditions are given under which it does. This paper also proposes a new numerically efficient solution algorithm for the coupled design equations to determine the output-feedback gain. An initial stabilizing gain is not needed. AB aircraft design example is solved to illustrate the power of the proposed approach.
Despite several successful humanoid robot projects from both industry and academia, generic motion interfaces for higher-level applications are still absent. Direct robot driver access proves to be either very difficu...
