Bio-Inspired and Neuro-Inspired systems or circuits are a relatively novel approaches to solve real problems by mimicking the biology in its efficient solutions. robotic also tries to mimic the biology and more particularly the human body structure and efficiency of the muscles, bones, articulations, etc. Address- Event- Representation (AER) is a communication protocol for transferring asynchronous events between VLSI chips, originally developed for neuro-inspired processing systems (for example, image processing). Such systems may consist of a complicated hierarchical structure with many chips that transmit data among them in real time, while performing some processing (for example, convolutions). The information transmitted is a sequence of spikes coded using high speed digital buses. These multi-layer and multi-chip AER systems perform actually not only image processing, but also audio processing, filtering, learning, locomotion, etc. This paper present an AER interface for controlling an anthropomorphic robotic hand with a neuro-inspired system.

Efforts are underway to make it possible for a single operator to effectively control multiple robots. In these high workload situations, many questions arise including how many robots should be in the team (Fan-out), what level of autonomy should the robots have, and when should this level of autonomy change (i.e., dynamic autonomy). We propose that a set of metric classes should be identified that can adequately answer these questions. Toward this end, we present a potential set of metric classes for human-robot teams consisting of a single human operator and multiple robots. To test the usefulness and appropriateness of this set of metric classes, we conducted a user study with simulated robots. Using the data obtained from this study, we explore the ability of this set of metric classes to answer these questions.

This research is concern with a novel architecture to control via the Internet multiple autonomous robotic devices that must complete a series of tasks collaboratively. Remote users need real time feedback on system operation and this should be platform independent and consume minimal bandwidth and processing power. This paper presents an online virtual feedback generator that deliver a generic user interface suitable for wide range of applications of pervasive computing technologies.

The paper deals with a problem of a description and analysis of fault trees with time dependencies, constructed for real-time systems to show possible ways leading to a hazard. Both the description and analysis are made with the duration temporal logic formalism - Duration Calculus (DC). It is the first time, when fault trees, containing the temporal gates, proposed by Magott and Skrobanek, got formally described with the DC logic (preserving all their properties for each gate type and for the whole structure) and became possible to be formally deductively analyzed (the latter part still need same work though).

E-mail system has been designed once to be one of the most reliable internet services. All possible steps were taken in the protocol to assure either a positive delivery of e-mail or the return of an error message. This is now circumvented in many ways by various antispam techniques and the SMTP protocol cannot be considered reliable anymore. The paper discusses some of the current SMTP protocol modifications that are considered harmful and proposes a way for maintaining the reliability of the protocol while increasing the immunity to spam.

Effective communication with a mobile robot using speech is a difficult problem even when you can control the auditory scene. robot ego-noise, echoes, and human interference are all common sources of decreased intelligibility. In real-world environments, however, these common problems are supplemented with many different types of background noise sources. For instance, military scenarios might be punctuated by high decibel plane noise and bursts from weaponry that mask parts of the speech output from the robot. Even in non-military settings, however, fans, computers, alarms, and transportation noise can cause enough interference that they might render a traditional speech interface unintelligible. In this work, we seek to overcome these problems by applying robotic advantages of sensing and mobility to a text-to-speech interface. Using perspective taking skills to predict how the human user is being affected by new sound sources, a robot can adjust its speaking patterns and/or reposition itself within the environment to limit the negative impact on intelligibility, making a speech interface easier to use.

This paper describes our progress in the development of a behavior-based, stimulus-response robotcontrol software architecture that is expressly designed to program and execute interactive tasks, including assembly, multi-robot collaborative manipulation, and exploration. The system has been designed to assure stability and safety while maintaining flexibility and achieving expert performance. The architecture incorporates a reactive controller as a behavior server, and applications are written as client programs that can operate either locally or across a network. This organization has been demonstrated to be sufficiently open to support teleoperation tasks as well as human-guided supervisory control and full autonomous functionality.

This paper presents a new system architecture of the Competitive robot over the Internet based on C/S, realizes a human-robots interactive game over the Internet, does some researches on its characteristics, and describes the architecture, software programming and the key technology of each parts in details. The whole system adopts the technology of Windows operation system, VC++, and Winsock network programming. The distributed simulation system of robot Soccer over the Internet is based on HLA.. The delay of network transmission has been analyzed and tested. The competitions that rely on the regulations have been finished. The results show that this system can simulate the whole process of soccer competitions of human being, and meet the demands of stability and reliability.

In this work, the leader-follower control problem is solved by using Full-state linearization via dynamic feedback. This approach has certain advantages over the well known input-output linearization such as no relative point selection, simple extension to n-robots formation and representation of all dynamics incase of Car-Like robot model. Simulation results verify the validity and limitation of these controllers by Matlab. The new 3-D robot simulator Gazebo with robot server Player is also used to verify the results.

robots are considered as ideal multi-domain or mechatronic systems. A biped or two-legged walking robot incorporates robust mechanical design, efficient electronics and intelligent motion control techniques to balance itself while standing and walking. Location of center of gravity (COG) of the robot is the key to its stability. Research studies [1] have been carried out to develop mathematical models for robot kinematics, motion and stability. This paper presents an alternative approach for developing state-space equations and motion profile simulations of kinematic sections of a biped robot through Bond-Graph modeling and simulation technique which by design is more suitable for modeling and simulation of multi-domain systems than any other contemporary modeling and simulation approach.
