dimensional synthesis of a parallel robot may be the initial stage of its design process, which is usually carried out based on a required workspace. since optimization of the links lengths of the robot for the workspace is usually done, the workspace computation process must be run numerous times. hence, importance of the efficiency of the algorithm and the cpu time of the workspace computatio...

Mankind has always strived to give life like qualities to its artifacts in an attempt to find substitutes for himself to carry out his orders and also to work in a hostile environment. The popular concept of a robot is of a machine that looks and works like a human being. The industry is moving from current state of automation to Robotization, to increase productivity and to deliver uniform qua...

based on dynamic modeling, robust trajectory tracking control of attitude and position of a spherical mobile robot is proposed. in this paper, the spherical robot is composed of a spherical shell and three independent rotors which act as the inner driver mechanism. owing to rolling without slipping assumption, the robot is subjected to two nonholonomic constraints. the state space representatio...

We have carried out developing a robot which can access internet. This robot, URC (Ubiquitous Robot Companion), is able to get information on the internet and to narrate it in human language. This work was due to the technology of Semantic Web Services, because this technology makes it possible to automate many tasks for machine. This paper presents experience gained during implementation of ro...

In this paper, we propose an application programming interface (API) for designing of a robot workspace. The interface is realized inside a SolidWorks computer aided design environment. Via API, the builder of the robot system can check if: a) the current robot mechanism can perform the desired work movements, b) the robot can avoid singularity, and c) the points of the robot trajectory are wit...

Once an individual has access to the Internet, there is a wide variety of different methods of communication and information exchange over the network, one of them is telepresence robot. This study presents a web framework for web conference system of intelligent telepresence robot. The robot is controlled using web conference system from Google App Engine, so the manager/supervisor at office/i...

This paper presents different possibilities of using mobile robots in education. Through the application of mobile mechatronic robotic system "Robotino" this paper shows the possibilities of developing interactive lectures and exercises in order to raise the quality of education and to provide new competencies for students. Application of robot as a real system supports strengthening specific a...

Robotic search and rescue is a challenging yet promising research area which has significant real-world application potentials. In this paper, a survey of multi-robot systems and how they can be implemented in search and rescue operations is presented. In particular, the problems of task allocation, communication, and human-robot interaction in multi-robot systems are explored.

In many robotic applications, the teaching of points in space is necessary to register the robot coordinate system with the one of the application. Robot-human interaction is awkward and dangerous for the human because of the possibly large size and power of the robot, so robot movements must be predictable and natural. We present a novel hybrid control algorithm which provides the needed preci...

⎯The study of robot animals based on brain-computer interface (BCI) technology is an important field in robots and neuroscience at present. In this paper, the development status at home and abroad of the motion control of robot based on BCI and principle of robot animals are introduced, then a new animals’ behavior control method by photostimulation is presented. At last, the application prospe...
