modeling and wrench feasible workspace analysis of a spatial cable suspended robots is presented. a six-cable spatial cable robot is used the same as stewart robots. due to slow motion of the robot we suppose the motion as pseudostatic and kinetostatic modeling is performed. various workspaces are defined and the results of simulation are presented on the basis of various workspaces and applied...

– one of the important applications of robots is in material handling and transport of various shaped objects. in cases where an object cannot be directly grasped by the robot gripper, and must be carried by a hook, it may be subject to undesirable swings during transport. this paper presents an analytical method for minimizing the oscillation of a suspended object during transport. this method...

System evaluations have been conducted in robotics and human-robot interaction for many years. These evaluations usually take place after a robot system has been designed and built as a way to validate the completed system. However, by performing evaluation only at the end of the development cycle, we lose opportunities to create systems with even better performance. Taking inspiration from hum...

We examine the scalability of multi-robot algorithms. In particular, we attempt to capture the idea that the less coordination a multi-robot system requires, the better it should scale to large numbers of robots. To that end, we introduce a notion of communication complexity of multi-robot (or more generally, distributed control) systems as a surrogate for coordination. We describe a formalism,...

This paper presents an approach for multi-robot coordination based both on coordinated navigation and task allocation method. An ad hoc agent based architecture is defined in order to implement the robot control system in both simulation and real applications. The coordination of the multi-robot system is based on agent interaction and negotiation, and a communication infrastructure based on op...

Robots have become significantly more powerful and intelligent over the last decade, and are moving in to more service oriented roles. As a result robots will more often be used by people with minimal technical skills and so there is a need for easier to use and more flexible programming systems. This paper reviews the current state of the art in robot programming systems. A distinction is made...

Membrane computing is an interdisciplinary research field focused on new computational models, also known as P systems, inspired by the compartmental model of the cell and the membrane transport mechanisms. Numerical P systems are a type of P systems introduced by Gh. Păun in 2006 for possible applications in economics. Recently, an extension of numerical P systems, enzymatic numerical P system...

due to their advantages, omni-directional mobile robots have found many applications especially in robotic soccer competitions. however, omni directional navigation system, omni-vision system and kicking mechanism in such mobile robots have not ever been combined. this situation brings the idea of a robot with no head direction into existence, a comprehensive omni directional mobile robot. such...

Object-oriented frameworks are a promising new technology to improve software quality and reduce development costs. In contemporary software development frameworks play an increasingly important role. Subject of our paper is an object-oriented ready-to-use framework for robot control systems. benefits are the fast software development, the better quality of software and the reduction of costs. ...
