In this paper a flexible robot system for assembly operations in a semi structured environment is proposed. The system uses a moveable robot equipped with an arbitrarily mounted 3D camera and a 2D camera on the robot gripper for accurate object detection. The system is developed based on the Robot Operating System (ROS) and uses the state of the art trajectory planner MoveIt for collision free robot...
A case is made for the following claims. Higher animals have evolved the ability to make predictions because it increases their chance of survival. The basic steps in the prediction process are - registration of the internal spatial model with the world, initialization of salient objects (including actors) within the world model, projection of actor behaviors and movements through time, and assessment...
Engineering self-adaptive service-based applications significantly challenges the role of requirements engineering (RE). Such systems need to cope with the evolving requirements at runtime by monitoring the changes in users' preferences and in the environment, evaluating the changes and enacting a suitable behavior ensuring an acceptable level of quality for their users. This calls for continuous...
Requirements are sensitive to the context in which the system-to-be must operate. Where such context is well understood and is static or evolves slowly, existing RE techniques can be made to work well. Increasingly, however, development projects are being challenged to build systems to operate in contexts that are volatile over short periods in ways that are imperfectly understood. Such systems need...
We deal with self-adaptive systems where each local entity has autonomy in the way of strong coactivity with others entities to make the emergence of a coherent general state of the complete system. The paper focus on the architecture of a self adaptive system based on massive multi agent systems. The system allows the monitoring and on-line restructuring thanks to ontology. It is dedicated to a complex...
