Development of a novel 3D simulation modelling system for distributed manufacturing

This paper describes a novel 3D simulation modelling system for supporting our distributed machine design and control paradigm with respect to simulating and emulating machine behaviour on the Internet. The system has been designed and implemented using Java2D and Java3D. An easy assembly concept of drag-and-drop assembly has been realised and implemented by the introduction of new connection features (unified interface assembly features) between two assembly components (modules). The system comprises a hierarchical geometric modeller, a behavioural editor, and two assemblers. During modelling, designers can combine basic modelling primitives with general extrusions and integrate CAD geometric models into simulation models. Each simulation component (module) model can be visualised and animated in VRML browsers. It is reusable. This makes machine design re-configurable and flexible. A case study example is given to support our conclusions

Internet-based teleoperation: A case study - toward delay approximation and speed limit module

International audienceThis paper presents the internet-based remote control of mobile robot. To face unpredictable Internet delays and possible connection rupture, a direct teleoperation architecture with “Speed Limit Module” (SLM) and “Delay Approximator” (DA) is proposed. This direct control architecture guarantees the path error of the robot motion is restricted within the path error tolerance of the application. Experiment results show the effectiveness and applicability of this direct internet control architecture in the real internet environment

Exploration of the Internet Controlled \u27Rent-a-Factory\u27 Concept

There are several robots and other devices which can now be controlled over the Internet. It is possible that an expansion of this concept ultimately leading to an Internet controlled factory could assist Australia overcome the \u27tyranny\u27 both of distance and of small production volumes. This paper discusses initial work being performed to investigate the relevance and practicality of the Internet for remote factory operations. A review of current Internet controlled equipment is presented. New experimental work involving the development of a web based graphical interface enabling clear observation and control of an Adept-One robot over the World Wide Web is also described

The Penetration of Internet of Things in Robotics: Towards a Web of Robotic Things

As the Internet of Things (IoT) penetrates different domains and application areas, it has recently entered also the world of robotics. Robotics constitutes a modern and fast-evolving technology, increasingly being used in industrial, commercial and domestic settings. IoT, together with the Web of Things (WoT) could provide many benefits to robotic systems. Some of the benefits of IoT in robotics have been discussed in related work. This paper moves one step further, studying the actual current use of IoT in robotics, through various real-world examples encountered through a bibliographic research. The paper also examines the potential ofWoT, together with robotic systems, investigating which concepts, characteristics, architectures, hardware, software and communication methods of IoT are used in existing robotic systems, which sensors and actions are incorporated in IoT-based robots, as well as in which application areas. Finally, the current application of WoT in robotics is examined and discussed

Multi-Agent Systems

A multi-agent system (MAS) is a system composed of multiple interacting intelligent agents. Multi-agent systems can be used to solve problems which are difficult or impossible for an individual agent or monolithic system to solve. Agent systems are open and extensible systems that allow for the deployment of autonomous and proactive software components. Multi-agent systems have been brought up and used in several application domains
