Human-centred Assembly: A Case Study for an Anthropocentric Cyber-physical System

This paper presents an integrated cyber-physical system for remote accessibility and controllability of factory equipment, e.g. CNC machines and robots. It is enabled by combining 3D models, sensor data and camera images in real-time. The aim of this research is to significantly reduce network traffic for much improved accessibility and controllability of any cyber-physical systems over the Internet. The ultimate goal is to build cloud-based services of monitoring, process planning, machining and assembly in decentralised environment. This paper covers the basis of the approach, system architecture and implementation, and a case study of remote control of a robotic assembly cell. Compared with camera-based systems, our approach consumes less than 1% of its network bandwidth, feasible and practical as a future cloud-based solution.

Control Part

In this paper, we study selected aspects of determinism in the control part of a cyber-physical system (CPS) that is specified by a Petri net-based model. In particular, the control interpreted Petri nets (CIPNs) are applied, which are an extension of the ordinary Petri nets, supplemented by signals (related to sensors and actuators) that permit communication with the environment. The notions of weak and strong determinism in a system described by a CIPN are introduced in the paper. The proposed concepts are supported by formal definitions and theorems. Moreover, a novel modelling methodology for a deterministic system specified by a CIPN is proposed. The presented solutions are illustrated by a case study example of a real-life cyber-physical system. Finally, the results of experimental verification of the proposed determinism-based techniques are demonstrated and discussed.

Environment Perception

Cyber-physical system (CPS) is a multiple system where physical world operations are monitored and controlled by communication and computing components. This paper focuses on the framework, design and simulation of a CPS for public security applications. A framework of the CPS is presented, and its compositions are analyzed in detail. To meet the requirements of cyber-physical control, the design features of environment perception and communication are investigated. An improved task allocation method and a hybrid approach for path planning are introduced for robots coordination and optimization. Finally, the CPS is demonstrated with a case study in a public security scenario, where robots equipped with sensors cooperate with each other to extinguish fires arising due to a disaster. The simulation experiments are conducted to show the feasibility of such system.
