Challenges in the Safety-Security Co-Assurance of Collaborative Industrial Robots

Abstract

The coordinated assurance of interrelated critical properties, such as system safety and cyber-security, is one of the toughest challenges in critical systems engineering. In this chapter, we summarise approaches to the coordinated assurance of safety and security. Then, we highlight the state of the art and recent challenges in human-robot collaboration in manufacturing both from a safety and security perspective. We conclude with a list of procedural and technological issues to be tackled in the coordinated assurance of collaborative industrial robots.3 Throughout this chapter we refer to cobots as robots, including their software and operational infrastructure, specifically designed for human-robot collaboration, although we accept that traditional robots may be used in collaborative ways when augmented with sufficient control and sensory systems.

Building Information Modeling (BIM) and Robotic Manufacturing Technological Interoperability in Construction – A Cyclic Systematic Literature Review

“…Based on this definition, programmable machines such as three-dimensional (3D) printers or laser cutters are not considered industrial robots since they are not multi-purpose. Instead, this definition is often linked to robotic arms, the most widely used robot for industrial automation [11,36]. Therefore, to narrow the breadth of this research, the present work is focused on the technological interoperability between BIM and RM using robotic arms.…”

Sustaining Security and Safety in ICT: A Quest for Terminology, Objectives, and Limits

“…Furthermore we see that safety and security are interconnected, in particular, that safe operation of equipment can only be guaranteed if that equipment is also secure. The field of study that combines these two aspects of risk assessment and engineering is dependability engineering [11], and important progress has been made regarding safety and security co-assurance for critical systems [17]. Particularly hard to assess in this context is the longterm survivability of systems, as Eder-Neuhauser et al point out with respect to the security of power grid infrastructure in [15]: "However, unlike consumer electronics, traditional power grid environments have a focus on long-term stability and plan for hardware life-spans of 10 years or more.…”

Analiza povezanosti robotizacije i tržišta rada Europske unije

“…Kolaborativni industrijski roboti ne samo da će povećati proizvodnost tvrtkama koje ih budu koristile nego će i smanjiti opterećenost radnika te povećati sigurnost na radu. Na taj će način ljudima i robotima biti omogućeno da dijele radni prostor i kombiniraju prednosti koje svatko od njih posjeduje (Gleirscher et al, 2020). Prema Craigu (2005), glavni razlog rasta broja novih industrijskih robota je pad cijene, ali i povećanje brzine, točnosti i fleksibilnosti te trend više cijene ljudskoga rada na tržištu.…”
