Implicit aspects of the psychosocial rehabilitation with a humanoid robot (2023)
Presentation / Conference Contribution

The paper presents an approach to understanding the emergent dynamics of human-robot interaction in the specific case of a humanoid robot taking the role of a co-therapist to the human therapist in psychosocial rehabilitation by focusing on the nonve...

The case for an intervention scale to design the balance of authority for robotic assistance (2021)
Presentation / Conference Contribution

According to United Nations, by 2050 over 20% of the population will be over 65 years old. Ensuring that our ageing population stays independent and healthy for as long as possible requires higher numbers of health and social care professionals than...

Standards and regulations for physically assistive robots**Research supported by Lloyds Register Foundation, under the Assuring Antonomy International Programme (2021)
Presentation / Conference Contribution

In this paper we consider the regulations that currently exist in relation to supporting people in the home and in different care settings. Using existing standards and guidelines that relate to assistive technology and care in the UK, we consider wh...

Towards an ontological framework for environmental survey hazard analysis of autonomous systems (2021)
Presentation / Conference Contribution

This paper presents current progress in the development of Environmental Survey Hazard Analysis (ESHA), a method of preliminary hazard identification aimed at autonomous system application problems. In addition to performing their design mission, aut... Read More about Towards an ontological framework for environmental survey hazard analysis of autonomous systems.

Towards the safety of human-in-the-loop robotics: Challenges and opportunities for safety assurance of robotic co-workers' (2014)
Presentation / Conference Contribution

The success of the human-robot co-worker team in a flexible manufacturing environment where robots learn from demonstration heavily relies on the correct and safe operation of the robot. How this can be achieved is a challenge that requires addressin...

Building safer robots: Safety driven control (2012)
Journal Article

In recent years there has been a concerted effort to address many of the safety issues associated with physical human-robot interaction (pHRI). However, a number of challenges remain. For personal robots, and those intended to operate in unstructured... Read More about Building safer robots: Safety driven control.

Online hazard analysis for autonomous robots (2011)
Presentation / Conference Contribution

Robotic systems require rigorous analysis at all stages of development to ensure system safety. The manufacturing industry has developed many of the robotic design methods used today. These methods were adapted from design practices taken from other... Read More about Online hazard analysis for autonomous robots.

Safety control architecture for personal robots: Behavioural suppression with deliberative control (2010)
Presentation / Conference Contribution

This paper presents a novel robot control architecture for use with personal robots, and argues its potential for improving the safety of these types of system, when compared to existing approaches. The proposed architecture design separates the cont... Read More about Safety control architecture for personal robots: Behavioural suppression with deliberative control.

Towards the development of international safety standards for human robot interaction (2010)
Journal Article

This paper is an overview of the work being performed by the ISO committee TC184/SC2 "Robots and Robotic Devices". SC2 is developing safety standards for robotic applications in personal and medical care, as well as revising existing industrial robot...

Towards the application of swarm intelligence in safety critical systems (2006)
Presentation / Conference Contribution

Swarm Intelligence provides us with a powerful new paradigm for building fully distributed de-centralised systems in which overall system functionality emerges from the interaction of individual agents with each other and with their environment. Such... Read More about Towards the application of swarm intelligence in safety critical systems.

Designing intelligent control systems for safety critical applications (2006)
Presentation / Conference Contribution

This paper presents a design methodology for behaviour-based intelligent control systems, which we argue is suited to safety critical applications. The methodology has a formal basis, and uses dynamical systems theory to prove system safety propertie... Read More about Designing intelligent control systems for safety critical applications.

A methodology for provably stable behaviour-based intelligent control (2006)
Journal Article

This paper presents a design methodology for a class of behaviour-based control systems, arguing its potential for application to safety critical systems. We propose a formal basis for subsumption architecture design based on two extensions to Lyapun... Read More about A methodology for provably stable behaviour-based intelligent control.

Towards dependable swarms and a new discipline of swarm engineering (2005)
Presentation / Conference Contribution

This review paper sets out to explore the question of how future complex engineered systems based upon the swarm intelligence paradigm could be assured for dependability. The paper introduces the new concept of 'swarm engineering': a fusion of depend... Read More about Towards dependable swarms and a new discipline of swarm engineering.

Towards dependable swarms and new discipline of swarm engineering (2004)
Presentation / Conference Contribution

The original shorter paper was given as an invited talk at the SAB '04 workshop on Swarm Robotics. Selected papers were invited to be extended and following further full review were published in this volume in the highly-regarded 'state of the art re...

Direct Lyapunov design - A synthesis procedure for motor schema using a second-order Lyapunov stability theorem (2002)
Presentation / Conference Contribution

In this paper we propose a new procedure for construction of motor schema typically used in behaviour-based robotics. The procedure reverses the standard stability analysis approach by searching for a
control function to fit a pre-defined Lyapunov f... Read More about Direct Lyapunov design - A synthesis procedure for motor schema using a second-order Lyapunov stability theorem.
