Transport is responsible for around a quarter of global emissions. It is 91% fossil fuel dependent for energy, with emissions remaining stubbornly high, increasing in the EU since 1990 and falling since then by just 15% in the UK. The UK’s National Infrastructure Commission (NIC), in producing its second assessment, a major strategic overview for the next 30 years, emphasises a near universal dependency on electricity and hydrogen to decarbonise transport emissions. Locally distributed energy solutions are not considered part of their approach and neither do they consider where the products proposed for mass adoption – electric vehicles (EVs) are to be manufactured. Embodied carbon emissions are not taken into account, with emissions analysis focused on zero tailpipe emissions. Green gases which can be used in combustion engines and hybrids, harnessing existing supply chains and maintenance service provision, are also not seen as part of the solution, even during transition. Manufacturers are concerned that legislation and policy approaches, such as the Zero Emissions Vehicle Mandate, will lead to off-shoring of production. Zero Emissions Vehicles do not consider tyre emissions, which some research has shown to be many times higher than tailpipe emissions with devastating impacts on ecosystems. The chapter proposes the need for a greater holistic and circular approach to be taken to embodied carbon, mineral and resource utilisation together with biodiversity and planetary impacts.

Social robotics is a rapidly growing application of artificial intelligence (AI) in society, encompassing an expanding range of applications. This paper aims to contribute to the ongoing integration of psychology into social robotics ethics by reviewing current theories and empirical findings related to human–robot interaction (HRI) and addressing critical points of contention within the ethics discourse.

The authors will explore the factors influencing the acceptance of social robots, explore the development of relationships between humans and robots and delve into three prominent controversies: deception, dehumanisation and violence.

The authors first propose design factors allowing for a positive interaction with the robot, and further discuss precise dimensions to evaluate when designing a social robot to ensure ethical design technology, building on the four ethical principles for trustworthy AI. The final section of this paper will outline and offer explicit recommendations for future research endeavours.

This paper provides originality and value to the field of social robotics ethics by integrating psychology into the ethical discourse and offering a comprehensive understanding of HRI. It introduces three ethical dimensions and provides recommendations for implementing them, contributing to the development of ethical design in social robots and trustworthy AI.

This paper aims to provide a full introduction, new classification, comparison and investigation of the challenges as well as applications of layerless 3D printing, which is one of the industry 4.0 pioneers.

Given the significance and novelty of uniform 3D printing, more than 250 publications were collected and reviewed in an unbiased and clear manner.

As a result, the majority of uniform parts printed in polymer form are known up to this point. In a novel division for better researchers’ comprehension, uniform printing systems were classified into three categories: oxygen inhibition (OI), liquid lubrication (LL) and photon penetration (PP), and each was thoroughly investigated. Furthermore, these three approaches were evaluated in terms of printing speed, precision and accuracy, manufacturing scale and cost.

The parameters of each approach were compared independently, and then a practical comparison was conducted among these three approaches. Finally, a variety of technologies, opportunities, challenges and advantages of each significant method, as well as a future outlook for layerless rapid prototyping, are presented.
