Soft robotics with new designs, fabrication technologies and control strategies inspired by nature have been totally changing our view on robotics. To fully exploit their potential in practical applications, untethered designs are preferred in implementation. However, hindered by the limited thermal/mechanical performance of soft materials, it has been always challenging for researchers to implement untethered solutions, which generally involve rigid forms of high energy-density power sources or high energy-density processes. A number of insects in nature, such as rove beetles, can gain a burst of kinetic energy from the induced surface-energy gradient on water to return to their familiar habitats, which is generally known as Marangoni propulsion. Inspired by such a behavior, we report the agile untethered mobility of a fully soft robot in liquid based on induced energy gradients and also develop corresponding fabrication and maneuvering strategies. The robot can reach a speed of 5.5 body lengths per second, which is 7-fold more than the best reported, 0.69 (body length per second), in the previous work on untethered soft robots in liquid by far. Further controlling the robots, we demonstrate a soft-robot swarm that can approach a target simultaneously to assure a hit with high accuracy. Without employing any high energy-density power sources or processes, our robot exhibits many attractive merits, such as quietness, no mechanical wear, no thermal fatigue, invisibility and ease of robot fabrication, which may potentially impact many fields in the future. 相似文献

Social roboticists design their robots to function as social agents in interaction with humans and other robots. Although we do not deny that the robot's design features are crucial for attaining this aim, we point to the relevance of spatial organization and coordination between the robot and the humans who interact with it. We recover these interactions through an observational study of a social robotics laboratory and examine them by applying a multimodal interactional analysis to two moments of robotics practice. We describe the vital role of roboticists and of the group of preverbal infants, who are involved in a robot's design activity, and we argue that the robot's social character is intrinsically related to the subtleties of human interactional moves in laboratories of social robotics. This human involvement in the robot's social agency is not simply controlled by individual will. Instead, the human-machine couplings are demanded by the situational dynamics in which the robot is lodged. 相似文献

Current uses of robots in classrooms are reviewed and used to characterise four scenarios: (s1) Robot as Classroom Teacher; (s2) Robot as Companion and Peer; (s3) Robot as Care-eliciting Companion; and (s4) Telepresence Robot Teacher. The main ethical concerns associated with robot teachers are identified as: privacy; attachment, deception, and loss of human contact; and control and accountability. These are discussed in terms of the four identified scenarios. It is argued that classroom robots are likely to impact children’s’ privacy, especially when they masquerade as their friends and companions, when sensors are used to measure children’s responses, and when records are kept. Social robots designed to appear as if they understand and care for humans necessarily involve some deception (itself a complex notion), and could increase the risk of reduced human contact. Children could form attachments to robot companions (s2 and s3), or robot teachers (s1) and this could have a deleterious effect on their social development. There are also concerns about the ability, and use of robots to control or make decisions about children’s behaviour in the classroom. It is concluded that there are good reasons not to welcome fully fledged robot teachers (s1), and that robot companions (s2 and 3) should be given a cautious welcome at best. The limited circumstances in which robots could be used in the classroom to improve the human condition by offering otherwise unavailable educational experiences are discussed. 相似文献

It should not be a surprise in the near future to encounter either a personal or a professional service robot in our homes and/or our work places: according to the International Federation for Robots, there will be approx 35 million service robots at work by 2018. Given that individuals will interact and even cooperate with these service robots, their design and development demand ethical attention. With this in mind I suggest the use of an approach for incorporating ethics into the design process of robots known as Care Centered Value Sensitive Design (CCVSD). Although this approach was originally and intentionally designed for the healthcare domain, the aim of this paper is to present a preliminary study of how personal and professional service robots might also be evaluated using the CCVSD approach. The normative foundations for CCVSD come from its reliance on the care ethics tradition and in particular the use of care practices for: (1) structuring the analysis and, (2) determining the values of ethical import. To apply CCVSD outside of healthcare one must show that the robot has been integrated into a care practice. Accordingly, the practice into which the robot is to be used must be assessed and shown to meet the conditions of a care practice. By investigating the foundations of the approach I hope to show why it may be applicable for service robots and further to give examples of current robot prototypes that can and cannot be evaluated using CCVSD. 相似文献

Robotic systems consisting of a neuron culture grown on a multielectrode array (MEA) which is connected to a virtual or mechanical robot have been studied for approximately 15 years. It is hoped that these MEA-based robots will be able to address the problem that robots based on conventional computer technology are not very good at adapting to surprising or unusual situations, at least not when compared to biological organisms. It is also hoped that insights gained from MEA-based robotics can have applications within human enhancement and medicine. In this paper, I argue that researchers within this field risk overstating their results by not paying enough attention to fundamental challenges within the field. In particular, I investigate three problems: the coding problem, the embodiment problem and the training problem. I argue that none of these problems have been solved and that they are not likely to be solved within the field. After that, I discuss whether MEA-based robotics should be considered pop science. Finally, I investigate the ethical aspects of this research. 相似文献

This paper explores the relationship between dignity and robot care for older people. It highlights the disquiet that is often expressed about failures to maintain the dignity of vulnerable older people, but points out some of the contradictory uses of the word ‘dignity’. Certain authors have resolved these contradictions by identifying different senses of dignity; contrasting the inviolable dignity inherent in human life to other forms of dignity which can be present to varying degrees. The capability approach (CA) is introduced as a different but tangible account of what it means to live a life worthy of human dignity. It is used here as a framework for the assessment of the possible effects of eldercare robots on human dignity. The CA enables the identification of circumstances in which robots could enhance dignity by expanding the set of capabilities that are accessible to frail older people. At the same time, it is also possible within its framework to identify ways in which robots could have a negative impact, by impeding the access of older people to essential capabilities. It is concluded that the CA has some advantages over other accounts of dignity, but that further work and empirical study is needed in order to adapt it to the particular circumstances and concerns of those in the latter part of their lives. 相似文献

The control problem of the cooperative motion of a two-link dual arm robot during handling and transportation of an object was studied in this paper. Since these types of robots are frequently preferred for hazardous applications such as transportation of radioactive materials and disposal of explosives, a robust non-chattering sliding mode controller (SMC) improved by a multiple-input multiple-output (MIMO) fuzzy logic unit was applied to the robot to track the desired trajectory with high accuracy and transport the load safely. In order to assess the performance of the proposed MIMO fuzzy sliding mode controller (MIMO-FSMC) in presence of parameter variations and external disturbances, a sudden load variation and noise were introduced to the robot system. If compared with classical SMC, tracking errors with smaller magnitudes and faster convergence to zero were obtained by using the proposed MIMO-FSMC. Numerical results suggest that this type of control method may safely be used for cooperative motion control of dual arm robots in load handling and transport applications in hazardous environments with high accuracy. 相似文献

Industrial and domestic robotics provide fascinating and relevant perspective insights into current and possible trajectories for the development of contemporary societies. While industrial robotics has found its place since the 1960s, domestic robotics wherein humans interact with social robots is still an unsettled area. After reviewing data on the diffusion of social robots and on their use, the historical tradition from which social robots come is discussed. This discussion is followed by an analysis of the penetration of social robots in everyday life and the importance of interdisciplinary research is highlighted. 相似文献

This paper offers an ethical framework for the development of robots as home companions that are intended to address the isolation and reduced physical functioning of frail older people with capacity, especially those living alone in a noninstitutional setting. Our ethical framework gives autonomy priority in a list of purposes served by assistive technology in general, and carebots in particular. It first introduces the notion of “presence” and draws a distinction between humanoid multi-function robots and non-humanoid robots to suggest that the former provide a more sophisticated presence than the latter. It then looks at the difference between lower-tech assistive technological support for older people and its benefits, and contrasts these with what robots can offer. This provides some context for the ethical assessment of robotic assistive technology. We then consider what might need to be added to presence to produce care from a companion robot that deals with older people’s reduced functioning and isolation. Finally, we outline and explain our ethical framework. We discuss how it combines sometimes conflicting values that the design of a carebot might incorporate, if informed by an analysis of the different roles that can be served by a companion robot. 相似文献

The sustainability of social robotics, like other ambitious research programs, depends on the identification of lines of inquiry that are coherent with its visionary goals while satisfying more stringent constraints of feasibility and near-term payoffs. Within these constraints, this article outlines one line of inquiry that seems especially viable: development of a society of robots operating within the physical environments of everyday human life, developing rich robot–robot social exchanges, and yet, refraining from any physical contact with human beings. To pursue this line of inquiry effectively, sustained interactions between specialized research communities in robotics are needed. Notably, suitable robotic hand design and control principles must be adopted to achieve proper robotic manipulation of objects designed for human hands that one finds in human habitats. The Pisa-IIT SoftHand project promises to meet these manipulation needs by a principled combination of sensorimotor synergies and soft robotics actuation, which aims at capturing how the biomechanical structure and neural control strategies of the human hand interact so as to simplify and solve both control and sensing problems. 相似文献

The growing proportion of elderly people in society, together with recent advances in robotics, makes the use of robots in
elder care increasingly likely. We outline developments in the areas of robot applications for assisting the elderly and their
carers, for monitoring their health and safety, and for providing them with companionship. Despite the possible benefits,
we raise and discuss six main ethical concerns associated with: (1) the potential reduction in the amount of human contact;
(2) an increase in the feelings of objectification and loss of control; (3) a loss of privacy; (4) a loss of personal liberty;
(5) deception and infantilisation; (6) the circumstances in which elderly people should be allowed to control robots. We conclude
by balancing the care benefits against the ethical costs. If introduced with foresight and careful guidelines, robots and
robotic technology could improve the lives of the elderly, reducing their dependence, and creating more opportunities for
social interaction 相似文献

This paper presents a decentralized navigation method with a leader robot guiding a robotic swarm and considers the possible occurrence of a failure. Multi-robot systems have attracted attention in part because they can maintain their performance as a swarm even when some robots fail. Such systems are also expected to work well in environments where a disaster has occurred, given that the chance of robot crashes is high in such situations. Therefore, it is important to design a navigation method that considers the possibility of failures so that the surviving robots in a swarm will not be impaired because of failed robots. In this paper, we design connectivity maintenance and a repair method for swarm robots in which each robot utilizes only local information. We then prove that the proposed method ensures the swarm follows the movement of a leader robot and reconstructs connectivity in the case one of the robots fails. Finally, we present experimental and numerical results confirming the effectiveness of the proposed method. 相似文献

This article reports findings from a usability and user experience evaluations conducted in the last 2 years of a 4-year assistive robotics research project using the Kompai robot. It focuses on the evaluations that were conducted with older adults in an assisted living studio in the United Kingdom (which was arranged as an open plan studio apartment), a UK residential care home, and an older couple's own home in the Netherlands over 2 days. It examines emergent adaptive human behaviour in human-robot interaction (HRI) to consider whether we are approaching the embodiment and functionality of service robots correctly. It discusses possible improvements that could be made at the systems level that better exploit people's natural ability to adapt and find workarounds to technologies and their limitations. 相似文献
