摘要： Surgical techniques have evolved over the past few decades, and minimally invasive surgery has been rapidly adapted to become a preferred operative approach for treating colorectal diseases. However, many of the procedures remain a technical challenge for surgeons to perform laparoscopically, which has prompted the development of robotic platforms. Robotic surgery has been introduced as the latest advance in minimally invasive surgery. The present article provides an overview of robotic rectal surgery and describes many advances that have been made in the field over the past two decades. More specifically, the introduction of the robotic platform and its benefits, and the limitations of current robotic technology, are discussed. Although the main advantages of robotic surgery over conventional laparoscopy appear to be lower conversion rates and better surgical specimen quality, oncological and functional outcomes appear to be similar to those of other alternatives. Other potential benefits include earlier recovery of voiding and sexual function after robotic total mesorectal excision. Nevertheless, the costs and lack of haptic feedback remain the primary limitations to the widespread use of robotic technology in the field.

摘要： This study compared the pedagogical effects of educational robot development and the block based programming perspectives, which are used in programming education, on middle school students. Its participants were 78 sixth graders. Considering the students' preferences, 38 students were assigned to the experimental group, which studied with robotics (Lego EV3) sets, and 40 students were assigned to the control group, which studied with block-based programming environment (Scratch). All the topics of the programming unit, which are shown in the methods section, were taught to both groups for 10 weeks using the two different approaches. The change created by the implementation between the groups was tested for academic achievement, computational thinking skill efficacy perceptions, and conceptual knowledge levels. The results indicate that educational robotics develop middle school students' academic achievement and computational thinking skill efficacy perceptions more effectively than block-based programming environments. The connections between the concepts of the students who did robotics were also found to be more solid than those who worked with block-based software.

摘要： Recent studies in social robotics show that it can provide economic efficiency and growth in domains such as retail, entertainment, and active and assisted living (AAL). Recent work also highlights that users have the expectation of affordable social robotics platforms, providing focused and specific assistance in a robust manner. In this paper, we present the AMIRO social robotics framework, designed in a modular and robust way for assistive care scenarios. The framework includes robotic services for navigation, person detection and recognition, multi-lingual natural language interaction and dialogue management, as well as activity recognition and general behavior composition. We present AMIRO platform independent implementation based on a Robot Operating System (ROS). We focus on quantitative evaluations of each functionality module, providing discussions on their performance in different settings and the possible improvements. We showcase the deployment of the AMIRO framework on a popular social robotics platform-the Pepper robot-and present the experience of developing a complex user interaction scenario, employing all available functionality modules within AMIRO.

摘要： In the past decade, the use of soft, deformable materials has gained widespread interest due to their potential to carry out tasks in unstructured environments, such as grasping or manipulating objects with a wide variety of shapes and sizes, locomotion in irregular terrains, and enabling safe and flexible interactions between humans and robots. This emerging research field, generally known as soft robotics, also pushes the boundaries of visionary research topics, such as self-growing and self-healing robotic systems.

摘要： The research community of human-robot interaction relies on theories and phenomena from the social sciences in order to study and validate robotic developments in interaction. These studies mainly concerned one (human) on one (robot) interactions in the past. The present paper shifts the attention to groups and group dynamics and reviews relevant concepts from the social sciences: ingroup identification (I), cohesion (C) and entitativity (E). Ubiquitous robots will be part of larger social settings in the near future. A conceptual framework, the I-C-E framework, is proposed as a theoretical foundation for group (dynamics) research in HRI. Additionally, we present methods and possible measures for these relevant concepts and outline topics for future research.

摘要： The task of this essay is to respond to the question concerning robots and responsibility-to answer for the way that we understand, debate, and decide who or what is able to answer for decisions and actions undertaken by increasingly interactive, autonomous, and sociable mechanisms. The analysis proceeds through three steps or movements. (1) It begins by critically examining the instrumental theory of technology, which determines the way one typically deals with and responds to the question of responsibility when it involves technology. (2) It then considers three instances where recent innovations in robotics challenge this standard operating procedure by opening gaps in the usual way of assigning responsibility. The innovations considered in this section include: autonomous technology, machine learning, and social robots. (3) The essay concludes by evaluating the three different responses-instrumentalism 2.0, machine ethics, and hybrid responsibility-that have been made in face of these difficulties in an effort to map out the opportunities and challenges of and for responsible robotics.

摘要： As the aim of the responsible robotics initiative is to ensure that responsible practices are inculcated within each stage of design, development and use, this impetus is undergirded by the alignment of ethical and legal considerations towards socially beneficial ends. While every effort should be expended to ensure that issues of responsibility are addressed at each stage of technological progression, irresponsibility (meaning a lack of responsibility) is inherent within the nature of robotics technologies from a theoretical perspective that threatens to thwart the endeavour. This is because the concept of responsibility, despite being treated as such, is not monolithic: rather this seemingly unified concept consists of converging and confluent concepts that shape the idea of what we colloquially call responsibility. From a different perspective, robotics will be simultaneously responsible and irresponsible depending on the particular concept of responsibility that is foregrounded: an observation that cuts against the grain of the drive towards responsible robotics. This problem is further compounded by responsible design and development as contrasted to responsible use. From a different perspective, the difficulty in defining the concept of responsibility in robotics is because human responsibility is the main frame of reference. Robotic systems are increasingly expected to achieve the human-level performance, including the capacities associated with responsibility and other criteria which are necessary to act responsibly. This subsists within a larger phenomenon where the difference between humans and non-humans, be it animals or artificial systems, appears to be increasingly blurred, thereby disrupting orthodox understandings of responsibility. This paper seeks to supplement the responsible robotics impulse by proposing a complementary set of human rights directed specifically against the harms arising from robotic and artificial intelligence (AI) technologies.

摘要： Healable soft robotic systems have been developed by constructing flexible membranes out of Diels-Alder (DA) polymer networks. In these components, relatively large amounts of damage, on the centimeter scale, can be healed, provided that the temperature is increased to 80-90 degrees C. This article presents a new DA polymer network that can heal at room temperature through a smart design of the network that increases the molecular mobility in the material. This new material is used to develop the first healable soft robotic prototype that can autonomously recover from severe, realistic damage. The soft pneumatic hand can recover from various types of injuries, including being cut completely in half, without the need for a temperature increase. After healing, the performance of the soft robotic prototype is recovered.
