摘要： 以管道机器人(Pipeline inspection gauge,PIG)为载体的内检测技术是保障油气管道安全运输的重要手段。针对管内高压流体作用下,管道机器人在冲击管内环焊缝过程中产生的动力学行为突变问题。建立了管道周向受限空间中基于Kelvin弹簧阻尼的管道机器人密封盘等效动力学模型,结合管道机器人本体建立了多体系管道机器人动力学模型;详细推导了管道机器人轴向振动微分方程,以及管内流体的流动方程;并使用Matlab/Simulink与Adams进行流固耦合仿真,作为重要的工艺参数之一,研究了管道机器人速度改变时,其在冲击环焊缝过程中的动力学响应情况。结果表明:所建立的密封盘及管道机器人动力学模型能够很好地表征密封盘在管道轴向、径向以及周向的力学特性;运行速度越快,管道机器人通过环焊缝引起的轴向振动越剧烈,冲击振动越明显;而垂向和俯仰振动现象随运动速度增大而显著减弱。

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.
