摘要： 目的为了更全面地了解码垛机器人的动态性能,分析码垛机器人臂部变形对其运动精度的影响。方法以ABB的IRB760型机器人为分析对象,运用Lagrange法计算得到其刚柔耦合动力学模型,然后运用ADAMS软件对机器人在一个工作周期内的运动过程,分别进行刚体动力学仿真和刚柔耦合动力学仿真。结果机器人末端执行器柔性仿真的速度曲线与刚性仿真的速度曲线基本相同,在运行过程中速度变化平稳连续,无突变,而位移曲线机器人运行状态改变时有区别,柔性仿真的加速度波动较大。结论码垛机器人臂部柔性变形对机器人的运行精度及稳定性影响较大,采用刚柔耦合方法可以更加准确地分析码垛机器人的运行状态。

摘要： The IEEE1872.2 Autonomous Robotics (AuR) Ontology Working Group has recently developed the AuR ontology standard. This standard is a logical extension to IEEE 1872–2015 Standard Ontologies for Robotics and Automation, core ontology or robotics and automation (CORA).

摘要： A humanoid robot named 'Sophia' has sparked controversy since it has been given citizenship and has done media performances all over the world. The company that made the robot, Hanson Robotics, has touted Sophia as the future of artificial intelligence (AI). Robot scientists and philosophers have been more pessimistic about its capabilities, describing Sophia as a sophisticated puppet or chatbot. Looking behind the rhetoric about Sophia's citizenship and intelligence and going beyond recent discussions on the moral status or legal personhood of AI robots, we analyse the performativity of Sophia from the perspective of what we call 'political choreography': drawing on phenomenological approaches to performance-oriented philosophy of technology. This paper proposes to interpret and discuss the world tour of Sophia as a political choreography that boosts the rise of the social robot market, rather than a statement about robot citizenship or artificial intelligence. We argue that the media performances of the Sophia robot were choreographed to advance specific political interests. We illustrate our philosophical discussion with media material of the Sophia performance, which helps us to explore the mechanisms through which the media spectacle functions hand in hand with advancing the economic interests of technology industries and their governmental promotors. Using a phenomenological approach and attending to the movement of robots, we also criticize the notion of 'embodied intelligence' used in the context of social robotics and AI. In this way, we put the discussions about the robot's rights or citizenship in the context of AI politics and economics.

摘要： There is a growing need in the tourism and hospitality literature to harmonise service robots and artificial intelligence's (AI) meaning and foundations, while also offering guidance on future discussions and research. We operationalize MacInnis'Journal of Marketing, 75(4), 136-154, (2011) conceptual contribution to derive insights regarding service robots in the tourism and hospitality domain. This paper adopts an interdisciplinary stance and integrates insights from the tourism, hospitality, philosophy, psychology, sociology, management, robotics, information technology and marketing fields. Service robotics and related tourism and hospitality research follow three basic themes: deployment, acceptance and ethical considerations. The findings on the use of service robotics are subsequently delineated and a summary of the tourism and hospitality field's current research needs is provided.

摘要： According to the World Bank review, National Oil Companies (NOCs) control approximately 90% of the world's oil reserves and 75% of production (similar numbers apply to gas) and many major oil and gas infrastructure systems. However, NOCs fall behind many smaller companies in terms of innovation. The reason is the closed nature of their business, which constrains innovations. It has been suggested that this problem can be solved by the application of an "Open Innovation" paradigm. The concepts of Open Innovation suggest firms who would like to be more innovative to use internal as well as external sources for their idea generation. (Ibrahimov in Open innovation and application to petroleum industry. IFAC Papersonline, 2018). However, this is not easy to deploy due to these organizations' traditions, values, and institutional culture, which act as innovation obstacles in those companies. Innovations should be "Open" to find better solutions but should be "Closed" to fit with the cultural requirements of NOCs. This contradiction needs to be solved quickly for the sake of innovation, which is the key to ensure environmental and societal benefits and to prevent further harm. This article stresses the importance of Open Innovation in the petrochemical industry and discusses the difficulties for the industry to embrace it, especially in light of the advances in intelligent robotic systems applications in the sector. The questions are: How should large NOCs adopt innovations and become more open to innovation so that the best intelligent automatic solutions are adopted in such contexts? Is there a theory of knowledge and innovation that can solve the contradictions between Closed versus Open Innovation? This paper posits that a solution to the contradictions surrounding innovations in NOCs could be found in Teorija rezheniya izobretatelskih zadach (TRIZ) (Theory of inventive problem solving), which has been used for decades to overcome contradictions and to develop inventiv

摘要： Dual quaternion algebra and its application to robotics have attracted considerable interest in the last two decades. Dual quaternions have great geometric appeal and easily capture physical phenomena inside an algebraic framework, which is useful for both robot modeling and control. Mathematical objects, such as points, lines, planes, infinite cylinders, spheres, coordinate systems, twists, and wrenches, are all well defined as dual quaternions. Therefore, simple operators are used to represent those objects in different frames, and operations, such as inner products and cross products, are used to extract useful geometric relationships among them.

摘要： BACKGROUND Conventional methods used to evaluate the activity of catalysts are time consuming and tedious, which only several catalysts can successfully be discovered. By employing robotics, this approach can be shorted tremendously. A robotics-assisted high-throughput system for the fast and effective catalytic evaluation of Pd- and Au-polyvinylpyrrolidone (PVP) nanoparticles (NPs) was investigated. RESULTS Palladium and gold PVP NPs were synthesised by employing ethylene glycol in the polyol method. These NPs were evaluated for the oxidation of morin using a high-throughput system, including a liquid handling robot, a 96-well plate and a microplate reader. The catalyst concentration variation step for both catalysts (Pd- and Au-PVP NPs) was performed in one experiment in a 96-well plate. A concentration range, including 12 concentrations in four replicates, was investigated simultaneously. Therefore, with one experiment, the optimal concentration of both catalysts could be determined. A similar approach was followed for the concentration variation steps of morin and hydrogen peroxide at different temperatures. This was done to determine the effect of concentration on the observed rate (k(obs)). CONCLUSION The catalytic oxidative degradation of morin can be investigated in a fast and effective way by employing robotics and a high-throughput system. This system can also be applied to screen catalysts (homogeneous and heterogeneous catalyst) and the parallel synthesis of nanoparticles - particularly dendrimer-encapsulated nanoparticles.
