Internet of robotic things : converging sensing/actuating, hypoconnectivity, artificial intelligence and IoT Platforms

The Internet of Things (IoT) concept is evolving rapidly and influencing newdevelopments in various application domains, such as the Internet of MobileThings (IoMT), Autonomous Internet of Things (A-IoT), Autonomous Systemof Things (ASoT), Internet of Autonomous Things (IoAT), Internetof Things Clouds (IoT-C) and the Internet of Robotic Things (IoRT) etc.that are progressing/advancing by using IoT technology. The IoT influencerepresents new development and deployment challenges in different areassuch as seamless platform integration, context based cognitive network integration,new mobile sensor/actuator network paradigms, things identification(addressing, naming in IoT) and dynamic things discoverability and manyothers. The IoRT represents new convergence challenges and their need to be addressed, in one side the programmability and the communication ofmultiple heterogeneous mobile/autonomous/robotic things for cooperating,their coordination, configuration, exchange of information, security, safetyand protection. Developments in IoT heterogeneous parallel processing/communication and dynamic systems based on parallelism and concurrencyrequire new ideas for integrating the intelligent “devices”, collaborativerobots (COBOTS), into IoT applications. Dynamic maintainability, selfhealing,self-repair of resources, changing resource state, (re-) configurationand context based IoT systems for service implementation and integrationwith IoT network service composition are of paramount importance whennew “cognitive devices” are becoming active participants in IoT applications.This chapter aims to be an overview of the IoRT concept, technologies,architectures and applications and to provide a comprehensive coverage offuture challenges, developments and applications

Miniature mobile sensor platforms for condition monitoring of structures

In this paper, a wireless, multisensor inspection system for nondestructive evaluation (NDE) of materials is described. The sensor configuration enables two inspection modes-magnetic (flux leakage and eddy current) and noncontact ultrasound. Each is designed to function in a complementary manner, maximizing the potential for detection of both surface and internal defects. Particular emphasis is placed on the generic architecture of a novel, intelligent sensor platform, and its positioning on the structure under test. The sensor units are capable of wireless communication with a remote host computer, which controls manipulation and data interpretation. Results are presented in the form of automatic scans with different NDE sensors in a series of experiments on thin plate structures. To highlight the advantage of utilizing multiple inspection modalities, data fusion approaches are employed to combine data collected by complementary sensor systems. Fusion of data is shown to demonstrate the potential for improved inspection reliability

White paper - Agricultural Robotics: The Future of Robotic Agriculture

Agri-Food is the largest manufacturing sector in the UK. It supports a food chain that generates over £108bn p.a., with 3.9m employees in a truly international industry and exports £20bn of UK manufactured goods. However, the global food chain is under pressure from population growth, climate change, political pressures affecting migration, population drift from rural to urban regions and the demographics of an aging global population. These challenges are recognised in the UK Industrial Strategy white paper and backed by significant investment via a wave 2 Industrial Challenge Fund Investment (“Transforming Food Production: from Farm to Fork”). RAS and associated digital technologies are now seen as enablers of this critical food chain transformation. To meet these challenges, here we review the state of the art of the application of RAS in Agri-Food production and explore research and innovation needs to ensure novel advanced robotic and autonomous reach their full potential and deliver necessary impacts. The opportunities for RAS range from; the development of field robots that can assist workers by carrying weights and conduct agricultural operations such as crop and animal sensing, weeding and drilling; integration of autonomous system technologies into existing farm operational equipment such as tractors; robotic systems to harvest crops and conduct complex dextrous operations; the use of collaborative and “human in the loop” robotic applications to augment worker productivity and advanced robotic applications, including the use of soft robotics, to drive productivity beyond the farm gate into the factory and retail environment. RAS technology has the potential to transform food production and the UK has the potential to establish global leadership within the domain. However, there are particular barriers to overcome to secure this vision: 1.The UK RAS community with an interest in Agri-Food is small and highly dispersed. There is an urgent need to defragment and then expand the community.2.The UK RAS community has no specific training paths or Centres for Doctoral Training to provide trained human resource capacity within Agri-Food.3.While there has been substantial government investment in translational activities at high Technology Readiness Levels (TRLs), there is insufficient ongoing basic research in Agri-Food RAS at low TRLs to underpin onward innovation delivery for industry.4.There is a concern that RAS for Agri-Food is not realising its full potential, as the projects being commissioned currently are too few and too small-scale. RAS challenges often involve the complex integration of multiple discrete technologies (e.g. navigation, safe operation, multimodal sensing, automated perception, grasping and manipulation, perception). There is a need to further develop these discrete technologies but also to deliver large-scale industrial applications that resolve integration and interoperability issues. The UK community needs to undertake a few well-chosen large-scale and collaborative “moon shot” projects.5.The successful delivery of RAS projects within Agri-Food requires close collaboration between the RAS community and with academic and industry practitioners. For example, the breeding of crops with novel phenotypes, such as fruits which are easy to see and pick by robots, may simplify and accelerate the application of RAS technologies. Therefore, there is an urgent need to seek new ways to create RAS and Agri-Food domain networks that can work collaboratively to address key challenges. This is especially important for Agri-Food since success in the sector requires highly complex cross-disciplinary activity. Furthermore, within UKRI most of the Research Councils (EPSRC, BBSRC, NERC, STFC, ESRC and MRC) and Innovate UK directly fund work in Agri-Food, but as yet there is no coordinated and integrated Agri-Food research policy per se. Our vision is a new generation of smart, flexible, robust, compliant, interconnected robotic systems working seamlessly alongside their human co-workers in farms and food factories. Teams of multi-modal, interoperable robotic systems will self-organise and coordinate their activities with the “human in the loop”. Electric farm and factory robots with interchangeable tools, including low-tillage solutions, novel soft robotic grasping technologies and sensors, will support the sustainable intensification of agriculture, drive manufacturing productivity and underpin future food security. To deliver this vision the research and innovation needs include the development of robust robotic platforms, suited to agricultural environments, and improved capabilities for sensing and perception, planning and coordination, manipulation and grasping, learning and adaptation, interoperability between robots and existing machinery, and human-robot collaboration, including the key issues of safety and user acceptance. Technology adoption is likely to occur in measured steps. Most farmers and food producers will need technologies that can be introduced gradually, alongside and within their existing production systems. Thus, for the foreseeable future, humans and robots will frequently operate collaboratively to perform tasks, and that collaboration must be safe. There will be a transition period in which humans and robots work together as first simple and then more complex parts of work are conducted by robots; driving productivity and enabling human jobs to move up the value chain

Safe, Remote-Access Swarm Robotics Research on the Robotarium

This paper describes the development of the Robotarium -- a remotely accessible, multi-robot research facility. The impetus behind the Robotarium is that multi-robot testbeds constitute an integral and essential part of the multi-agent research cycle, yet they are expensive, complex, and time-consuming to develop, operate, and maintain. These resource constraints, in turn, limit access for large groups of researchers and students, which is what the Robotarium is remedying by providing users with remote access to a state-of-the-art multi-robot test facility. This paper details the design and operation of the Robotarium as well as connects these to the particular considerations one must take when making complex hardware remotely accessible. In particular, safety must be built in already at the design phase without overly constraining which coordinated control programs the users can upload and execute, which calls for minimally invasive safety routines with provable performance guarantees.Comment: 13 pages, 7 figures, 3 code samples, 72 reference

Ubiquitous supercomputing : design and development of enabling technologies for multi-robot systems rethinking supercomputing

Supercomputing, also known as High Performance Computing (HPC), is almost everywhere (ubiquitous), from the small widget in your phone telling you that today will be a sunny day, up to the next great contribution to the understanding of the origins of the universe.However, there is a field where supercomputing has been only slightly explored - robotics. Other than attempts to optimize complex robotics tasks, the two forces lack an effective alignment and a purposeful long-term contract. With advancements in miniaturization, communications and the appearance of powerful, energy and weight optimized embedded computing boards, a next logical transition corresponds to the creation of clusters of robots, a set of robotic entities that behave similarly as a supercomputer does. Yet, there is key aspect regarding our current understanding of what supercomputing means, or is useful for, that this work aims to redefine. For decades, supercomputing has been solely intended as a computing efficiency mechanism i.e. decreasing the computing time for complex tasks. While such train of thought have led to countless findings, supercomputing is more than that, because in order to provide the capacity of solving most problems quickly, another complete set of features must be provided, a set of features that can also be exploited in contexts such as robotics and that ultimately transform a set of independent entities into a cohesive unit.This thesis aims at rethinking what supercomputing means and to devise strategies to effectively set its inclusion within the robotics realm, contributing therefore to the ubiquity of supercomputing, the first main ideal of this work. With this in mind, a state of the art concerning previous attempts to mix robotics and HPC will be outlined, followed by the proposal of High Performance Robotic Computing (HPRC), a new concept mapping supercomputing to the nuances of multi-robot systems. HPRC can be thought as supercomputing in the edge and while this approach will provide all kind of advantages, in certain applications it might not be enough since interaction with external infrastructures will be required or desired. To facilitate such interaction, this thesis proposes the concept of ubiquitous supercomputing as the union of HPC, HPRC and two more type of entities, computing-less devices (e.g. sensor networks, etc.) and humans.The results of this thesis include the ubiquitous supercomputing ontology and an enabling technology depicted as The ARCHADE. The technology serves as a middleware between a mission and a supercomputing infrastructure and as a framework to facilitate the execution of any type of mission, i.e. precision agriculture, entertainment, inspection and monitoring, etc. Furthermore, the results of the execution of a set of missions are discussed.By integrating supercomputing and robotics, a second ideal is targeted, ubiquitous robotics, i.e. the use of robots in all kind of applications. Correspondingly, a review of existing ubiquitous robotics frameworks is presented and based upon its conclusions, The ARCHADE's design and development have followed the guidelines for current and future solutions. Furthermore, The ARCHADE is based on a rethought supercomputing where performance is not the only feature to be provided by ubiquitous supercomputing systems. However, performance indicators will be discussed, along with those related to other supercomputing features.Supercomputing has been an excellent ally for scientific exploration and not so long ago for commercial activities, leading to all kind of improvements in our lives, in our society and in our future. With the results of this thesis, the joining of two fields, two forces previously disconnected because of their philosophical approaches and their divergent backgrounds, holds enormous potential to open up our imagination for all kind of new applications and for a world where robotics and supercomputing are everywhere.La supercomputación, también conocida como Computación de Alto Rendimiento (HPC por sus siglas en inglés) puede encontrarse en casi cualquier lugar (ubicua), desde el widget en tu teléfono diciéndote que hoy será un día soleado, hasta la siguiente gran contribución al entendimiento de los orígenes del universo. Sin embargo, hay un campo en el que ha sido poco explorada - la robótica. Más allá de intentos de optimizar tareas robóticas complejas, las dos fuerzas carecen de un contrato a largo plazo. Dado los avances en miniaturización, comunicaciones y la aparición de potentes computadores embebidos, optimizados en peso y energía, la siguiente transición corresponde a la creación de un cluster de robots, un conjunto de robots que se comportan de manera similar a un supercomputador. No obstante, hay un aspecto clave, con respecto a la comprensión de la supercomputación, que esta tesis pretende redefinir. Durante décadas, la supercomputación ha sido entendida como un mecanismo de eficiencia computacional, es decir para reducir el tiempo de computación de ciertos problemas extremadamente complejos. Si bien este enfoque ha conducido a innumerables hallazgos, la supercomputación es más que eso, porque para proporcionar la capacidad de resolver todo tipo de problemas rápidamente, se debe proporcionar otro conjunto de características que también pueden ser explotadas en la robótica y que transforman un conjunto de robots en una unidad cohesiva. Esta tesis pretende repensar lo que significa la supercomputación y diseñar estrategias para establecer su inclusión dentro del mundo de la robótica, contribuyendo así a su ubicuidad, el principal ideal de este trabajo. Con esto en mente, se presentará un estado del arte relacionado con intentos anteriores de mezclar robótica y HPC, seguido de la propuesta de Computación Robótica de Alto Rendimiento (HPRC, por sus siglas en inglés), un nuevo concepto, que mapea la supercomputación a los matices específicos de los sistemas multi-robot. HPRC puede pensarse como supercomputación en el borde y si bien este enfoque proporcionará todo tipo de ventajas, ciertas aplicaciones requerirán una interacción con infraestructuras externas. Para facilitar dicha interacción, esta tesis propone el concepto de supercomputación ubicua como la unión de HPC, HPRC y dos tipos más de entidades, dispositivos sin computación embebida y seres humanos. Los resultados de esta tesis incluyen la ontología de la supercomputación ubicua y una tecnología llamada The ARCHADE. La tecnología actúa como middleware entre una misión y una infraestructura de supercomputación y como framework para facilitar la ejecución de cualquier tipo de misión, por ejemplo, agricultura de precisión, inspección y monitoreo, etc. Al integrar la supercomputación y la robótica, se busca un segundo ideal, robótica ubicua, es decir el uso de robots en todo tipo de aplicaciones. Correspondientemente, una revisión de frameworks existentes relacionados serán discutidos. El diseño y desarrollo de The ARCHADE ha seguido las pautas y sugerencias encontradas en dicha revisión. Además, The ARCHADE se basa en una supercomputación repensada donde la eficiencia computacional no es la única característica proporcionada a sistemas basados en la tecnología. Sin embargo, se analizarán indicadores de eficiencia computacional, junto con otros indicadores relacionados con otras características de la supercomputación. La supercomputación ha sido un excelente aliado para la exploración científica, conduciendo a todo tipo de mejoras en nuestras vidas, nuestra sociedad y nuestro futuro. Con los resultados de esta tesis, la unión de dos campos, dos fuerzas previamente desconectadas debido a sus enfoques filosóficos y sus antecedentes divergentes, tiene un enorme potencial para abrir nuestra imaginación hacia todo tipo de aplicaciones nuevas y para un mundo donde la robótica y la supercomputación estén en todos lado
