    A mission as complex as the Space Exploration Initiative (SEI) cannot succeed without adhering to sound principles in the planning, development, and execution of logistics support for the exploration crews and their mission equipment. While much attention will focus upon the development of reliable, robust, heavy lift launch vehicles, and scientific, technological breakthroughs for SEI, of equal concern is the supportability and sustainability of systems designed for mission operations and crew life support on the lunar and Martian surfaces

    Robotics is the ­new-age domain of technology that deals with bringing a collaboration of all disciplines of sciences and engineering to create a mechanical machine that may or may not work entirely independently but definitely focuses on making human lives much easier. It has repeatedly shown its ability to change lives at home and in the industry. As the field of robotics research grows and reaches new worlds, the military is one area where advances can have a significant impact, and the government is aware of this. Military technology has come a long way from the days where soldiers had to walk into traps, putting their own lives in danger for their fellow soldiers, to today, when soldiers have robots walk into the same traps with possibility and result of zero human casualties. High-risk military operations such as mine detection, bomb defusing, fighter pilot aviation, and entering enemy territory without complete knowledge of what is to come are all tasks that can be programmed in a way that makes them accustomed to scenarios like these, either by intensive machine learning algorithms or artificially intelligent robot systems. Military soldiers are human capital; they are not self-driving robots; they are living beings with emotions, fears, and weaknesses, and they will almost always be unreliable as compared to computers and robots. They are easily affected by environmental effects and are vulnerable to external influences. The government\u27s costs for deployed troops, such as training and salaries, are extremely high. As a result, the solution is to build AI robots for defence operations that can sense, collect data by observing surroundings as any human soldier would, and report it back to a workstation where it can be used for strategy building and planning on what the next step should be during a mission, thus making the army better prepared for any kind of trouble that might be on their way. In this paper, the survey and bibliometric analysis of AI-based IoT managed Swarm Robots from the Scopus repository is discussed, which analyses research by area, notable authors, organizations, funding agencies and countries. Statistical analysis of literature published as journals, articles and papers that aids in understanding the global influence of publication is called Bibliometric analysis. This paper is a thorough analysis of 84 research papers as obtained from the Scopus repository on the 3rd of April 2021. GPS Visualizer, Gephi, wordcloud, and ScienceScape are open source softwares used in the visualization review. As previously mentioned, the visualization assists in a quick and easy interpretation of the different viewpoints in a particular study domain pursuit

    Robots are used today to accomplish many tasks in society, be it in industry, at home, or as helping tools on tragic incidents. The human-robot systems currently developed span a broad variety of applications and are typically very different from one another. The interaction techniques designed for each system are also very different, although some effort has been directed in defining common properties and strategies for guiding human-robot interaction (HRI) development. This work aims to present the state-of-the-art in teleoperation interaction techniques between robots and their users. By presenting potentially useful design models and motivating discussions on topics to which the research community has been paying little attention lately, we also suggest solutions to some of the design and operational problems being faced in this area

    Simulation-Based Countermeasures Towards Accident Prevention : Virtual Reality Utilization in Industrial Processes and Activities

    Get PDF
    Despite growing industrial interests in fully immersive virtual reality (VR) applications for safety countermeasures, there is scanty research on the subject in the context of accident prevention during manufacturing processes and plant maintenance activities. This dissertation aims to explore and experiment with VR for accident prevention by targeting three workplace safety countermeasures: fire evacuation drills, hazard identification and risk assessments (HIRA), and emergency preparedness and response (EPR) procedures. Drawing on the virtual reality accident causation model (VR-ACM) (i.e., 3D modelling and simulation, accident causation, and safety drills) and the fire evacuation training model, two industrial 3D simulation models were utilized for the immersive assessment and training. These were a lithium-ion battery (LIB) manufacturing factory and a gas power plant (GPP). In total, five studies (publications) were designed to demonstrate the potential of VR in accident prevention during the manufacturing processes and maintenance activities at the facility conceptual stages. Two studies were with the LIB factory simulation to identify inherent hazards and assess risks for redesigning the factory to ensure workplace safety compliance. The other three studies constituted fire hazard identifications, emergency evacuations and hazard control/mitigations during the maintenance activity in the GPP simulation. Both study models incorporated several participants individually immersed in the virtual realm to experience the accident phenomena intuitively. These participants provided feedback for assessing the research objectives. Results of the studies indicated that several inherent hazards in the LIB factory were identified and controlled/mitigated. Secondly, the GPP experiment results suggested that although the maintenance activity in the virtual realm increased the perception of presence, a statistically significant delay was recorded at the pre-movement stage due to the lack of situational safety awareness. Overall, the study demonstrates that participants immersed in a VR plant maintenance activity and manufacturing factory process simulation environments can experience real-time emergency scenarios and conditions necessary for implementing the essential safety countermeasures to prevent accidents.Vaikka kiinnostus virtuaalitodellisuuden (VR) kÀyttöön turvallisuuden varotoimissa teollisuudessa on kasvanut, tutkimuksia ei ole juurikaan tehty onnettomuuksien ehkÀisystÀ valmistus- ja kunnossapitotoiminnassa. TÀmÀn vÀitöskirjan tavoitteena on tutkia ja kokeilla VR:ÀÀ tapaturmien ehkÀisyssÀ kohdistuen kolmeen työpaikan turvallisuuden varotoimeen: paloharjoitukset, riskien arvioinnit sekÀ hÀtÀtilanteiden valmiusmenettelyt ja toimintasuunnitelmat (EPR). Kokemuksellisessa ja uppouttavassa koulutuksessa hyödynnettiin kahta teollisuuden 3D-simulointimallia, jotka nojautuvat virtuaalitodellisuuden onnettomuuksien aiheutumismalliin (VR-ACM) (eli 3D-mallinnus- ja simulointi, onnettomuussyy- ja turvallisuuskoulutus) sekÀ paloharjoitusmalliin. NÀmÀ 3D-simulointimallit ovat litiuminoniakkuja (LIB) valmistava tehdas, joka rakennettiin Visual Components 3D-simulointiohjelmistolla (versio 4.0) ja kaasuvoimala (GPP) Unrealin reaaliaikaisella pelimoottorilla (versio 4.2). YhteensÀ viisi tutkimusta (julkaisua) suunniteltiin havainnollistamaan VR:n potentiaalia tapaturmien ehkÀisyssÀ valmistusprosessin layout-suunnittelun ja tehtaan konseptivaiheissa tehtÀvÀn kunnossapidon aikana. Kaksi tutkimusta tehtiin LIB-tehdassimulaatiolla vaarojen tunnistamiseksi sekÀ riskien arvioimiseksi. Tutkimukset tehtiin tehtaan uudelleensuunnittelua varten, työturvallisuuden noudattamisen varmistamiseksi. Muut kolme tutkimusta kÀsittelevÀt palovaaran tunnistamista, hÀtÀevakuointia ja riskien vÀhentÀmistÀ huoltotoiminnan aikana GPP-simulaatiossa. Molemmissa tutkimusmalleissa oli useita virtuaalimaailmaan uppoutuneita osallistujia, jotka saivat kokea onnettomuudet yksilöllisesti ja intuitiivisesti. Osallistujat antoivat palautetta kokeen jÀlkeisessÀ kyselyssÀ. Kyselyn tuloksien avulla LIB-tehtaassa tunnistettiin ja lievennettiin useita vaaroja. GPP-kokeilun tulokset viittasivat siihen, ettÀ vaikka yllÀpitotoiminta virtuaalimaailmassa lisÀsi telelÀsnÀoloa, tilastollisesti merkittÀvÀ viive kirjattiin liikettÀ edeltÀvÀssÀ vaiheessa turvallisuustietoisuuden puuteen vuoksi. Kaiken kaikkiaan tutkimus osoittaa, ettÀ VR-laitoksen kunnossapitotoimintaan ja tuotantotehtaan prosessisimulaatioympÀristöihin uppoutuvat osallistujat voivat kokea reaaliaikaisia hÀtÀskenaarioita ja olosuhteita, jotka ovat vÀlttÀmÀttömiÀ olennaisten turvallisuustoimien toteuttamiseksi.fi=vertaisarvioitu|en=peerReviewed

    This dissertation aims to provide recommendations for addressing marine plastic litter in the ‘New Balis’ of Indonesia sustainably through technological interventions in the framework of the National Action Plan for Marine Litter Management 2018-2025. ‘New Balis’ are the 10 prioritized tourism destinations in Indonesia to be developed and promoted. The ‘New Balis’ development is a national strategic project to boost national income from tourism sector which have been directed by Indonesian President since 2015. This is because tourism is a rapidly growing economic sector in Indonesia. However, ‘New Balis’ are also facing a global challenge called marine plastic litter. Marine plastic litter is a threat to ‘New Balis’ due to has potential impacts on the reduction of marine environment sustainability, health of tourists and local communities as well as tourism business income. Since 2018, Indonesian government has established and promulgated the National Plan of Action on Marine Litter Management 2018-2025. This national plan consists of three important key aspects of interventions (i.e. societal effort, technological application and institutional coordination) and five strategies for addressing marine litter in Indonesia, in particular to manage 70% of marine plastic litter by 2025. The strategies include 1) National movement for raising awareness of stakeholders, 2) Land-based litter management, 3) Litter management at sea and coasts, 4) Funding mechanism, institutional strengthening, monitoring and law enforcement, and 5) Research and development. In this dissertation research, technological interventions around the world and in Indonesia are reviewed and analyzed on their relevance to the national action plan as well as the strengths, weaknesses, opportunities and threats (SWOT) of potential impacts after intervening the technologies in the ‘New Balis’. In order to ensure technological interventions will be sustainable for addressing marine plastic litter in the ‘New Balis’, the aspects of sustainable tourism and international partnerships are also recommended to be considered by Indonesian government and related stakeholders
