The concept of reconfigurability and its applications in robotics have become prominent in the past few years as they provide versatility, adaptability and scalability to the systems. The reconfigurable robots can perform tasks in outer space, under the sea and in hazardous environments by rearranging their physical configurations to alter the system’s behavior and geometry. However, the concept of reconfigurable robots is not just constrained by the mechanical reconfiguration of the components, for the system should also demonstrate a modular reconfigurable behavior to newly imposed conditions. The objective of this work was to design and implement a multi-modal reconfigurable platform based on the concept of “form follows function” to be integrated with 3D-Immersive telepresence systems. The developed system was analyzed to verify the feasibility and functionality of the proposed architecture, and suggestions were made for future improvements.

The concept of telepresence allows human beings to interact with hazardous environments and situations without facing any actual risks. Examples include the nuclear industry, outer space and underwater operations, mining, bomb disposal and firefighting. Recent progress in digital system technology, especially in technology of reconfigurable logic devices (e.g. FPGA), allows the effective implementation of advanced embedded systems characterized by high-performance data processing and high-bandwidth communication. However, most of the existing telepresence systems do not benefit from these advancements. Therefore, the goal of this work was to develop a concept and architecture of the platform for the 3D-Panoramic Telepresence System for mobile robotic applications based on reconfigurable logic devices. During the development process, two versions of the system were implemented. The first system focused on feasibility testing of major components of the proposed architecture. Based on the experimental results obtained on the first prototype of the system and their analyses, a set of recommendations were derived for an updated version of the system. These recommendations were incorporated into the implementation of the second and final version of the system.

Resumen: Este artículo aborda los modos como las imágenes prefiguran el tiempo por venir, el futuro. En otras palabras, lo que entendemos por el futuro, un tiempo sin historicidad, es articulado en el tiempo presente y corresponde a un paradójico movimiento entre tiempo de nostalgia y tiempo de deseo. Para explorar el tema, abordamos las nociones de profecía y predicción y posteriormente ahondamos en las imágenes técnicas, que son centrales en la producción de la era geológica conocida como Antropoceno. El Antropoceno, en tanto escenario planetario inminente, significa un particular encuentro entre las profecías apocalípticas de las religiones y el pensamiento mítico, y las predicciones catastróficas de las ciencias, derivando en una singular imagen de futuro que pareciera ser un fin y un comienzo a la vez: la conquista del Espacio y la terraformación de otros mundos, donde Marte es una suerte de espejo de la Tierra que proyecta imágenes que son simultáneamente del pasado y del futuro.Palabras Clave: Antropoceno. antropología de la imagen. historicidad.

In other words, what we understand as future, a time devoid of historicity, is articulated in the present and corresponds to a paradoxical movement between nostalgia and desire. To delve into the matter, we explore the notions of prophecy and prediction, then we examine technical images, which are key to the production of the geological era known as the Anthropocene. The Anthropoce, seen as an imminent planetary scenario, implies a remarkable encounter between apocalyptic prophecies, mythical thinking, and scientific catastrophic predictions which condensate in a singular image of the future that speaks of beginnings and ends: the conquest of outer space and the terraforming of other worlds where Mars mirrors the Earth and projects images that belong simultaneously to the past and the future.Keywords: Anthopocene. anthropology of the image. historicity.

Em outras palavras, aquilo que entendemos por futuro, um tempo sem historicidade, é articulado no tempo presente e faz parte de um movimento paradoxal entre o tempo da saudade e o tempo do desejo. Para fazer essa abordagem, partimos das noções de profecia e predição, para compreender as imagens técnicas como elementos centrais da visualidade da era geológica conhecida como Antropoceno. Essa era geológica, em quanto cenário planetario iminente, significa um particular encontro entre as profecias apocalípticas das religões e o pensamiento mítico, e as predições catastróficas das ciências, dando lugar a uma singular imagem do futuro que se propõe como um final e um começão ao mesmo tempo: a conquista do Espaço e a terraformação de outros mundos, onde Marte é um tipo de espelho da Terra, que projeta imagens que são do pasado e do futuro ao mesmo tempo.Palavras-chave: Antropoceno. antropologia das imagens. historicidade.

Modular self-reconfigurable robots present wide and unique solutions for growing demands in the domains of space exploration, automation, consumer products, and so forth. The higher utilization factor and self-healing capabilities are most demanded traits in robotics for real world applications and modular robotics offer better solutions in these perspectives in relation to traditional robotics. The researchers in robotics domain identified various applications and prototyped numerous robotic models while addressing constraints such as homogeneity, reconfigurability, form factor, and power consumption. The diversified nature of various modular robotic solutions proposed for real world applications and utilization of different sensor and actuator interfacing techniques along with physical model optimizations presents implicit challenges to researchers while identifying and visualizing the merits/demerits of various approaches to a solution. This paper attempts to simplify the comparison of various hardware prototypes by providing a brief study on hardware architectures of modular robots capable of self-healing and reconfiguration along with design techniques adopted in modeling robots, interfacing technologies, and so forth over the past 25 years.

Although the empiric paradigm is now dominant in academic research, in Japan quite a few psychiatric clinicians still take phenomenological-anthropological approaches into consideration, especially when they address manic-depressive illness with typical endogenous features. This is because Shimoda's concept of “shuuchaku-kishitsu” (statothymia) has been widely accepted, together with other phenomenological views of continental origin. In the present paper the author first delineates Shimoda's concept which is based on observations of patients' personality features and the characteristics of their emotionality. He then attempts to refine this concept in spatiotemporal terms, presenting the view that in patients the past self tends to adhere to the present self (the term “shuuchaku” means “adhering to” or “preoccupied with”). He also considers that patients tend to incorporate “soto” (outer space) into “uchi” (inner space), where they believe that symbiotic relations are preserved. Finally, he argues the clinical significance of the presented views in the cultural milieu in which Japanese psychiatric practices are situated.

Long-term travel and lengthy stays for astronauts in outer space are imminent. To date, more than 500 astronauts have experienced the extreme conditions of space flight including microgravity and radiation. For the past decade, many studies associated with long-duration spaceflight have shown the recurring occurrence of ophthalmic abnormalities. The reasons of the observed changes in some astronauts remained unclear. However, factors such as the increase in intracranial pressure and fluid shifts are among the top potential contributing elements.

Mobile robots working in special environment have to adapt for unknown and complex environment characteristics, so high mobility, functional versatility and robustness of mobile robots are required. Different from specialized robot designed for single function in single environment, single unit of modular reconfigurable robots has simple mechanical structure, flexible movement and maneuverability; meanwhile, the combination of multiple units has flexible and versatile configuration, combined with distributed control and swarm intelligence algorithm to gain environmental adaptability and functional versatility of the entire reconfigurable robot system. Single unit of modular mobile reconfigurable robots could complete lightweight tasks such as transporting medicines, distributing and accompanying nurses. Meanwhile, the combination of multiple units could complete heavyweight tasks such as transporting patients and large medical equipment. Modular mobile reconfigurable robot system has broad application prospects in the field of medical auxiliary robots.

AbstractPassive radiative cooling, drawing heat energy of objects to the cold outer space through the atmospheric transparent window, is significant for reducing the energy consumption of buildings. Daytime and nighttime radiative cooling have been extensively investigated in the past. However, radiative cooling which can continuously regulate its cooling temperature, like a valve, according to human need is rarely reported. In this study, we propose a reconfigurable photonic structure, based on the effective medium theory and semi-analytical calculations, for the adaptive radiative cooling by continuous variation of the emission spectra in the atmospheric window. This is realized by the deformation of a one-dimensional polydimethylsiloxane (PDMS) grating and nanoparticle-embedded PDMS thin film when subjected to mechanical stress/strain. The proposed structure reaches different stagnation temperatures under certain strains. A dynamic tuning in emissivity under different strains results in a continuously variable “ON”/“OFF” mode in a particular atmospheric window that corresponds to the deformation-induced fluctuation of the operating temperatures of the reconfigurable nanophotonic structure.
