    Physarum polycephalum -limasienen Gaiatarina : Uusmaterialistista ja posthumanistista algoritmitutkimusta sekÀ vitaalista elÀmÀÀ

    Get PDF
    Gaiatarina limasienelle on toislajisen, mediaympĂ€ristössĂ€ vaikuttavan limasienen tarina. SiinĂ€ kartoitetaan Physarum polycephalum –perustaista biologista ohjelmointia ihmistieteisestĂ€ nĂ€kökulmasta. Tarkastelen tĂ€mĂ€n organismin panosta luovana kanssa-ajattelijana niin koodauksessa, kuin biotaiteessakin. Aineistoikseni valitsin limasienen kumppaneita, jotka kokevat organismin luovana ja Ă€lykkÀÀnĂ€, ja purkavat molemmat työnsĂ€ avulla ihmisen rationaliteetille annettua ylivaltaa muihin lajeihin nĂ€hden. Latourilainen tieteentutkimuksellinen ote sekoittuu taiteentutkimukseen. Tiede ja taide asettautuvat samalle tasolle. Molemmat osallistuvat tuottamaan tietoa ja ymmĂ€rrystĂ€ ja uutta maailmaa toislajisen kanssa. Tutkielma tĂ€htÀÀ ymmĂ€rtĂ€mÀÀn vitaalista ainetta ja koodia posthumanistisessa ja uusmaterialistisessa kehikossa tarjoten ihmisen, koodin ja limasienen verkostoon ihmiskeskeisyyttĂ€ purkavaa nĂ€kökulmaa. Apuna argumentoinnissa kulkee Taina Bucherin (2016) suhteellinen ja materiaalinen algoritmitutkimus, sekĂ€ Jussi Parikan (2010) ”elĂ€imellinen” media-arkeologia. Teoreettinen viitekehys pohjautuu Gilles Deleuzen uusmaterialismiin, jonka ontologinen perusta on alituisen muutoksen prosesseissa. Tutkielma jakautuu limasienen elinkaaren mukaan plasmoodioon, sklerootioon ja sporangioon. Jokaisessa luvussa pyritÀÀn tuomaan esiin Physarum polycephalumin materiaalinen erityisyys ja osallisuus verkostoissa.Gaiastrory for slime mould focuses in the influential nonhuman actor of media environment. It maps the Physarum polycephalum –based programming from humanities point of view. I study the active participation of slime mould as creative co-thinker in coding and bio art. My cases seek to show how collaboration between human and nonhuman can discharge human exceptionality by seeing the creativity emerging within collision and not limited to human capacities to produce ideas. Latourian science studies is blended with art studies. Both art and science are settling to produce knowledge with nonhuman earth other. I seek to understand both vital matter and code in posthumanist and new materialist frame offering post-anthropocentric interpretation on media environment. Relational and material algorithm studies of Taina Bucher (2016) and “bestial” media archaeology of Jussi Parikka (2010) are paving the way for the argumentation. Theoretical framework leans thoroughly on the process philosophy and ontology of difference offered by philosopher Gilles Deleuze

    Opinions and Outlooks on Morphological Computation

    Morphological Computation is based on the observation that biological systems seem to carry out relevant computations with their morphology (physical body) in order to successfully interact with their environments. This can be observed in a whole range of systems and at many different scales. It has been studied in animals – e.g., while running, the functionality of coping with impact and slight unevenness in the ground is "delivered" by the shape of the legs and the damped elasticity of the muscle-tendon system – and plants, but it has also been observed at the cellular and even at the molecular level – as seen, for example, in spontaneous self-assembly. The concept of morphological computation has served as an inspirational resource to build bio-inspired robots, design novel approaches for support systems in health care, implement computation with natural systems, but also in art and architecture. As a consequence, the field is highly interdisciplinary, which is also nicely reflected in the wide range of authors that are featured in this e-book. We have contributions from robotics, mechanical engineering, health, architecture, biology, philosophy, and others

    Emergence of self-organized amoeboid movement in a multi-agent approximation of Physarum polycephalum

    Get PDF
    The giant single-celled slime mould Physarum polycephalum exhibits complex morphological adaptation and amoeboid movement as it forages for food and may be seen as a minimal example of complex robotic behaviour. Swarm computation has previously been used to explore how spatio-temporal complexity can emerge from, and be distributed within, simple component parts and their interactions. Using a particle-based swarm approach we explore the question of how to generate collective amoeboid movement from simple non-oscillatory component parts in a model of P. polycephalum. The model collective behaves as a cohesive and deformable virtual material, approximating the local coupling within the plasmodium matrix. The collective generates de-novo and complex oscillatory patterns from simple local interactions. The origin of this motor behaviour distributed within the collective rendering is morphologically adaptive, amenable to external influence and robust to simulated environmental insult. We show how to gain external influence over the collective movement by simulated chemo-attraction (pulling towards nutrient stimuli) and simulated light irradiation hazards (pushing from stimuli). The amorphous and distributed properties of the collective are demonstrated by cleaving it into two independent entities and fusing two separate entities to form a single device, thus enabling it to traverse narrow, separate or tortuous paths. We conclude by summarizing the contribution of the model to swarm-based robotics and soft-bodied modular robotics and discuss the future potential of such material approaches to the field. © 2012 IOP Publishing Ltd

    Fluid-filled Soft-bodied Amoeboid Robot Inspired by Plasmodium of True Slime Mold

    This paper presents a fluid-filled soft-bodied amoeboid robot inspired by plasmodium of true slime mold. The significant features of this robot are twofold: (1) the robot has fluid circuit (i.e., cylinders and nylon tubes filled with fluid) and truly soft and deformable body stemming from Real-time Tunable Springs (RTSs), the former seals protoplasm to induce global physical interaction between the body parts and the latter is used for elastic actuators; and (2) a fully decentralized control using coupled oscillators with completely local sensory feedback mechanism is realized by exploiting the global physical interaction between the body parts stemming from the fluid circuit. The experimental results show that this robot exhibits adaptive locomotion without relying on any hierarchical structure. The results obtained are expected to shed new light on design scheme for autonomous decentralized control systems
