Innovative Collaborative Method for Interaction between a Human Operator and Robotic Manipulator Using Pointing Gestures

The concept of “Industry 4.0” relies heavily on the utilization of collaborative robotic applications. As a result, the need for an effective, natural, and ergonomic interface arises, as more workers will be required to work with robots. Designing and implementing natural forms of human–robot interaction (HRI) is key to ensuring efficient and productive collaboration between humans and robots. This paper presents a gestural framework for controlling a collaborative robotic manipulator using pointing gestures. The core principle lies in the ability of the user to send the robot’s end effector to the location towards, which he points to by his hand. The main idea is derived from the concept of so-called “linear HRI”. The framework utilizes a collaborative robotic arm UR5e and the state-of-the-art human body tracking sensor Leap Motion. The user is not required to wear any equipment. The paper describes the overview of the framework’s core method and provides the necessary mathematical background. An experimental evaluation of the method is provided, and the main influencing factors are identified. A unique robotic collaborative workspace called Complex Collaborative HRI Workplace (COCOHRIP) was designed around the gestural framework to evaluate the method and provide the basis for the future development of HRI applications.

Sign To Text Conversion- Helping Aid

The ancient way of sign language is most natural forms of communication. The recognition of sign is place a key role in research field. The development and improvement on this kind of work need more and more new techniques to analyze the accurate results. Many people don't know it and interpreters are hard to come by, we developed a real-time technique for finger spelling-based American Sign Language using neural networks. In our technique, the hand is first sent through a filter, and then it is passed through a classifier, which analyses the class of hand movements. For each alphabet the proposed model has a 96 percent accuracy rate. This model mainly implemented for Dumb and Deaf people for communication.

The system of objective economic laws in the realities of systematic-subjective economic lawlessness

The article reveals the differences of systemic action of the laws of the social form of material world from the action of the laws determining the motion of the four natural forms of matter. The author shows the difference between the consequences of violating natural and social laws. The meaningful understanding of the category "economic law" is deepened and the general list of the system of objective economic laws is specified. The author structurizes the main classification groups of laws, which are united based on the most typical features. According to the criteria of system weight, as well as essential content and spatio-temporal coordinates of the regulatory action, four block-type groups of laws are distinguished. The author singles out differentiated subgroups of laws, which are united by six system-specific features. The article shows the destructive nature of "scientific" dogmas of financial-and-debt "liberal-monetarism". Revealed the encouraging motivation that determines the dominant behavior of the current global monopoly capital, which is aimed at destroying the systemic action of the mechanisms of the laws of market economy. In particular, the author shows the ways of destruction of the mechanism of action of the law of value and laws of money circulation which provide the equivalent character of commodity production and exchange. Displayed specific manifestations of systemic and subjective lawlessness prevailing in the system of monetary and financial-debt relations at the global and national-state levels. The author assesses the consequences of financial and credit expansion for countries with different development levels in the capitalist mode of production leading to suffocation of national economies by the international monopolies by forming an unbearable burden of servicing foreign borrowings and withdrawal of invaluable land and other natural resources into private ownership of global corporate-monopolistic creditors.

Natural and Geomorphological Response of the Small Lowland River Valley for Anthropogenic Transformation

The regulation of small rivers and the consequent maintenance works are common in the Central European Lowlands. This article attempts to determine the relationship between the invertebrate fauna (and consequently the biocenosis) of the small lowland river valley and its landforms (morphodynamics) under the conditions of very large and rapid changes caused by river regulation and maintenance. On this basis, an attempt to analyze the response of the ecosystem to rapid transformations associated with engineering works was made. The study covered Kraska, a small river typical for Polish Lowlands, which has been regulated along almost the entire length. The results showed that, in the regulated sections, where the natural forms of the relief were destroyed, there were significantly fewer taxa and significantly smaller numbers of the specimen. Despite the clear negative impact of the regulatory work on the ecosystem, the river in some sections showed the ability to spontaneously restore certain geomorphic features.

EKSPRESI PHILIP RICARDO BIJI TERHADAP MASYARAKAT DI SABAH MELALUI ARCA ‘TANPA TAJUK’

Kajian ini menjalankan analisis terhadap karya arca Philip Ricardo Biji berjudul ‘Tanpa Tajuk’ untuk menyingkap ekspresi pengarca terhadap masyarakat di Sabah. Data-data pemerhatian terhadap bentuk dan makna arca dianalisis melalui gabungan teori Ikonografi oleh Erwin Panofsky dan teori kritikan psikoanalisis oleh Sigmund Freud. Teori ikonografi terbahagi kepada tiga tahap. Kajian ini mendapati bahawa arca Philip Ricardo Biji mempunyai ekspresi yang menyerap ke dalam perasaan masyarakat di Sabah. Representasi bentuk semula jadi yang dipaparkan adalah imej manusia, sungai dan tahi lalat. Imej-imej tersebut menggambarkan motif pada anyaman dan tatu etnik Murut di Sabah. Motif-motif yang dipaparkan merujuk makna tentang budaya masyarakat Murut yang sedang bermesyuarat, acara minum tapai, aktiviti di sungai dan kepercayaan tentang keselamatan dari serangan buaya. Dari segi kritikan psikoanalisis pula, penghasilan arca seramik lebih menekankan kepada makna tersirat yang menggambarkan pengalamannya sebagai pelukis, pendidik dan ahli kraf serta aktiviti sosialnya bersama masyarakat etnik Murut. Arca ‘Tanpa Tajuk’ oleh Philip Ricardo Biji memaparkan ekspresi dari segi pemikiran, perlakuan dan perasaannya terhadap masyarakat Murut di Sabah. The purpose of this study is to analyze Philip Ricardo Biji’s sculpture entitled ‘Tanpa Tajuk’ in order to ascertain the sculptor’s perception toward the Sabah culture. Observational data on the form and context of sculptures were examined using a combination of Erwin Panofsky’s Iconographic theory and Sigmund Freud’s psychoanalytic criticism theory. Three stages of iconographic theory occur. This research found that Philip Ricardo Biji’s sculpture carries an expression that resonates with the community’s emotions in Sabah. People, rivers and moles are all depicted as natural forms. The illustrations depict motifs found on Murut ethnic weavings and tattoos in Sabah. The motifs depicted are symbolic of the Murut society’s culture, including gatherings, tapai drinking events, river activities and beliefs about crocodile safety. In psychoanalytic critique the development of ceramic sculpture exemplifies the implicit meaning of his experience with the Murut ethnic group as a painter, educator and craftsperson. The sculpture titled ‘Tanpa Tajuk’ by Philip Ricardo Biji expresses his thoughts, behaviour and feelings toward the Murut group in Sabah.

The Art of (Up)Recycling: How Plastic Debris Has Become a Matter of Art?

Since 1907, when Bakelite was invented, there has been a dramatic rise in the daily usage of plastic-like materials. Today, its negative impacts are a part of scientific studies and public debates. Art and artists play a significant role in these discussions. They mediate between the specialist content and public awareness. This study is dedicated to the artworks of artists using plastic waste collected from the seashore. I organized their works into three lines, within which artists have different threads of plastic interference in the natural environment. The artists examine: 1. The future of a planet dominated by plastic products, like Bonita Ely’s work from the Plasticus Progressus series that predict post-human existence. 2. The conceptual metaphors of contemporary culture, presented in Bounty, Pilfered by Pam Longobardi. It is an installation constructed from fishing debris. 3. The “nature-cultural” forms, i.e., organic constructions created by human interference and modified by nature, like Crochet Coral Reefs. The cooperation of volunteers with Margaret and Christine Wertheim produced this artwork. The artistic intervention creates new cultural and natural forms. This kind of artistic attitude towards waste is a formal and aesthetic innovation of various materials used in artistic practices. It also makes a significant commentary about the future of Earth. In a discussion about art producing unnecessary objects, recycling artistic material seems more ethical than using non-renewable materials obtained from natural sources.
