Vision-Based Robotic Arm Control Algorithm Using Deep Reinforcement Learning for Autonomous Objects Grasping

While working side-by-side, humans and robots complete each other nowadays, and we may say that they work hand in hand. This study aims to evolve the grasping task by reaching the intended object based on deep reinforcement learning. Thereby, in this paper, we propose a deep deterministic policy gradient approach that can be applied to a numerous-degrees-of-freedom robotic arm towards autonomous objects grasping according to their classification and a given task. In this study, this approach is realized by a five-degrees-of-freedom robotic arm that reaches the targeted object using the inverse kinematics method. You Only Look Once v5 is employed for object detection, and backward projection is used to detect the three-dimensional position of the target. After computing the angles of the joints at the detected position by inverse kinematics, the robot’s arm is moved towards the target object’s emplacement thanks to the algorithm. Our approach provides a neural inverse kinematics solution that increases overall performance, and its simulation results reveal its advantages compared to the traditional one. The robot’s end grip joint can reach the targeted location by calculating the angle of every joint with an acceptable range of error. However, the accuracy of the angle and the posture are satisfied. Experiments reveal the performance of our proposal compared to the state-of-the-art approaches in vision-based grasp tasks. This is a new approach to grasp an object by referring to inverse kinematics. This method is not only easier than the standard one but is also more meaningful for multi-degrees of freedom robots.

Design Of 4DOF 3D Robotic Arm to Separate the Objects Using a Camera

Nowadays robotic arm is widely used in various industries, especially those engaged in manufacturing. Robotic arms are usually used to perform jobs such as picking up and moving goods from their place of origin to the location desired by the operator. In this study, a 3d 4 DOF (Degree of Freedom) robotic arm. The prototype was made to move goods with random coordinates to places or boxes whose coordinates were determined in advance. The robot can know the coordinates of the object to be taken or moved. The arm robot prototype design is completed with a camera connected to a computer, where the camera is installed statically (fixed position) above the robot's work area. The camera functions like image processing to detect the object's position by taking the coordinates of the object. Then the object coordinates will be input into inverse kinematics that will produce an angle in every point of the servo arm so that the position of the end effector on the robot arm can be founded and reach the intended object. From the results of testing and analysis, it was found that the error in the webcam test to detect object coordinates was 2.58%, the error in the servo motion test was 12.68%, and the error in the inverse kinematics test was 7.85% on the x-axis, the error was 6.31% on the y-axis and an error of 12.77% on the z-axis. The reliability of the whole system is 66.66%.

The Aporetics of Temporality and the Poetics of the Will

The aporias of time that Paul Ricœur identifies in the conclusion to his three-volume Time and Narrative offer a fecund starting-point from which to consider how the poetics of narrativity figures in a philosophy of the will. By setting the poetics of narrativity against the aporetics of temporality, Ricoeur highlights the narrative art’s operative power in drawing together incidents and events in answer to time’s dispersion across the present, the past, and the future. In turn, the confession of the limits of narrative opens the way to a broader consideration of the idea of the unity of history in the absence of a meta-historical plot. This idea calls for a reflection on the ethical and political imperative of making freedom a reality for all. By taking the theory of freedom’s actualization as a touchstone, I argue that the vision of a reconciled humanity that for Ricœur is the intended object of the poetics of the will acquires the force of a directive idea. The capacity to refashion the real from within thus proves to be decisive for drawing out the connection between the aporetics of temporality, the poetics of narrativity, and Ricœur’s philosophical anthropology.

LPKF-LDS technology for the production of three-dimensional schemes on plastics

A promising technology for the production of three-dimensional circuits on plastics, the scope of its current application and prospects for its further development in the radio-electronic industry are considered. The analysis of current opportunities and limitations is carried out. It is shown that the key component of the technology is the correct choice of thermoplastics with suitable characteristics for the intended object, taking into account the resistance to external factors. An analysis of the international and domestic regulatory framework for thermoplastics was conducted. This allowed to determine the key characteristics for 3D-MID-technology and to make a comparison. A classification is proposed on the basis of the key characteristics of thermoplastics for making a decision when choosing materials on the market, taking into account the application in the radio-electronic industry using 3D-MID technology, which is currently either absent or not fully represented. Methods of testing materials for use in the production technology of three-dimensional circuits on plastics and ensuring the quality of manufacturing of radio engineering products, allowing to confirm the compliance of key parameters of materials are studied. The article considers the order of the build process with the application of the LPKF-LDS technology production of three-dimensional circuits on plastics, which allows building a sequence of processes with particular implementation as an example. The considered LPKF-LDS technology as part of the 3D-MID line is planned in the new laboratory “Threedimensional circuits on plastics and flexible media” at the Department of Design and Production of Radioelectronic Devices of the Institute of Radio Engineering and Telecommunications Systems of MIREA – Russian Technological University.

An Analytical Study of Ideally Inherent Operative Transformation of the Original Mental Process in Edmund Husserl’s Phenomenology

This research paper entitled “An Analytical Study of Ideally inherent Operative Transformations of the Original Mental Process in Edmund Husserl’s Phenomenology” has three objectives: 1) to study the mental process of reflection and modification in which that mind is directed towards the intended object including the mental objects regarding Western philosophical thought, Edmund Husserl, 2) to study of the way to operative transformation of original mental process and, 3) to analyze various forms of transformed reproduction and a problem of the reproduction. It is found that the transformation of the original mental process in Edmund Husserl’s phenomenology is the ideally inherent process of reproduction of mental process in which the mental process passed through the modificative process together with its contents so as to produce a novel knowledge. The transformative process as such is systematically operated with main following aspects: (1) The mode of giveness (the immanent essence of a concrete sensation-content such as a visual sensation-content in the field of visual sensation-Data that is continually adumbrated from the visual physical objects), (2) the temporal mental processes are to be unified as one stream of mental process, (3) the phase or the temporal horizon which is cosmic time in other ways such as horizon of Now, horizon of Before, and horizon of After, and (4) pure ego, the function of which is to direct its regards to the temporal modes of giveness (immanent essences). By its transformative operation, it is effectively proceeded with three steps. The first is a step of a physical perception of the mental process in which the perceived physical things is used as an essential content for all mental process as they are kept in a memory. The second step is succeeded from the first step which is called a retention or a primary memory; the process of a modification using the immanent object kept in a retention as the initial part of the constitution of an identical object. Then, comes the third step which is the step of a recollection or a second memory; it is to recall the remembered or represented for the perception again. After the whole process has fully accomplished, the remembered or represented is afresh reproduced. However, the reproduction of the remembered or the represented can emerge with two possibilities; one is the vague-reproduced information as without repeating while looking at the reproduced flash; other is afresh one as it is repeated resulting in further perception. However, the reproduction of the remembered can be accurate and perfect depending on two conditions; one is the condition of the perception of physical things and the condition of either clarity or obscurity of the whole object that is re-presented with the mode of mental process.

Shared multisensory sexual arousal in virtual reality (VR) environments

This research explores multisensory sexual arousal in men and women, and how it can be implemented and shared between multiple individuals in Virtual Reality (VR). This is achieved through the stimulation of human senses with immersive technology including visual, olfactory, auditory, and haptic triggers. Participants are invited to VR to test various sensory triggers and assess them as sexually arousing or not. A literature review on VR experiments related to sexuality, the concepts of perception and multisensory experiments, and data collected from self-reports was used to conclude. The goal of this research is to establish that sexual arousal is a multisensory event that may or may not be linked to the presence or thought of the intended object of desire (sexual partner). By examining what stimulates arousal, we better understand the multisensory capacity of humans, leading not only to richer sexual experiences but also to the further development of wearable sextech products, soft robotics, and multisensory learning machines. This understanding helps with other research related to human-robot interaction, affection, detection, and transmission in both physical and virtual realities, and how VR technology can help to design a new generation of sex robots.

Förskollärares konstruktion av ett fysikaliskt lärandeobjekt

In 2010 the Swedish national curriculum was revised and learning goals concerning chemistry and physics were introduced. That has induced a need for further understanding of teaching and learning of specific content in preschool. Focus in this article is how physics content is constructed as an object of learning during preschool teachers’ planning of teaching. The result of a phenomenographic analysis focusing themes of the conversation concerning the intended object of learning reveals a complex process. Occurrences in the activities with the children, available tools at the preschool, the preschool teachers’ perceptions of the mission and understanding of the learning object, contribute to the construction of the learning object. All these aspects are discussed and implications for preschool practice are suggested.
