Research ArticleOpen accessPhrase in the titleKinematic and Dynamic Analysis of a Classic, Three-Axis Manual Gearbox, Without a Direct SocketRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuFixed axis mechanical transmissions today have the largest spread on the entire planet, being practically used in almost all areas. From the gearboxes of the vehicles to the stationary reducers, used in the electrical, electronic and electro technical equipment, in the heavy industry but also in the light industry, in energy and in transport, practically the transmissions with fixed axes … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 24 May 2020 · 7,673 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleObject Exploration Using a Three-Axis Tactile Sensing InformationS. C. Abdullah, Jiro Wada, Masahiro Ohka, Hanafiah YussofProblem statement: To advance the robust object recognition of robots, we present an algorithm for object exploration based on three-axis tactile data that is necessary and sufficient for the evaluation of contact phenomena. Approach: The object surface contour is acquired by controlling the finger position so that the normal force, measured by optical three-axis tactile sensors, remains constant as two … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 7,313 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleSensorization of Robotic Hand Using Optical Three-Axis Tactile Sensor: Evaluation with Grasping and Twisting MotionsHanafiah Yussof, Jiro Wada, Masahiro OhkaProblem statement: Sensitization of robot hand is still remaining as crucial issue since most of robot hand systems nowadays are only capable to grasp a predefined specific object. It is still difficult for robot hand system to realize human-like tactile sensation. Some common problems in robot hand system are low accuracy sensing device, sensors are not robust enough for long … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,846 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomating a Festo Manufacturing Machine with an Allen-Bradley PLCPraneel Chand, Joven SepulvedaIndustry equipment such as machinery utilising Programmable Logic Controllers (PLCs) become outdated and obsolete over time. Support for older machines and controllers becomes limited and they become incompatible with new computer operating systems. In the end, they are no longer used by industry. However, obsolete machines can be refurbished and used for teaching or demonstration purposes. Hence, this study presents … …Journal of Mechatronics and Robotics, Vol. 5, Issue 1 · 26 Nov 2021 · 7,047 accessesView PDFCite
Research ArticleOpen accessIn the abstractSwitching from Flat to Spatial Motion to 3R Mechatronic SystemsRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuThe anthropomorphic robots are part of the classical series of mechatronic systems, being in the form of arms and having at least three space rotation, to which other components may eventually be added, thus lengthening the entire kinematic chain. You can also add all the planetary or spatial rotating arms or others that are translating. At the end we always … …Journal of Mechatronics and Robotics, Vol. 2, Issue 1 · 22 Jan 2018 · 7,427 accessesView PDFCite
Research ArticleOpen accessIn the abstractCurrent Stage in the Field of Mechanisms with Gears and RodsRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.The development and diversification of machines and mechanisms with applications in all fields require new scientific researches for the systematization and improvement of existing mechanical systems by creating new mechanisms adapted to modern requirements, which involve increasingly complex topological structures. The modern industry, the practice of designing and building machinery is increasingly based on the results of scientific and applied … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 13 Dec 2017 · 6,846 accessesView PDFCite
Research ArticleOpen accessIn the abstractUnderstanding Hybrid Additive Manufacturing of Functional DevicesSantosh Kumar Parupelli, Salil DesaiThe fabrication of electronic components in three-dimensional space is critical for building multifunctional devices. Traditional manufacturing approaches are limited to building planar device configurations. In order to address this limitation, our group has developed a novel hybrid additive manufacturing process that can deposit multi-material patterns on conformal substrates. This direct-write approach involves the combination of microextrusion, pico jet and laser … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 20 Mar 2017 · 8,154 accessesView PDFCite
Research ArticleOpen accessIn the abstractVelocities and Accelerations at the 3R Mechatronic SystemsRelly Victoria V. Petrescu, Raffaella Aversa, Bilal Akash et al.This article presents an original method to determine the speeds and accelerations to structures MP R-3 The structure of the 3R (space) are known (required) rotation speeds of the triggers and must be determined speeds and accelerations of the endeffector M. Starting from the positions of direct kinematic system MP R-3deriving these system of relations in depending on the time, … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 20 Mar 2017 · 7,963 accessesView PDFCite
Research ArticleOpen accessIn the abstractThree Dimensional Reconstruction of Human Heart Surface from Single Image-View Under Different Illumination ConditionsAqeel Al-Surmi, Rahmita Wirza, Mohd Zamrin Dimon et al.The 3D reconstruction from a single-view image is a longstanding issue in computer vision literature, especially in the medical field. Traditional medical imaging techniques that provide information about the heart and which are used to reconstruct the heart model, include Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) images. However, in some cases, they are not available and the applications … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 17 Jun 2013 · 7,613 accessesView PDFCite
Research ArticleOpen accessIn the abstractDemotivating Factors for English Language Learning Among University StudentsReyhaneh Ghadirzadeh, Fariba Pourabolfathe Hashtroudi, Omid ShokriProblem statement: Demotivation is a relatively new issue in the field of second/foreign Language (L2) learning motivation. Recognizing and removing barriers can have a marked effect on motivation and attention to learning in general and ESL/EFL learning in particular. Demotivating factors are essential factors which negatively influence the learner’s attitudes and behaviors and hence lead to undesired learning outcomes.
