Review ArticleOpen accessIn the keywordsSomething about a Railbound Forging ManipulatorRelly Victoria Virgil PetrescuHeavy payload forging manipulators are mainly characterized by large load output and large capacitive load input. The relationships between outputs and inputs have greatly influenced the control and reliability. Forging manipulators have become more prevalent in the industry today. They are used to manipulate objects to be forged. The most common forging manipulators are moving on a railway to have … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 8 May 2019 · 7,086 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStructural Analysis of Spatial MechanismsFlorian Ion Tiberiu PetrescuThe paper briefly presents how structural analysis is performed on spatial mechanisms, presenting a practical application in the mechatronics of parallel robots, especially in Steward platforms. Structural analysis always helps to better understand the phenomena and especially the way the mechanisms are made. At spatial mechanisms the problems are a little more complex than those raised by plane mechanisms. For … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 26 May 2018 · 7,971 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSome Aspects of the Structure of Planar MechanismsRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.The machine is a technical system made up of distinct kinematic component parts (called kinematic elements) which, following the imprinting of movements imposed on an element or elements (considered as leading elements), cause movements to all other kinematic elements in order to execute a useful mechanical thing, or transforming some form of energy into mechanical energy. It follows from the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 8 Feb 2018 · 8,020 accessesView PDFCite
Review ArticleOpen accessIn the keywordsNanoboticsRelly Victoria Virgil PetrescuNanobotics (or Nanorobotics) is a field of emerging technology that deals with the creation of robots whose components are typically the size of a molecule or nanometer (10-9 meters). More specifically, nanorobotics refers to nanotechnology, an engineering discipline that designs and builds nanorobots that have movement, processing and transmission characteristics, program execution, etc. Nanomachines are largely in the research and … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 19 Jul 2020 · 7,783 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPresents the Kinematics and Forces at a Basic Anthropomorphic RobotRelly Victoria Virgil PetrescuThe basic structure of the anthropomorphic robots used today massively in 80-90% cases from the industrial robots will be presented briefly, with the highlighting of an original method for determining the kinematics of the basic 3R module and with highlighting the forces at the basic structure set in the discussion. Some representative examples of calculation will be remembered as results. … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 14 May 2020 · 6,307 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMachine Motion Equations Presented in a New General FormatNicolae Petrescu, Florian Ion Tiberiu PetrescuConsidering the increased importance of robots nowadays, when no large factory or factory can work without robots, we want to present in the work the motion equations of the machine in an original form, both in terms of aspect and their deduction. The machine's motion equations can be used in dynamic calculations at any type of machine, whether it be … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 22 May 2019 · 6,131 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDynamics at Classical DistributionRelly Victoria Virgil PetrescuClassical distribution is the most used in rigid memory mechanisms adapted to four-stroke internal combustion engines such as Otto or diesel, as it was designed by Otto more than 150 years ago, without essential changes from its conception and up today. Since it was not yet possible to introduce the electric car to the industrial scale and today we have … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 26 Apr 2019 · 6,394 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPresents the Kinematics of a Manipulator with Three MobilitiesRelly Victoria Virgil PetrescuThe paper briefly presents the kinematic study of a manipulator with three mobilities, which can be used both in industrial halls and in garages, depending on its suitably chosen constructive size, which at smaller dimensions can be handled very easily. This manipulator can carry large loads, thus easing the work of the human being and preventing it from major dangers … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 30 May 2020 · 6,262 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPresentation of Four-stroke Engine Design ElementsRelly Victoria Virgil PetrescuHaving escaped the shadow of the global energy crisis by implementing nuclear fission, wind, solar, bioenergy, but also by producing and extracting (deep) gases capable of providing us with planetary reserves for two more. Or at least three thousand years, we have started to relax more energetically, but due to the huge pollution produced by cars, the rules of their … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 28 Apr 2020 · 6,950 accessesView PDFCite
Research ArticleOpen accessIn the keywordsElementary Structure of Matter can be Studied with New Quantum ComputersNicolae Petrescu, Florian Ion Tiberiu PetrescuMuch has been talked about quantum computers. Today they are working on difficult simulations, so we can already congratulate the college of researchers at the Oak Ridge National Laboratory as the world's first to successfully simulate an atomic nucleus using a quantum computer. The results that were published in the physical examination letters demonstrate the huge capacity of quantum systems … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 25 Jun 2018 · 7,698 accessesView PDFCite
