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.

Research ArticleOpen accessIn the keywordsGeometry and Determining the Positions of a Plan Transporter ManipulatorRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.The conveyor mechanism (working in a plan) to be presented in this study is a classic case of manipulating conveyor, simply with a single degree of mobility. It is a very common mechanism used in classical mechanics, being encountered at lifting platforms, at handicapped chairs, at cranes, forklifts, automatic machines and machines, or at older steam locomotives where it having … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 1 Jan 2018 · 6,557 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 · 7,788 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 · 6,267 accessesView PDFCite
Research ArticleOpen accessIn the keywordsKinematic 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 · 7,685 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 · 6,313 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPresents the Dynamics at a Basic Anthropomorphic RobotRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuSerial robots are the most used today and among them, the most common is the basic 3R module, the module that is developed in the vast majority of anthropomorphic serial industrial robots, which today occupies at least 80-90% of the total industrial robots existing worldwide. One studied the kinematics and the forces in this module in other works, with an … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 5 May 2020 · 7,187 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 · 6,955 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAbout Aircraft's New Power and PropulsionRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuEven though the current classical methods of aerospace propulsion are much improved, some of the most modern methods have already been introduced, including propulsion with electric motors. Energy can be obtained from hydrogen burners, honeycomb burners to protect the combustion of hydrogen that burns 10 times faster than conventional fuels or alcohols. Hydrogen storage is also done in honeycomb cell … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 5 Mar 2020 · 7,329 accessesView PDFCite
