Review ArticleOpen accessThe TESS Satellite will Search for Planets in the Vicinity of our Solar SystemRelly Victoria Virgil PetrescuThe US Space Agency has launched from Cape Canaveral, Florida, the TESS satellite, which will search for planets near our solar system and study them in detail. "TESS will significantly increase the number of planets studied," said George Ricker of the Massachusetts Institute of Technology, MIT, before launching. "It will double the number of planets we've seen and detected with … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 23 May 2019 · 6,639 accessesView PDF Cite

Review ArticleOpen accessSpace ProbesRelly Victoria Virgil PetrescuA space probe is an unmanned space vehicle launched into space to study more or less distant different celestial objects: The Sun, the planets, dwarf planets and small bodies, their satellites, the interplanetary medium or the interstellar medium. A space probe is distinguished from other unmanned spacecraft that remain in Earth orbit. Space probes can take a large number of … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 21 May 2019 · 7,407 accessesView PDF Cite

Research ArticleOpen accessContributions to the Synthesis of Fixed Axle Gears by Avoiding the Interference PhenomenonRelly Victoria Virgil PetrescuIt can be seen that the minimum number of teeth required to avoid interference for the standard pressure angle, normally on the alpha0 = 20° decomposition circle, is 13, corresponding to a transmission ratio i = 1 and increases with the transmission ratio i reaching to the maximum value of 18 teeth for i>100. For normal transmission ratios, values ranging … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 21 May 2019 · 6,488 accessesView PDF Cite

Review ArticleOpen accessFace Recognition as a Biometric ApplicationRelly Victoria Virgil PetrescuA facial recognition system is a technology capable of identifying or verifying a person from a digital image or a video frame from a video source. There are multiple methods in which facial recognition systems work, but in general, they work by comparing selected facial features from the given image with faces within a database. It is also described as … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 14 May 2019 · 18,781 accessesView PDF Cite

Review ArticleOpen accessSomething 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 PDF Cite

Research ArticleOpen accessDynamic Models for Rigid Memory MechanismsRelly Victoria Virgil PetrescuThe paper presents a dynamic model that works with variable internal damping, applicable directly to rigid memory mechanisms. If the problem of elasticity is generally solved, the problem of system damping is not clear and well-established. It is usually considered a constant "c" value for the internal damping of the system and sometimes the same value c and for the … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 6 May 2019 · 5,981 accessesView PDF Cite

Review ArticleOpen accessAbout Robotics, Mechatronics and Automation that Help us Conquer the Cosmic SpaceRelly Victoria Virgil PetrescuHere we have to mention that all these SF writings and many others that have existed over time, especially in the 20th century, have influenced alongside obvious screenings, young people and not just them, to think more about our role, robots, into a better world. The robot's key role is to help the man make his work easier, safer, more … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 6 May 2019 · 6,745 accessesView PDF Cite
