In recent times, the ever-higher peripherical speeds in rotor-dynamics drew the attention of the turbomachinery community. Indeed, the machine rotational speed is crucial for the system efficiency. With this in mind, the design and the assembling of a complete rotor-dynamic test rig were completed at the Mechatronics and Dynamic Modelling Laboratory of the University of Florence. In this setting, the rotor is supported by two tilting pad journal bearings, and it achieves a shaft-bearing surface speed of 115 m/s at 40 000 RPM, thus reaching challenging operative conditions in terms of relative speed between shaft and bearings. Thanks to the proposed test rig, it is possible to study the entire physical phenomena of a rotor-dynamic system, from the dynamic, thermal, and fluid-dynamic points of view. Furthermore, the work validates experimentally the model analysis, in terms of Campbell's and Waterfall's diagrams, and rotor orbits. In such a way, working on a real-scale test rig, it is possible to compare models of different types of tilting pad journal bearings under different operating conditions, such as the rotor speed and the bearing lubricant temperature.

Robot teleoperation is an essential tool for performing complex tasks that require dexterity beyond the capabilities of state-of-the-art algorithms. Existing teleoperation methods are often non-intuitive for human operators or require special sensors and equipment, making them cost-ineffective and impractical in many scenarios. In this paper, we propose a robot arm teleoperation framework that relies on monocular camera images. The proposed framework first uses lightweight neural networks for estimating the human operator body pose and recognizing their hand gesture. An efficient inverse kinematics algorithm then finds the desired robot arm configuration, achieving end-effector motion that imitates operator's wrist movement. Our teleoperation framework can be executed on an average laptop using a web camera with any robotic arm that has a ROS interface. We verified its performance in real-world experiments with a Kinova Jaco robotic arm, demonstrating the ability to grasp and move an object in the environment.

This paper presents the design of a robotic medical device for upper limb rehabilitation based on a parallel mechanism driven by cables. The design of this device is able to adapt to the specific needs of the patient and, thanks to its portability and lightness, it is suitable for autonomous use at home. Particular attention was paid to the study of the kinematics of the device and the design of the main mechanical components. The kinematic model of this design has been subjected to several simulations.

This paper focuses on the design of a spiral groove thrust bearing for a high-speed, small-scale radial compressor rotating at 200 krpm. The analytical model from Muijderman is taken into account to estimate the load carrying capacity and the stiffness of the thrust bearing. In this preliminary study, the static analysis is carried out in order to design the geometry of the bearing, which is of spiral groove type. The outer and inner diameter of the thrust bearings are 30 mm and 17 mm respectively. After a short recall of the literature model, the geometry of the bearing is optimized in order to maximize its load capacity. Future investigations will be aimed at evaluating the bearing stability in dynamic conditions. The experimental validation of the model is also forecast.

Virtual reality (VR) can serve as a revolutionary technology in surgery, where robotic systems are used to assist residents in training and accumulating knowledge without risk. In this article, a simulator was developed using virtual reality technology designed for a surgical robotic system used in the single-incision laparoscopic surgery (SILS) procedure. For this system, artificial intelligence is employed for the automatic positioning of the mobile platform of the parallel robot above the SILS port. On the mobile platform, there are two active instruments and a laparoscopic camera, which can be easily inserted through the SILS port by means of two controllers and voice commands.

Popular and widely referred text on graphical synthesis of crank-rockers invariably mentions Hrones and Nelson Atlas of the coupler curves. The studied coupler points, situated in a limited coupler space, and at the nodal points of the superimposed grid trace coupler curves with "granularity". The performance of coupler points lying between the two adjacent coupler points is left to the user's imagination and intuition. This method of providing gross information is suitable only for the initial selection. It can be modified further to meet the targeted output. Otherwise, it remains a solution with compromise. This paper demonstrates a graphic-numeric methodology for modifying/refining the initial selection by effective iterations. Using instantaneous Inflection Circle properties, three different approaches for iteration are demonstrated. Inflection Circle is a locus of infinite possible coupler points tracing some approximate straight path. In this study initial graphical analysis is completed using GIM software. Neural Networks are trained to reduce the time required for completing remaining iterative synthesis. One crank rocker is randomly selected from the Atlas and three routes for modifications using the mechanism specific trained Neural Network are demonstrated for modifications in the length of straight paths.

In this study, we develop a new surface treatment technology for diamond-like carbon (DLC) coatings using dielectric barrier discharge (DBD) in ambient air. After DBD irradiation, the friction coefficient was reduced from 0.26 to about 0.01. Itwas also found that the surface exhibited super hydrophilicity and high surface energy after DBD irradiation. In particular, nitrogen-containing DLC produces an acidic liquid film on its surface after DBD irradiation. Surface analysis indicated that the introduction of oxygen-containing groups on the surface after DBD irradiation might be the reason for the superhydrophilicity. The reason for the low friction was the interaction between the graphitized material and the highly acidic liquid.

A full-scale prototype of a 3-DOF 4R-5R parallel mechanism for an wearable end-effector type upper limb assistive robot called as "WELiBot" is fabricated. Owing to its kinematic structure, it can assist user's upper limb in motions where generation of vertical force and constraint along/on certain geometries are required. EMG measurements were collected from a healthy person as a preliminary evaluation prior to clinical trials with hemiplegic patients. Muscle activities of the person's upper limb were measured for the cases with and without assistance, and the results were compared. The results show that when the robot assisted the arm raising motion, activity in specific muscles of the upper arm and forearm decreased significantly. This confirmed the effectiveness of the motion assistance by the robot. On the other hand, no decrease in activity was observed in the shoulder muscles.

This paper proposes a novel test rig for the dynamic identification of elastomeric O-Rings. The identifications are performed by means of the Base Excitation - Resonance Mass (BERM) method. Thanks to its simple and compact structure, the proposed test bench makes it possible to assess the O-Ring performance under different working conditions: squeeze, stretch and temperature. Finally, the effectiveness of the test bench and the adopted identification procedure is confirmed by the results of some preliminary tests.

The use of complex mechanical systems in different tasks assumes the controlling of each motor from the kinematic joints known as dynamic control equations. The moving differential equations for any mechanical system can be expressed very efficiently based on principles from Analytical Mechanics, among which the method developed by Lagrange-Euler provides explicit equations of motion. The Lagrange-Euler second kind formalism is an analytical approach extremely useful in modelling of multibody systems which uses an important notion in dynamics-kinetic energy. These equations can be used to analyze and devise advanced control strategies by mathematical modeling based on mathematical algorithms. In this paper, for two robot structures (serial and mobile), considering that are working independently, will be established the dynamic control functions, using a generalized algorithm, consisting in geometrical, kinematical and dynamical modeling.
