The Stewart platform allows simulation in six degrees of freedom. It consists of two irregular hexagons connected by six actuators – hydraulic cylinders. The controlled simultaneous retraction or extraction of the piston rods from the tubes of the hydraulic cylinders changes the length of each leg, achieving the movement of the upper moving platform, which is described using a mathematical background.

Efficient filtering is often crucial in the field of machines and devices, as the safe, reliable, and long-term as well economical operation of the entire system depends on the efficiency of the filter. This is especially true for heavily loaded hydraulic devices. In these devices, the efficiency of the filter and the ability to filter depend on various factors.

To control a hydraulic humanoid robot, it is necessary to design and optimize a hydraulic proportional valve with the lowest possible mass and size. The valve for the robot’s rapid movements must not only be compact, but also allow high flow rates while minimizing internal leakage.

In the introduction of the paper, the requirements encountered in modern machines and hydraulic equipment will be stated. The mutual impact between machine requirements, lubricant quality and specifications will be shown.

This paper studies the closed-loop control of an electrohydraulic velocity servo system with the use of the Lyapunov theory of nonlinear systems using integrator backstepping.

Digital transformation brings great technological and business challenges to organizations. It helps to change the patterns of business operations and has the effect of increasing innovation and competitiveness. At the same time, this is a great opportunity to develop and introduce many positive changes to the existing business and process model.

Due to their simplicity and versatility, load-bearing lattice structures allow construction in hard-to-reach areas, as they are easy to transport, easy to install and do not take up much space. Established engineering practice uses a modular structure design where the load-bearing structure is divided into height segments. In the presented study, we question the appropriateness of such an approach.

Contactless and automated optical inspection tools make headway in comparison to tactile methods in modern factories. In order to develop an advanced optical tool for inspection of metal components produced for the automotive industry, one faces a number of challenges.

Nowadays, vibrations are listed as among the most difficult challenges in the research and development of washing machines. This paper shows the method and procedure of setting up parameters for improvements of the performance of the washing machine by implementing the accelerometer.

The highly nonlinear nature of the electrohydraulic servo system is well known. The main reasons for nonlinear and non-differentiable mathematical descriptions of systems dynamics are fluid compressibility, leakage flows, friction forces, and nonlinear fluid flow through servo valve orifices.
