“…The application of Simpson's integration technique to analyse the data and obtain displacement/velocity graphs is presented in supplementary figure S1. The 3/8 rule is about twice as accurate as the standard quadratic method and it approximates the selected function more precisely [14]. This method offers negligible error, the integral value of f (x) is calculated in the node points.…”

A low-cost simple one-dimensional spring-mass system was constructed to investigate damped oscillations. The suspended mass in the system can move freely inside a cylinder containing a fluid. It provides an in-depth experience for demonstrating various concepts under oscillations. It can be used to probe the magnitude of damping forces in liquids such as water by analysing the oscillation of an immersed mass. Such low-cost apparatus can provide a powerful platform for instructions and a rich pedagogic experience. The manuscript presents an excellent idea that can be used as a simple laboratory exercise to explain damping in undergraduate courses on vibration.

“…However we want to increase the accuracy of localization, it is able to use feedback from MS® Kinect's three axis accelerometers. In case of information feedback from the localization process, it is possible to use the advantages of inertial navigation, because the information about the position could be obtained through the acceleration and gyro data from accelerometers and gyroscopes (Cviklovič et al, 2011). If the concrete application needs the precise mobile robot information about direction, an additional gyroscopic sensor can be used with the Cviklovič's (2013) method of calibration to achieve tolerance of ±0.5 degree.…”

This contribution is oriented to ways of computer vision algorithms for mobile robot localization in internal and external agricultural environment. The main aim of this work was to design, create, verify and evaluate speed and functionality of computer vision localization algorithm. An input colour camera data and depth data were captured by MS® Kinect sensor that was mounted on 6-wheel-drive mobile robot chassis. The design of the localization algorithm was focused to the most significant blobs and points (landmarks) on the colour picture. Actual coordinates of autonomous mobile robot were calculated out from measured distances (depth sensor) and calculated angles (RGB camera) with respect to landmark points. Time measurement script was used to compare the speed of landmark finding algorithm for localization in case of one and more landmarks on picture. The main source code was written in MS Visual studio C# programming language with Microsoft.Kinect.1.7.dll on Windows based PC. Algorithms described in this article were created for a future development of an autonomous agronomical mobile robot localization and control.

The modern technical development condition is closed due to tough business competitiveness, so the innovative information for teaching students on the best examples of engineering and designing is not available. This is one of the basic reasons that diminish engineering education effectiveness in the field of technical knowledge in modern agricultural production. The scientists of engineering departments work above the solution of this problem and adapt the results into practice-oriented teaching technologies. The example is the development of moisture meter for agricultural crops seeds on the world-famous microcontroller Arduino-based platform, oriented to master the foundations of real-time information technologies shown in this article. The principle of the moisture meter operation is based on the most common method for measuring humidity of seeds – dielectric technique. The classical algorithm of conversion, such as permittivity, capacitance, frequency, table-based transformations and temperature correction is given. In the research process the methods of software structural designing, including functionally-oriented techniques for realizing the functions of real-time information systems were used. The hardware and software for solving such tasks as measuring the humidity of crop seeds, as well as studying microcontroller devices operating on the base of classical measurement methods have been developed. It can be used to solve other engineering and scientific problems in the field of agriculture where capacitive sensors are used.
