The article is focused on testing selected communication protocols for the Internet of Things. The aim of the experiments was to find a suitable communication protocol to build a smart device of home automation. The recent developments in the field of communication protocols and data processing are providing a new form of constrained communication, while describing how the Things talk to each other in the Internet of Things. With growing number of connected devices in industry and commercial field, there is a need for the devices which can handle the new forms of communication, handle sensors and operate the battery power. The gathered data is either processed on the “edge” of the network or on the cloud platforms. Authors present a comparison of selected newest communication protocols, while reflecting on the results of their experimental testing.

Paper is focused to the development in designing of technical systems and present methodology approaches. For a long time, engineering design research has been focused on the development of various design theories, methodologies, methods, tools, and procedures. Engineers to more efficiently design artefacts have subsequently used that design methods. However, as the artefacts have grown in complexity, the need for new methods has become obvious. Also, in a nowadays world, increased competition and globalisation require organizations to re-examine traditional product development strategies. While the difficulties in design synthesis are caused by a wide variety of issues, the complicatedness under problem size is so essential that it make procedural design knowledge insufficient to generate superior design solutions.

Pneumatic muscle actuators (PMAs) differ from general pneumatic systems as they have no inner moved parts and there is no sliding on the surfaces. During action they reach high velocities, while the power/weight and power/volume rations reach high levels. The main drawbacks of PMAs are limited contraction (relative displacement), nonlinear and time variable behaviour, existence of hysteresis and step-jump pressure (to start radial diaphragm deformation) and also antagonistic connection of PMAs to generate two-direction motion. These make PMAs difficult to modelling and control. In this paper a new stiffness model and the variable-stiffness spring-like characteristics are described and tested using two Fluidic Muscles made by Festo Company. The muscles have the same diameter, but different length.

Urgency of the research. It is important to point out at innovative elements in the field of robotic arm programming. At the same time, we want to provide guidance, how to work with these elements further and implement these principles into the automated workplaces control. Target setting. Purpose of article is to give some form of instruction, how to work with innovative elements for robotic arm programming. Actual scientific researches and issues analysis. Currently, there are already many innovative and user-friendly programming units on the (automation) market today. Therefore, it is necessary to make the professional public aware of the new possibilities of programming robotic arms. Uninvestigated parts of general matters defining. The manufacturer's user manual is the most frequently used in this area, but it does not sufficiently describe some aspects of robotic arm programming. Therefore, we consider it is necessary to address at this issue. The research objective. The aim of article is to provide some kind of instruction, how to work with special equipment, like is programming unit (called also pendant). The statement of basic materials. For realization of advanced programming functions is good to have a suitable material how to solve path sequence and automation process at the workplace. Conclusions. Published article presents selected programming aspects for robotic arm with emphasis to specialities of robotic arm manufacturers. Presented article provides a closer view to some detailed solution regarding robotic arm programming that are not often and sufficient described at providers manual.
