“…In the first stage the infrared camera and one of the modes of operation of the program Control_MRClutch were used. In this mode, the power supply of the coil was turned off when the previously set value of temperature has been reached [10]. Developing an automated mode, which turned off the power supply of the coil clutch, was crucial due to the long waiting time necessary for reaching a certain temperature value.…”

“…The latest research carried out by the authors allowed them to develop a prototype of MR fluid clutch [4]. The number of studies completed, enabled them to draw the conclusion that the fluid changes its physical parameters under the influence of heat, what consequently leads to the alterations in the mechanical parameters of the clutch [9], [10]. It was decided that this research would focus on recording the clutching torque during the operation of the clutch while applying two alternative approaches.…”

“…The test stand was developed basing on three types of software, due to their functions ( Computer program Control_MRCluch was written in C# by the authors. It is an extended version of the program CP&CiCL [10], with additional algorithm that reads the data from the memory of the digital signal processor and the additionally implemented correction mode of power supply parameters on the basis of the measured torque coupling.

The paper presents a research test stand developed in order to control the MR fluid clutch in a closed loop feedback. The individual elements of the stand with a focus on part containing the DSP processor that is used to record the signal voltage of the torque meter coupling are discussed. The influence of the temperature increase on the transmitted torque's value decrease is described. The waveforms of clutching torque without correction of power supply parameters (controlled in open-loop) as well as with the correction of power supply parameters i.e. the control in closed-loop feedback from DSP processor, are presented. Streszczenie. W artykule przedstawiono stanowisko badawcze do sterowania sprzęgłem magnetoreologicznym w zamkniętej pętli sprzężenia zwrotnego. Opisano poszczególne elementy stanowiska, z naciskiem na część zawierającą procesor sygnałowy DSP, który jest wykorzystywany do rejestracji sygnału napięciowego z czujnika momentu sprzęgającego. Scharakteryzowano wpływ wzrostu temperatury na spadek wartość przenoszonego momentu. Przedstawiono przebiegi momentu sprzęgającego bez korekcji parametrów zasilania (sterowanie w otwartej pętli) oraz z korekcją parametrów zasilania, czyli sterowanie w zamkniętej pętli sprzężenia zwrotnego od procesora sygnałowego DSP. (Procesor DSP, jako część zamkniętej pętli sprzężenia zwrotnego w układzie sterowania sprzęgłem z cieczą magnetoreologiczną, utrzymujący stały moment sprzęgający).

“…• the master subsystem implements wireless Wi-Fi communication with dedicated software on a PC and exchanges data with the slave subsystem using UART communication. The central unit of the master subsystem is the Raspberry Pi 3B+ microcomputer, which is additionally connected to an infrared camera Optris PI160 with using a Universal Series Bus (USB) [28]. • the slave subsystem directly controls a set of external components, reads data from the sensors mounted on the robot platform and controls motors groups.…”

There are many reasons why engineering structures are at risk of losing their loading capacity during their long-term exploitation, which may lead to hazardous states. In such cases, structures must be strengthened. The most popular technique of strengthening is based on the use of composite materials—fiber-reinforced polymer (FRP) elements attached to the structure with the special resins. FRP elements are applied externally, often in hard to reach places, which makes it difficult to diagnose the durability and quality of such a connection. In this study, a combination of a modern thermographic method was proposed, which makes it possible to assess the degree of damage to the contact of the structure with the composite material along with the running platform (wheeled robot) equipped with a set of diagnostic sensors. The development potential of such a solution for subsequent projects was also indicated.
