Modelling and Using of McKibben Pneumatic Muscle in Haptic
Kopečný, Lukáš ; Janotková, Eva (referee) ; Nevřiva,, Pavel (referee) ; Šolc, František (advisor)
This work describes exceptional properties of McKibben pneumatical muscle and introduces its state-of-the-art model. The mathematical model is extended especially in a field of a thermodymical behavior. A new model applies a method used for describing of a thermodynamical behavior of pneumatic cylinders until now. This method is significantly upgraded to fit a muscle behavior, particularly by considering a heat generated by a muscle internal natural friction. The model is than verified and discussed with a real system. The haptic part introduces a development and design of a haptic glove interface for the use in robotics, especially in telepresence, or in VR. The force and touch feedback is provided by Pneumatic Muscles controlled by an open loop algorithm using the introduced mathematical model. The design is light and compact.

Tactile Feedback Stimulation
Lang, Matěj ; Harabiš, Vratislav (referee) ; Kopečný, Lukáš (advisor)
This bachelor's thesis is focused on building and testing a tactile interface. As a first step, it describes various methods of creating a tactile stimulus and mentions basic physical principles used. The direct electrical stimulation was chosen as suitable candidate for replication. For this there was created high voltage DC voltage source controlled by Arduino Nano. Also a PCB accommodating series of electrodes connected to control the flow of current. The system is controlled by STM32F4-Discovery. In thesis is described design of PCBs and all created software. The board has been tested and improvements were proposed.
