Design of post climbing machine
Obšil, Tomáš ; Mašek, Petr (referee) ; Krejsa, Jiří (advisor)
This bachelor thesis deals with post climbing machines. The theoretical part of the thesis deals with the basic division of robots and a description of different types of post climbing machines. The practical part of the thesis deals with the conceptual design of the post climbing machine. The machine is designed to carry on external payload in kilograms. The power supply of the post climbing machine will be realized by external power supply. Conceptual design is developed in SolidWorks.

Walking aids - review
Gazda, Ondřej ; Mašek, Petr (referee) ; Krejsa, Jiří (advisor)
This thesis is focused on walking aids. Exoskeletons an active (robotic) orthosis have achieved great development since its inception and have a large range of application. In this thesis I will focus on active orthosis that are intended for the disabled and the elderly. Described are the concepts of walking aids and recently implemented projects. Part of this thesis is an evaluation criteria proposal and evaluating of each concept according to these criteria. In the end the main developmental progress and problems yet to be overcome are summarized.

Digital secondary clock
Hortvík, Martin ; Mašek, Petr (referee) ; Marada, Tomáš (advisor)
The aim of this thesis is to design and implement control electronics for digital secondary clocks. The first part is focused on familiarization with the issue of the use of secondary clocks. Subsequently, the work deals with the design of electronics for generating minute pulses. The first part of the proposal is to ensure the correct voltage size and polarity of pulse. The exact timing pulses are provided by a pair of control circuits, Atmega8 microcontroller and RTC. The last part describes the procedure of realization of electronics by making schema, design and manufacture PCB, circuit revive and the implementation of the module into case.

The peripheral testing module design for mobile robot.
Mašek, Petr ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
This diploma thesis deals with design and realization of testing modules for detecting a defective peripheral in a mobile robot. One of the modules is intended for the diagnosis of ultra sonic range finder. The second one simulates the behaviour of these ultra sonic range finders, making it able to determine interface on which it is necessary to look for an error.

Design and realization of emebedded control system for mobile robot Bender II
Meindl, Jan ; Mašek, Petr (referee) ; Věchet, Stanislav (advisor)
This thesis describes design of the embedded control system for a four-wheel mobile robot Bender II. The first part deals with analysis of applicable platforms for embedded control system and four-wheel chassis kinematics. The second part focuses on describing the microcontroller Mbed, practical construction of the power supply for control systems and describes the framework created for communication with superior computer. The last chapter deals with one particular solution of speed measurement and transformation of this data into coordinates requested by supervisory system, which is a robotic framework ROS.
