Design of control unit for an autonomous vehicle
Vobruba, Martin ; Formánek, Martin (referee) ; Adámek, Roman (advisor)
The topic of this bachelor thesis is designing control unit for an autonomous vehicle. The new ECU replaces the old one which was without access to the source code, so its functionality couldn’t be modified. The purpose of the ECU is to receive a message from the control computer, process it, control the actuators according to the orders and inform the computer about their current state. The first part of the thesis is research of the vehicle kinematics and CAN bus. The practical part focuses on the analysis of the previous ECU which is crucial to its replacement. It is followed by the firmware and hardware design. The last practical part of the thesis is the testing of the new ECU’s functionality.

Control unit for CNC milling machine
Pecka, Josef ; Tomíček, Pavel (referee) ; Levek, Vladimír (advisor)
This thesis deals with the control of CNC milling machines and routers, their motion drives and spindles and the necessary hardware for the implementation of such control. It also includes universal control softwares that can be configured for use on a particular CNC. Based on this knowledge, the requirements for the control unit are then determined and suitable electrical components are selected and used in the design of this unit. It is then implemented and its key elements measured.

Increased suction speed of the fire pump using CAE
Hluší, Martin ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
This thesis adresses the issue of designing a new system for flooding the centrifugal pump equipped in the PS-12 type motorized fire pump. Initially the fire attack as a sport and the motorized fire pump PS-12 with the gas vakuum pump are described. Then the problem, this thesis adresses, is covered. The next chapters describe the Computer-aided engineering method and fluid flow with regards to flow through nozzles. Practical part of this thesis starts with simulations of the current gas vakuum pump equiped on the PS-12 pump. The design process of the new flooding system is described next and simulations as well as testing of the constructed prototype are used to validate its function.

Predicting spark-ignition engine emissions
Jirout, Petr ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
This diploma thesis deals with the possibility of predicting emissions of SI engines. The aim was to create an algorithm for predicting unburned hydrocarbons and carbon monoxide, based on ECU signals. The algorithm is based on practical experiments with SI engines. In the summary, the issues and the possible use of the created algorithm following the incorporation of EU7 are outlined.

The control unit of the door systems for public transport
Jablončík, Lukáš ; Vlachová Hutová, Eliška (referee) ; Friedl, Martin (advisor)
The topic of my bachelor´s thesis is to design a control unit of the door systems for public transport. The control unit is designed by using modern components. Their availability should be not less then ten years. The unit is controlled by a microcontroller ATMEGA and the motor is switched using the h-bridge. The control unit has ten programmable inputs and two switching outputs. PCB design is optimized for mass production. The result is a functional prototype of control unit.

Group of Walking Minirobots - Movement Synchronisation
Mihál, Jakub ; Florián, Tomáš (referee) ; Žalud, Luděk (advisor)
The aim of the work presented here is to get acquainted with the construction of the Robonova-I humanoid robot and with Ing. Florián’s dissertation “Control unit for humanoid robot”. Both the construction and the dissertation conclusions were tested, compared and, in the next part of the work, evaluated. Finally, a new software solution to the robot control and wireless communication was worked out.

Control units for small DC motors with universal software interface
Hlouš, Jaroslav ; Březina, Lukáš (referee) ; Houška, Pavel (advisor)
The purpose of this thesis is to design and implementation of the control unit for DC motors. Design is based on the concept of universal communication interface, which has been designed for simplification of communication between individual control systems. Control unit has been realized for DC motors within supply voltage range from 6 to 48 V, and maximal continuous current 2,5 A. For realization, we have used microcontroller LPC2103, and full bridge driver TLE 6209. In the thesis, we have described particular developmental steps of the control unit.

Electronical irrigation system
Endrych, Václav ; Šír, Michal (referee) ; Bradáč, Zdeněk (advisor)
This bachelor thesis is concerned with automatic irrigation systems. It describes their purpose their usual fabrication and their individual components, especially electronic controlling units. The goal of this thesis was to construct such unit. Thesis furthermore describes the process of design and realization of this device, starting from determination of the basic requirements on the device, through design of its circuitry and construction, up to design of included control program and final tuning of the device. Resulting controlling unit is functional. It can drive four branches of an irrigation system and measure relative humidity by four independent sensors. Unit offers a number of different functions and is controlled from remote user interface via an Ethernet connection.

System for Autonomous Navigation of Toy Car on a Race Track
Katrušák, Jaroslav ; Bidlo, Michal (referee) ; Šimek, Václav (advisor)
The goal of this project is the implementation of a system for autonomous control of a toy car model on a racetrack. First part of this project is a study of typical ways of laying out a racetrack for the movement of a model car and a follow-up study of possible ways of implementing the autonomous movement of the model on the racetrack. The next part is devoted to the hardware and software side of the implementation of the proposed system. The penultimate part presents the proposed system for obstacle detection, it's implementation and resulting properties. The last part of the project presents the final implementation of an autonomous model capable of independent driving on a set racetrack, reading signs and reaction to obstacle located on the track.
