Collision Avoidance System for Mobile Robot
Dzuro, Daniel ; Hájek, Josef (referee) ; Herman, David (advisor)
This bachelor's thesis deals with the anti-collision system for mobile robot which is often liable to the collisions with other objects. Expensive parts of the robot could be saved thanks to the system. The main issue of the thesis was to design the system of premature reaction and it's application to the existing system which would help prevent the collision on time. Not only the breaking system was used to stop or slow down the vehicle but also the cooperation with the prediction of the vehicle's direction control was needed. Laser rangefinder and ultrasonic sonar were mainly used for this purpose.

Robot Controlled by PIC Microprocessor Unit
Heřman, Petr ; Luža, Radim (referee) ; Rozman, Jaroslav (advisor)
This thesis describes design of a cheap robot. It includes implementation of firmware of low level control unit based on microcontroller PIC. The firmware drives motors, gains sensors data and communicates with the high level control unit. Furthermore the thesis presents realisation of connection to the robotic operation system ROS and its standard structures allowing usage of existing packages for the robot teleoperation and displaying sensor data on the remote computer. The thesis finally reports experiments with the robot. The constructed prototype is the model of the robotic lawn mower, however the whole solution has universal usage.

The construction of a mobile robot for monitoring ambient temperatures
Čejka, Štěpán ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This diploma thesis deals with the design and control of the mobile robot with caterpillar tracks on the basis of information obtained via infrared thermocouple. The work includes firmware implementation for robot chassis control and communication with the sensors used. The functionality of the proposed system is demonstrated on a robotic task when the robot is searching the source of excessive heat within his surroundings. The theoretical part deals with the basic description of the common robotic chassis, contactless temperature measurement, further analysis of the components used and their principles. The practical part is devoted to the firmware implementation and detailed description of selected problems. In the end of the thesis there is a summarization of the achievements and the success of the robot while detection of the suspicious objects with high surface temperature.

Control of inverted pendulum model
Zapletal, Vít ; Najman, Jan (referee) ; Spáčil, Tomáš (advisor)
This thesis is connected to bachelor thesis of Bradáč, M.: Design, production and testing of education model ''Inverted pendulum''. It deals with analysis of faults and construction imperfections and subsequently their solutions. It further describes development of controll algorithm in Matlab/Simulink. The end is dedicated to automatic code generation and inverted pendulum controll by microcontroller.

The device for temperature sensors calibration
Tomíček, Pavel ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
The goal of this thesis is to design a device that allows calibrating temperature sensors. The device is made of a thermal chamber with Peltier module. Part of this work discusses means of temperature measurement, control and regulation. This work describes design of circuit and PCB. The device can precisely control temperature and temperature profile. It can also automatically calibrate Pt100 and Pt1000 sensors. User can control the device either by interface on the device or from a computer. Temperature range inside the thermal chamber is from 7,5 °C to 115 °C with ±0,10 °C error.

Thermostat for system testing at low temperatures
Sedláček, Jiří ; Hrdý, Radim (referee) ; Hubálek, Jaromír (advisor)
This bachelor thesis deals with proposal and construction of device that should serve for testing of developed electronic circuits at lower temperatures than the ambient temperature in laboratory. Thermoelectric Peltier’s coolers are used for cooling. The temperature regulation is provided by microcontroller control. The thesis is divided into three parts. First part includes necessary theory for realization of the device. In second part there is the detailed description of construction and function of the device. The third part summarises the measured parameters of the device. The thesis includes the technical documentation.
