Wideband 6GHz RF Signal Generator
Mička, Josef ; Kubíček, Michal (referee) ; Urbanec, Tomáš (advisor)
The goal of this thesis is a design of a wideband high frequency generator with an adjustable output amplitude. The generator is based on a frequency synthesizer ADF4355. The power level of an output signal is adjustable by an attenuator HMC1119. The created generator is accesisible trough an user-friendly control panel or by SCPI commands. Frequency synthesis can run in an integer mode or a fractional mode. The output signal has a very low phase noise when it is running in the integer mode.

Minisumo competition robot
Strašil, Vojtěch ; Bradáč, Zdeněk (referee) ; Streit, Jakub (advisor)
The work is devoted to the design of a competitive sumo robot for the Minisumo category. The aim of the bachelor thesis is to create a robot that is able to push its opponent out of the competition ring. The work deals with the design of the mechanical part of the robot, control electronics and software. The robot control is based on microcontroller ATMEL ATxmega32A4U. This, together with the DRV8874 H-bridges, provides control of a pair of DC motors. Feedback, for the correct orientation of the robot in space, is provided by four optical triangulation sensors and a single reflective optocoupler. Robot control software is written in C programming language.
