Universal BLDC motor controller
Pijáček, Ondřej ; Pohl, Lukáš (referee) ; Veselý, Libor (advisor)
This thesis describes the design of universal control unit for BLDC motor powered from airplane power distribution system of 28 V capable of driving motor up to 10 A. The maximal engine power is about 250 W. Important prerequisite is possibility of driving various motor size without needs of changing wiring board using only the configuration in the auxiliary memory unit. To control different motors is enough one unit with one program without any way to interfere to the unit itself.

Roboarm Controlled by FITkit
Říha, Lukáš ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
The terms robotics and roboarms have a huge meaning in the today's world. This thesis describes the simple roboarm ROB1-3 control by the help of FITkit. FITkit has two main parts which are used for control - the microcontroller and the FPGA chip. The controlling of the roboarm is possible by the keyboard of FITkit or by the terminal. The motion is enabled by three servos Hitec HS-311. The servos are controlled by PWM signal which is generated by microcontroller of the FITkit.

Hexagonal Platform with Servo Control
Korgo, Tomáš ; Maršík, Lukáš (referee) ; Zemčík, Pavel (advisor)
Goal of the thesis is to show the possibilities of using ordinary hobbyist RC servos and means of their control by a computer. For demonstration of the capabilities of servos, we have created Stewart platform which is using hobbyist servos to position the platform. In the thesis there is explained principle of the inner working of a servo, their properties, abilities and also means of their control by a computer. In practical chapters of the thesis there is documented process of designing and implementing of functional Stewart platform along with specific properties of this platform which influence its design. This platform is also reviewed and based on the results we will show technical properties of the platform, advantages and disadvantages of using ordinary hobbyist servos to control the platform. Design of the platform and its documentation is created with respect to intent to make the ddesign, source codes, documentation available to public on wepages focused on aggregating of instructables and tutorials to make usage of outputs possible in practice.

Robotic Manipulator Controlling Using Microcontroller
Zemánek, Martin ; Škarvada, Jaroslav (referee) ; Růžička, Richard (advisor)
This master's thesis deals with control robotic manipulator ROB 1-3 using common joystick and microcontroller HC08 NITRON or HC08 LJ12. The goal of this work was creation of module for controlling axes position of servos included in robot by analog signal coming from connected joystick. There are formed possible suggestions about connecting individual parts together for both autonomous and version using development kit. Programming code suggestion is based on these connections during further development. The limitations of using it are described in analysis and final results are shown in statistics results.

Table tennis robot
Nguyen, Thuc Tuyen ; Věchet, Stanislav (referee) ; Marada, Tomáš (advisor)
This diploma thesis deals with designing and manipulating a robot for training table tennis. Robot's mechanical construction is based on aluminium profiles supported by various standardized assembly units, such as rotating bearings, plain bearings, threaded rods... The front-end part of the robot, which requires better deformation property and lighter weight, was made from ABS material using 3D rapid prototyping technology. The design of the robot allows its body to rotate around three axises. Thanks to the high dynamical ability, robot can be set to throw balls to various places on the playing table, with different types of ball spin. Balls will be shot out by two rubber wheels, which are attached to two electrical DC motors. By driving the speed of the two motors, we can control the speed of the ball, as well as speed of its spin. All robot's activities are driven by an embedded system designed using microcontroller ATMega128. A firmware for controlling robot's function was writen and flashed into the microcontroller. End-users might communicate with the robot via a system of buttons and a text LCD display. The built robot was tested and it has shown its ability to throw balls to 6 different places of the playing table, at different speeds, with different types of ball spin, and different spin speed, according to the parameters set by user.

Position control of servo with discontinuouns rechangeable speed
Jindra, Pavel ; Věchet, Stanislav (referee) ; Němec, Zdeněk (advisor)
Diploma thesis work includes simulation of compensation of control for discrete. The aim of the work is a solution positioning control of servomotor drive piston, which is controlled by pass of the pressure oil with the help of several electromagnetically controlled switchboards with the orifice in the output channels. The verification activities of the regulated system is done using simulation in Matlab/Simulink and Matlab/Simulink, Matlab/Hydrosim. The requirement on the created model is to verify the behavior of the system to be modified to be used for the further development of the issue
