Approximation of functions determining colony activity using neural networks
Nevláčil, Jakub ; Ligocki, Adam (referee) ; Honec, Peter (advisor)
Bees as a primary pollinator are an indispensable contribution to global agriculture and food production. However, their numbers have been constantly declining in recent times, primarily due to climate change, parasites or the effect of pesticide use. Understanding their behavior and reliably determine their activity and health could significantly prevent or slow down their decline. That is why this work deals with the development of a device for the acquisition of useful data from beehives, which could be used to determine the activity and health of the bees. Furthermore, this work deals with analysis of the accumulated data using machine learning methods with an emphasis on determining the activity and health of the bees.

Automated object tracking using robotic manipulator
Zelený, Miroslav ; Ligocki, Adam (referee) ; Chromý, Adam (advisor)
This diploma thesis deals with the tracking of objects using a robotic manipulator Epson C3 and a color camera. The work describes the basic qualities of the device to be used. The OpenCV library and its wrapper EmguCV are used as software tools for computer vision. It discusses the basic issues and principles of tracking objects in the image and introduces some methods of tracking. These methods have been tested and therefore their strengths and weaknesses, which appeared during testing, are listed here. Furthermore, there is a procedure for calculating the new coordinates of the camera and the manipulator effector using homogeneous transformations. The work contains the results of testing the algorithms and their evaluation. The output of the work is a test application for the Epson C3 robot.

GNSS for KAMBoat Floating Robot
Kuře, Václav ; Ligocki, Adam (referee) ; Kopečný, Lukáš (advisor)
The bachelor thesis "The Global Satellite Navigation Module for Floating Robot KAMBoat" is divided into two parts. In the first, theoretical part, the focus is on the theory that will be used for the practical part. The second part of the thesis is practical. Theoretical knowledge is applied here to design and navigation software. Part of the thesis is testing the navigation system under simulated conditions. Target of the thesis is to investigate the possibility of constructing a navigation module that would be able to generate navigation messages for the superior control system.

Methods for Simultaneous Self-localization and Mapping for Depht Cameras
Ligocki, Adam ; Jelínek, Aleš (referee) ; Žalud, Luděk (advisor)
Tato diplomová práce se zabývá tvorbou fúze pozičních dat z existující realtimové im- plementace vizuálního SLAMu a kolové odometrie. Výsledkem spojení dat je potlačení nežádoucích chyb u každé ze zmíněných metod měření, díky čemuž je možné vytvořit přesnější 3D model zkoumaného prostředí. Práce nejprve uvádí teorií potřebnou pro zvládnutí problematiky 3D SLAMu. Dále popisuje vlastnosti použitého open source SLAM projektu a jeho jednotlivé softwarové úpravy. Následně popisuje principy spo- jení pozičních informací získaných vizuálními a odometrickými snímači, dále uvádí popis diferenciálního podvozku, který byl použit pro tvorbu kolové odometrie. Na závěr práce shrnuje výsledky dosažené datovou fúzí a srovnává je s původní přesností vizuálního SLAMu.

Peristaltic Pump Controll Unit
Charvát, Jakub ; Kopečný, Lukáš (referee) ; Ligocki, Adam (advisor)
The work deals with the problematic of peristaltic pumps and it collects theoretical background information of this topic. The primary goal of the work is the implementation of peristaltic pump and the implementation of protection against equipment damage by overpressure. The overpressure evaluation system in this thesiss on the principle of current measurement of the motor pump. In this work, this premise is successfully tested and applied to the device. Another goal of this work is to create a desktop application that will monitor and control the pump. he data between the application and the device were successfully transfered by the MQTT communication protocol. The communication between the computer and the pump has been tested successfully.

Implementing the checkers game using a robotic manipulator
Lichosyt, David ; Ligocki, Adam (referee) ; Lázna, Tomáš (advisor)
The thesis starts with a field research about existing robotic systems with implemented checkers or similar desk games. In its next parts are described posibilities of controling robotic manipulator Fanuc LR Mate 200iD 4S using controller R-30iB Mate from platform ROS located on external hardware. In few next pages of the thesis there are mentioned designed and used physical models. Following chapters describe real time game situation detection, game logic implementation and human input with safety in mind. At the end of the thesis there are mentioned rule checking algorithms, system operation instructions and possible future upgrades of the system.

New uncommon actuators
Novotný, Jan ; Ligocki, Adam (referee) ; Kopečný, Lukáš (advisor)
This report contains a list of new chosen uncommon actuators that emerged in the last 10 years, mathematical model of 3D-Elastomer actuator, construction and testing of 3D-Elastomer actuator. The list is divided by the priciple and the type to 6 categories, which are pneumatic actuators, hydraulic actuators, soft actuators, piezoelectric actuators, micro/nano actuators and shape memory actuators. The construction of actuator is using 3D printing technology and silicone molding to build soft pneumatic actuator with three degrees of freedom of bending. Actuator is then tested for its elongation and bending parametres.

Quadrotor altitude stabilization
Ligocki, Adam ; Kříž, Vlastimil (referee) ; Gábrlík, Petr (advisor)
The aim of this thesis is to design and implement a vertical stabilization for drone developed at the Department of Control and Instrumentation of the Faculty of Electrical Engineering and Communication. Work gradually deals with summary of already existing solutions of already existing projects, analysis of individual sensors possible to be applied in this project and evaluate their pros and cons for measuring the flight altitude. It also deals with the mathematical apparatus suitable for processing altitude data and the design and implementation of the controller for the movement of the drone in the vertical axis. The conclusion summarizes the results achieved on real hardware.

Map machine recognition and optimal path planning
Peška, Jaroslav ; Ligocki, Adam (referee) ; Chromý, Adam (advisor)
This masters thesis continues in the work of two previous theses dealing with machine understanding of maps and modelling terrain. The final program also has to be able to interpret position data from dataloggers and integrate it with the loaded map. The goal for the program is to serve during training of Czech orienteering runners. Position measurement and storage is researched first. Also researched are map markers used to define the terrain. Afterwards, past approaches are evaluated, including identification of most severe issues hindering the usage in real world applications. Many improvements are proposed, for example methods to remove noise in the input data, or to improve processing speed. Lastly, a set of possible improvements to the original applications are made, i.e. methods for denoising the input data or for speedup of the image processing. Proposed improvements are then implemented, the most impactful being processing speed and contour segmentation improvements.
