Innovation of suspension mechanism for mountain bike
Hrubý, Patrik ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
Bachelor´s thesis includes the description, the analyze of the issue and innovations of the bike suspension for mountain bike, including design of the geometry, shape and propose of the production in the individual production devices. Belonging work is also construction 3D model of the particular parts the bike suspension and making mechanical drawing. The next thesis hints as exploitation of the modern technologies as is reverse engineering, making models in program Autodesk Inventor or work on 5-axis CNC milling machine and their interaction.

Structured-light 3D scanner
Hadzima, Jaroslav ; Chromý, Adam (referee) ; Jelínek, Aleš (advisor)
3D scanner is a device capable of creating a model using analysis, most commonly from image data. 3D scanners could be divided into two major groups, contact and noncontact scanners. Aim of this study is to interpret problematics of 3D scanning with structured light. Specifically usage of Gray code patterns. There is step by step evaluation of individual hardware and software obstacles and possible errors, from calibration to final point cloud. In next section, there are included tests determining quality, precision and accuracy of scanning with given method. System is applicable to mobile robots and yet fully remotely controlled. The majority of enumerations is taking place in Raspberry Pi 3 model B, just visualization alone is done from computer.

Using "reverse engineering" approach when making replica of Al casting by lost wax technology
Bezděk, Adam ; Cileček, Jarmil (referee) ; Horáček, Milan (advisor)
The aim of this thesis was to produce a prototype casting of aluminum alloy with usage of reverse engineering technology. In a production process surface quality and dimensional accuracy was optimized. 3D scanning, FDM technology, ABSplus surface finishing possibilities and investment casting technology is introduced in theoretical part of this thesis. Practical part of the thesis includes description of original parts, their 3D scanning, usage of RE and RP, production of new castings and evaluation of their dimensional accuracy and surface roughness.
