Development of a universal cell for optical part inspection in a robotic workplace
Cahlík, Radim ; Rajchl, Matej (referee) ; Adámek, Roman (advisor)
Cílem této diplomové práce je vývoj univerzální buňky pro optickou kontrolu včetně softwaru pro detekci vad, který používá metody umělé inteligence. Dalším cílem je integrovat buňku do robotického pracoviště a otestovat ji na rozdílných dílech s různými vadami. První část práce popisuje vývoj konceptu optické buňky a její návrh. Poté pojednává o systému pro optickou kontrolu, počínaje popisem objektivu a kamery a konče analýzou kontrolního softwaru, který pro detekci vad využívá konvoluční neuronovou síť. Další část se zabývá vývojem robotického pracoviště včetně návrhu dvojosého robota a komunikace mezi zařízeními. Nakonec je rozebráno testování na dvou rozdílných dílech s cílem ověřit funkčnost.

Using the image sensor for the identification of defects
Rybár, Vladimír ; Horák, Karel (referee) ; Bejček, Ludvík (advisor)
The thesis focuses on the use of cameras for detection of faults. The first part explains the basic concepts concerning the function of cameras and basic instruments of optical inspection. In the following part, various methods for programming the same inspection are shown. Data export for robotic arm is also programmed in desired shape. The programs are verified in a GUI from manufacturers Banner Engineering and Cognex. The proposed program is also verified using camera by manufacturer Banner Engineering. Thesis is concluded by processing and evaluation of different methods of programming, highlighting the advantages/disadvantages of using certain tools.

Noncontact monitoring of dimensional accuracy of large-scale 3D printing
Paulíček, Jiří ; Mendřický, Radomír (referee) ; Koutecký, Tomáš (advisor)
This diploma thesis deals with a design and manufacture of a scanner that is used for online monitoring of a large-scale 3D printing of concrete mixtures. The aim is to design a scanner usable with an active print head designed at VUT. The scanner works on the principle of active laser triangulation, where a laser line is projected on an extruded material immediately behind the nozzle. The projection of the laser line on the extruded materiál is captured by a camera. During the design, FEM analysis was used due to the sizing of the main parts of the scanner depending on the deformations caused by the operating load. Excessive deformations would cause measurement inaccuracies. The height and width are calculated from the image in the MATLAB software. This manufactured scanner was tested during the printing of a real object.
