Abstract:The thesis which is described by this report is aimed at the design of an integrated cameramodule. The purpose of the module is to identify, lokalize, globalize and to communicate entities in surroudings of industrial robots. The creation of a prototype cameramodule, contains a combination of software and hardware. Based on prescribed requirements by the client, there has been made an analysis of platforms. These are dependent of the way of tracking entities. By designing the module to be open source, the costprice is lower than the 150 euros limit. The selected platform is Linux Ubuntu. The chosen software sets requirements to the hardware specifications. Ubuntu’s systemrequirements are translated to selected parts for the module. The result is that the module contains roughly three main parts: webcam, motherboard and the adapter. Visual markers are designed to identify and to lokalize entities. The markers are comparable with QR-codes, but only consists out of a 3 by 3 matrix with a defined construction. This gives the need to base the design of the software on augmented reality.Hence, a webcam system together with specific software is created to locate the markers. The sofware program is based on Aruco and OpenCV and converts the image of markers from the webcam to strings, communicable over WiFi. The casing of the module is designed based on the mapping of the parts. After several form studies a casing was designed. It consists out of a frame, together with plastic shells. The design converts the computer look into an integrated module. The designed case is modelled in SolidWorks. The technical model is the base of the realized prototype. The analyze the quality of the module, use tests are preformed. This ensures that the precision and accuracy can be determined. The results of these tests satisfy the requirements, so that the module works in the set environment. Also there has been taken into account of vibrations, movements and saturations of markers.Combining the software, hardware and casing, a fully developed prototype cameramodule is designed and with that the end product of this thesis. The module is easily copied and is without systemchanges capable of working with multiple at once. The casing can be produced of conventional production methods. This way the design meets the set requirements and achieves the objectives of this thesis.
