In the present day, automobile manufacturers demand a certain torque range from hinges provided by supply industry. However, there are no torque measurement system used by the industry to measure this kind of mechanisms and the available systems cannot meet expectations. The purpose of this study is to design a computer-based torque measurement system and to produce its prototype. This system will be used to measure torque range of the vehicle front hood hinges and to control whether torque value is suitable or not. The developed system is an integrated mechatronic system that contains such subsystems as mechanical, electronic and control system. It is expected that the developed torque measurement system will fill an important gap in the relevant industrial sectors and will find widespread application area.

One of the main problems in path planning for multiple mobile robots is to find the optimal path between two points so that robots can follow the shortest path and consume the least energy. Also, motion planning is important to avoid collisions if multiple mobile robots are running together within environments with obstacles. In this study, motion planning for multiple robots has been proposed. It is desired that robots could move in coordination with each other from the starting point to the destination point on a plane. The coordinates of the objects and mobile robots have been acquired using image processing with a single ceiling camera. The path planning for the shortest distance has been performed using A* algorithm in dynamic frame between robot-object and object-target point, respectively. A graphical user interface has been developed based on MATLAB GUI. It is hoped that the developed system will have a wide area of applications in industry and will make important contributions for the improvement of manufacturing, assembly, transportation and storage technologies.

Pumping stations are some of the most important facilities of water administration. Continuous operation of these facilities is of utter importance, to be able to serve at all times. Maintenance of these facilities is also crucial for uninterrupted operation. In this study, the functioning of the predictive maintenance technique, which is based on the vibration analysis, is briefly addressed, and the application of the technique in a real system is presented. In the real system, the steps that must be done in order to apply this system are shown step-by-step. At the end of the study, the failures determined by using the predictive maintenance method are analyzed, and solution suggestions are presented.

In this study, a new communication protocol, which addresses the rotary table, has been designed. Developed system works over a single line and is using slip rings. The designed communication protocol ensures the half duplex communication for multiple stations over a single cable. During the protocol design, media access methods, coding techniques and multi-node synchronization techniques were examined. These techniques have been adapted, updated and combined for the study, during the formation of the communication protocol. The designed protocol was tested and verified in the simulation environment with original software, on the microcontrollers. The protocol is aimed to be open source, flexible, easily applicable and a new solution for the distributed control problems in the field of automation and for the rotary table systems in particular.

This study aims to develop an integrated control system to prevent the indoor loss of water. In general, these losses occur while using the hot water, because of forgetting to close the water batteries during the water cuts, or due to faults in washing machines, dishwashers and indoor plumbing systems. In this study, a specialized solution is developed for each type of losses. Then, the developed three subsystems were combined and transformed into an integrated system. This study shows that water losses in the housing can be prevented by using advanced technologies. There are similar systems in practice, but this study is different from the others with regard to its holistic approach, addressing all three problems together. The contribution of the system to economic and social life will be great, when water saving and environmental damage are considered.
