Master Thesis Lower Body Dynamics for Rotational and Translational Activities: Cycling and Stair Climbing(01. Izmir Institute of Technology, 2023) Mihçin, Şenay; Mihçin, Şenay; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyEvaluation of human movement performance in activities of daily living is an important component in clinical and rehabilitation settings. Motion capture technology is an effective method for objective evaluation of human motion. Here, movement kinematics and kinetic data are obtained from healthy individuals. In this thesis, it is detailed the daily life movements based on stair climbing and cycling. The aim of this study is to examine the effects of human movement on the kinetic and kinematic variables of the hip joint during stair climbing and descending. Data were collected using the Qualisys motion capture system, force plates, ladder and bicycle. By analyzing data from different individuals here, great potential information can be gained for predicting the recovery and progression of movement for patients. In the future, the development of personalized therapy protocols in rehabilitation with individualized progression can be offered. Optimum design parameters for the individual device and exercise device can be obtained, and if the relevant joints are supported with implants, it is possible to obtain the necessary boundary conditions for personalized implant design and to collect the necessary data for implant design. The Results and Discussion Chapter illustrates and tabulates the calculated results. In the Findings and Discussion section of the thesis, the calculated results of the study are included. This section provides a comprehensive analysis of the data collected, highlighting the observed patterns, trends, and variations in hip joint kinematics and kinetics during selected activities. The Discussion section delves into the significance of the findings by comparing the findings with the available literature, identifying similarities and differences, and offering possible explanations for observed variations.Master Thesis Design, Development, Modeling and Control of a Stewart Platform(Izmir Institute of Technology, 2020) Tatlıcıoğlu, Enver; Tatlıcıoğlu, Enver; 03.05. Department of Electrical and Electronics Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyNeed for a six degrees of freedom test platform to be used in the inertial stabilization development tests of turrets, remote controlled weapon systems or sight systems is present in modern military technology development. To address this research issue, within this thesis study, a Stewart platform is built and is used for stabilization development tests of a sight system. To give a clear picture of the whole system, mechanical design criterion, electrical architecture, communication between system units and chosen hardware of the designed Stewart platform are presented in detail. After the design and development phases are completed, kinematic model is obtained via utilizing the computer–aided design model of the Stewart platform. The inverse kinematic expressions of the platform are made use of to calculate the required actuator behaviors for the platform to achieve the desired motion. Then, a cascade control structure is designed for control of both speed and position of the actuators where proportional integral controller is preferred. The designed control strategy is implemented to the Stewart platform where satisfactory performance is observed for it to be used in military vehicles.
