Exoskeleton robot is a supporting structure for soldiers to lighten the weight of their equipment and for people who suffer from medical problems such as lifting, walking etc. This study, the aim is to design an exoskeleton robot for arm that consists of finite self-reconfigurable modular robots, where each modular robot have connections to neighbor modular robots. Firstly, finite element method is used to calculate the stress at each connection. This is followed by the system making a decision by itself on which modular robots will break and where these modular robots will re-connect in the structure, decreasing the stress by utilizing graph theory method. In this thesis, the modeling exoskeleton and the stress analyses have been execute by using Ansy software. Then the obtained results are transferred to Matlab, and it is determined which node will separate itself. Also, in this thesis, a real exoskeleton robot for assisting the load lifting is designed. This exoskeleton robot can lift a certain level of weight. If the system is overloaded, the least important module within the exoskeleton robot is slid to the point where the load is at highest level.

Single and multi-frame motion deblurring for legged robots: characterization using a novel fd-aroc performance metric and a comprehensive motion-blur dataset Gültekin, Gökhan Koray; Saranlı, Afşar; Department of Electrical and Electronics Engineering (2016) Dexterous legged robots are agile platforms that can move on variable terrain at high speeds. The locomotion of these legged platforms causes oscillations of the robot body which become more severe depending on the surface and locomotion speed. Camera sensors mounted on such platforms experience the same disturbances, hence resulting in motion blur. This is a corruption of the image and results in loss of information which in turn causes degradation or loss of important image features. Most of the studies i...
Synchronization of multiple serially actuated robotic legs using virtual damping control Özen, Merve; Saranlı, Uluç; Department of Computer Engineering (2018) Even though one-legged models have been found to be a useful fundamental basis for understanding and controlling the dynamics of running, animals and physical robots alike often use multiple legs for additional support, dexterity, and stability. In general, the dynamics of such multi-legged morphologies are more complex and their control is more difficult. A common problem in this context is to achieve a particular phase relationship between periodic oscillations of different legs, resulting in different lo...
Modeling and control of the three degrees-of-freedom parallel manipulated robotic sensor head Öğücü, Muhammed Orkun; Saranlı, Afşar; Department of Electrical and Electronics Engineering (2014) Legged robot platforms have distinct advantages over wheels in rough terrain and provide better mobility. Also in many applications, including military reconnaissance, disaster relief, hazardous site inspection, search and rescue applications benefit from the legged robots which is capable of moving safely at high speeds through rough natural terrain. However, with the increasing speed, fundamental difficulties like dynamic and mechanical limitations as well as control and computational limitations arise. A...
Optimal control of a half circular compliant legged monopod Özkan Aydın, Yasemin; Leblebicioğlu, Mehmet Kemal; Saranlı, Afşar; Department of Electrical and Electronics Engineering (2013) Legged robots have complex architecture because of their nonlinear dynamics and unpredictable ground contact characteristics. They can be also dynamically stable and exhibit dynamically dexterous behaviors like running, jumping, flipping which require complex plant models that may sometimes be difficult to build. In this thesis, we focused on half circular compliant legged monopod that can be considered as a reduced-order dynamical model for the hexapod robot, called RHex. The main objective of this thesis ...
