    Design of a Rescue Robot for Search and Mapping Operation
    (Izmir Institute of Technology, 2006) Gümüş Akdemir, Derya; Keçeci, Emin Faruk
    The aim of this thesis is to design a mobile robot for rescue operations after an earthquake. The robot is designed to locate injured victims and life triangle in debris, to create a map of the disaster area and to collect the necessary information needed by digging and support robots in order to the database center. This robot enables us to rescue the victim in the shortest time with minimum injury. This will let us risking the lives of the rescue teams much less as well as rescuing much more victim alive.Robot is designed with the longitudinal body design. Shock absorber system gives the damper effect against falls as well as adding advanced equilibrium properties while passing through a rough land. Driving mechanism is a tracked steering system.Front and back arm system is developed to provide high mobility while overtaking the obstacles.Secondly hovercraft type robot, which works with the cushion pressure principle, is designed as a rescue robot. It is thought that if the adequate height is supplied, the robot could manage to overcome obstacles.As a third design, ball robot, which could easily move uphill and has a capability to overrun obstacles, is studied.Jumping mechanism will be working by magnetic piston.In addition robot is equipped with the sensors so that it has capable of the navigation. In order to achieve feasible sensor systems, all electronic components are evaluated and the most effective sensors are chosen.

    Wearable exoskeleton robot design
    (Izmir Institute of Technology, 2007) Gün, Volkan; Keçeci, Emin Faruk
    In this thesis study it is intended to design a wearable exoskeleton robot which will replace paralytic or disable people.s legs and provide to walk. The wearable exoskeleton robot will be an intelligent system that fulfill the gait necessities, climb the slopes up and down, and remove the disadvantages of the wheelchairs and mobility aid vehicles. Robot will be a wearable device like a trouser and it will work to carry out daily duties for users. Robot will increase user.s maneuver capabilities and support users. legs and aid walking action for users thanks to 3-one degree of freedom (DOF) joints which are designed for each leg and are powered by DC electric actuators. Design of the wearable exoskeleton robot includes, modeling and designing of the robot using a parametric solid modeling computer program (Solidworks), selection of the most suitable material for the design characters and robot manufacturing processes, strength analysis of the critical part of the robot, mathematical modeling of the system, design and manufacturing of the test machine and finding the most suitable walking combination by investigating degree of freedoms of each joints on the legs. In addition to mechanical design of the wearable exoskeleton robot, an electronic circuit is designed and manufactured in order to control each joint movement order and time in walking action. Moreover, in order to control the robot by the users, a keypad unit is manufactured on the robot and necessity functions are described in the program. As a result of this thesis; a wearable exoskeleton robot is manufactured to be used as a walking assistant.
