Mechatronic Design of a Completely Mechanical Quick Changeable Joint for Multi-Purpose Explosive Ordnance Disposal Robots
(Izmir Institute of Technology, 2006) Kor, Mehmet Bahattin; Keçeci, Emin Faruk
The EOD robot is a mobile robot used in replace of a human in explosive ordnance disposal operations of searching, detecting and handling of explosive materials. Nowadays the EOD robot.s tool capabilities and overall performances are at lower levels because they are only able to use one kind of tool (gripper) for the whole bomb disposing process. The aim of this study is to design a completely mechanical quick changeable joint which will be used in the EOD robot to automatically change the tools. By changing the grippers automatically, the robot firstly does not require to be called back for tool change and secondly can achieve different operations on the explosive material. In the locking mechanism of quick changeable joint, hydraulic and pneumatic systems are not preferred because of their weight and volume on a mobile robot. Electromagnetic locking systems are also not considered because of possible electromagnetic interaction between the arm and explosive ordnance. The reason of designing a completely mechanical joint is to eliminate the use of another actuator for controlling the locking mechanism. An EOD robot with a quick changeable joint will be able to use different tools and accomplish complex tasks by using these different tools. Usage of this quick changeable joint in different robotic applications such as tool holding in CNC machines, lifting and pulling applications will also make an increment in the robot.s processing capacity and efficiency. This project consists of designing a completely mechanical quick changeable joint. In order to understand the best design, four different joints are designed, the critical parts are analyzed for strength and prototypes of the joints are manufactured. To test the life cycles of the joints a pneumatic test machine is designed and manufactured. After the tests, the joints are evaluated for design parameters are the best design for different purposes are determined.
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.
