With the advances in computer technology and the changing needs of people’s daily lives, robots start to offer alternative solutions. As one of these solutions, the branch of humanoid robots emerged as advanced robots that can interact with people. Robot faces are one of the most effective means of interacting with people; since they can express their emotions and reactions through facial mimics. However, the development of realistic robot faces necessitates the knowledge of the trajectories and displacements of actual face mimics. In this study, a setup (both hardware and software), that can be used for tracking critical points on human face while exhibiting mimics, is developed. From the outputs of this setup, the mimic trajectories are going to be extracted. The setup is designed and manufactured to be durable to external effects so that with a single camera calibration procedure the 3D reconstruction can be carried out several times. The setup consists of two webcams that are specially oriented for mimic tracking. The images taken from the cameras are corrected; their features are extracted using image processing algorithms; the centroids of the features are found; correspondence is carried out and the reconstruction is made. This system can also be used for any special point tracking or volumetric measurement purposes.

Design of a mobile robot to move on rough terrain Kırmızıgül, Uğur; İder, S. Kemal; Department of Mechanical Engineering (2005) In this thesis work, a mobile robot is designed to be used in search and rescue operations to help the human rescue workers. The difficult physical conditions in the ruins obstruct the movement. Therefore, it is aimed to design a search and rescue robot which can move easily on rough terrain and climb over the obstacles. The designed robot is made up of three modules. A connecting unit is designed that is situated between each module. This connecting unit which is composed of two universal and one revolute ...
Simulation modeling of shop floor activities for smes in virtual enterprises Bahtiyar, Mustafa; Kılıç, S. Engin; Department of Mechanical Engineering (2005) The globalization of the markets and the worldwide competition forces the SMEs to implement new technologies and organize themselves using new concepts in order to maintain their competitivity. This type of temporary alliance is called as Virtual Enterprise (VE). SMEs seem to be appropriate units for building this type of temporary alliances when their properties (such as flexibility, adaptability and agility) are taken into account. This study is concerned with the simulation modeling of shop floor activit...
Development of a web-based dynamic scheduling methodology for a flexible manufacturing cell using agent based distributed internert applications Alataş, Boran; Anlağan, Ömer; Department of Mechanical Engineering (2004) The increasing importance of computer leads to develop new manufacturing methods. One of the most important example; 3unmanned shop floor4 model aims, the mankind can work in jobs that they can be more efficient and more comfortable. As the base of this model, in Middle East Technical University Computer Integrated Manufacturing Laboratory (METUCIM) 3Agent Version 1.14 system is developed. Windows Distributed Internet Applications (DNA) modeling technique is used for the software development. In the develop...
Prediction of slip in cable-drum systems using structured neural networks KILIÇ, Ergin; Dölen, Melik (SAGE Publications, 2014-02-01) This study focuses on the slip prediction in a cable-drum system using artificial neural networks for the prospect of developing linear motion sensing scheme for such mechanisms. Both feed-forward and recurrent-type artificial neural network architectures are considered to capture the slip dynamics of cable-drum mechanisms. In the article, the network development is presented in a progressive (step-by-step) fashion for the purpose of not only making the design process transparent to the readers but also hig...
Design and simulation of a vapor compression refrigeration cycle for a micro refrigerator Yıldız, Seyfettin; Okutucu Özyurt, Hanife Tuba; Department of Mechanical Engineering (2010) Cooling of electronic equipments has become an important issue as the advances in technology enabled the fabrication of very small devices. The main challenge in cooling is the space limitation. The use of miniature refrigerators seems to be a solution alternative for the cooling problem. The objective of this study is to design and simulate a vapor compression refrigeration cycle for a micro-scale refrigerator. A MATLAB code is developed for the simulations. The four components of the refrigerator, namely,...
