Direct perception of traversibility affordance on range images through learning on a mobile robot
Uğur, Emre; Şahin, Erol; Department of Computer Engineering (2006)
In this thesis, we studied how physical affordances of the environment, such as traversibility for a mobile robot, can be learned. In particular, we studied how the physical properties of the environment, as acquired from range images obtained from a 3D laser scanner mounted on a mobile robot platform, can specify the traversibility affordance. A physics based simulation environment is used during exploration trials, where the traversibility affordances and the relevant features for each behavior are learne...
A fluid dynamics framework for control of mobile robot networks
Paç, Muhammed Raşid; Erkmen, Aydan Müşerref; Department of Electrical and Electronics Engineering (2007)
This thesis proposes a framework for controlling mobile robot networks based on a fluid dynamics paradigm. The approach is inspired by natural behaviors of fluids demonstrating desirable characteristics for collective robots. The underlying mathematical formalism is developed through establishing analogies between fluid bodies and multi-robot systems such that robots are modeled as fluid elements that constitute a fluid body. The governing equations of fluid dynamics are adapted to multi-robot systems and a...
Mobility and power aware data interest based data replication for mobile ad hoc networks
Arslan, Seçil; Bozyiğit, Müslim; Department of Computer Engineering (2007)
One of the challenging issues for mobile ad hoc network (MANET) applications is data replication. Unreliable wireless communication, mobility of network participators and limited resource capacities of mobile devices make conventional replication techniques useless for MANETs. Frequent network divisions and unexpected disconnections should be handled. In this thesis work, a novel mobility and power aware, data interest based data replication strategy is presented. Main objective is to improve data accessibi...
A Parametric study on planetary gear dynamics
Öztürk, Veysel Yalın; Özgüven, Hasan Nevzat; Ciğeroğlu, Ender; Department of Mechanical Engineering (2018)
An extended parametric study is performed for Planetary Gear Train (PGTs) dynamics. A purely torsional, non-linear time-varying model is used for the dynamic simulation of PGTs. Time-dependent stiffness functions are calculated by using dedicated contact mechanics software that is specialized in gears. Multi-term Harmonic Balance Method (HBM) is used for the solution of the model. The fundamental modal characteristics of PGTs are explored. The initial parametric studies are performed for the basic dynamic f...
Influences of interplanetary magnetic field on the variability of aerospace media
Yapıcı, Tolga; Tulunay, Yurdanur; Department of Aerospace Engineering (2007)
The Interplanetary Magnetic Field (IMF) has a controlling effect on the Magnetosphere and Ionosphere. The objective in this work is to investigate the probable effects of IMF on Ionospheric and Geomagnetic response. To fulfill the objective the concept of an event has been created based on the polarity reversals and rate of change of the interplanetary magnetic field components, Bz and By. Superposed Epoch Method (SPE) was employed with the three event definitions, which are based on IMF Bz southward turnin...
