This thesis focuses on reshaping a previously detected human intention into a desired one, using contextual motions of mobile robots, which are in our applications, autonomous mobile 2-steps and a chair. Our system first estimates the current intention based on human trajectory depicted as location and detects body-mood of the person based on proxemics behaviors. Our previous reshaping applications have shown that the current human intention has to be deviated towards the new desired one in phases according to the readiness changes induced in the human. In our novel approach, Elastic network plans way points (intention transients) by searching trajectories in the feature space of previously learned motion trajectories each labeled with an intention. Our methodology aims at planning an “intention trajectory” (sequences of intention transients) towards the final goal. The initial way points possess destabilizing effects on the obstinance of the person intention making “the robot gain the curiosity of the person” and induces positive mood to the person making “the robot gain the trust of the person”. Each way point found by the elastic network is executed by moves of an adequate robot (here mobile 2-steps or chair) in adequate directions (towards coffee table, PC, library). After each robot moves, the resulting human intention is estimated and compared to the desired goal in the intention space. Intention trajectories are planned in two modes: the “confident mode” and the “suspicious mode”. This thesis work introduces our novel approach of planning trajectories based on elastic networks following these two modes.

Elastic Networks in Reshaping Human Intentions by Proactive Social Robot Moves Gorur, O. Can; Erkmen, Aydan Müşerref (2014-08-29) This paper focuses on reshaping a previously detected human intention into a desired one, using contextual motions of mobile robots, which are in our applications, autonomous mobile 2-steps stairs and a chair. Our system first estimates the current intention based on human heading and trajectory depicted as orientation and location. Our previous reshaping applications have shown that the current human intention has to be deviated towards the new desired one in phases. In our novel approach, Elastic network ...
A Grounded and contextualized web of concepts on a humanoid robot Çelikkanat, Hande; Kalkan, Sinan; Şahin, Erol; Department of Computer Engineering (2015) In this thesis, we propose a formalization for a densely connected representation of concepts and their contexts on a humanoid robot platform. Although concepts have been studied implicitly and explicitly in numerous studies before,our study is unique in placing the relatedness of concepts to the center: We hypothesize that a concept is fully meaningful only when considered in relation to the other concepts. Thus, we propose a novel densely connected web of concepts, and show how utilizing the relatedness o...
Design and implementation of a device to control a robotic arm by EMG signal Kandemir, Görkem; Eyüboğlu, Behçet Murat; Department of Electrical and Electronics Engineering (2013) In this study, an electromyogram (EMG)based human machine interface system is designed and implemented. System acquires EMG signals and processes them to generate commands to control a robotic arm. Different signal processing methodologies are investigated, realized, and compared. The thesis study includes design and implementation of an 8 channels electromyogram data acquisition system which is used to record raw EMG signals from operator’s muscles. The system transfers raw EMG data to control software via...
Slippage estimation of a two wheeled mobile robot using deep neural network Özçil, İsmail; Konukseven, Erhan İlhan; Koku, Ahmet Buğra; Department of Mechanical Engineering (2018) Mobile robot navigaiton is an important task for the operations of the mobile robots. Due to the wheel slippages, performance of the dead reckoning in estimating speed of the robot and the position of the robot is not sufficient. To overcome the errors in navigation estimates, usage of the recurrent deep neural networks is porposed. Neural networks are used to understand the behaviour of the linear and nonlinear systems. Since wheel-ground interaction will be modeled with non-linear models and the estimatin...
Human aware navigation of a mobile robot in crowded dynamic environments Hacınecipoğlu, Akif; Konukseven, Erhan İlhan; Department of Mechanical Engineering (2019) As mobile robots start operating in dynamic environments crowded with humans, human-aware and human-like navigation is required to make these robots navigate safely, efficiently and in socially compliant manner. People can navigate in an interactive and cooperative fashion so that, they are able to find their path to a destination even if there is no clear path leading to it. This is clearly a dexterity of humans. But the mobile robots which have to navigate in such environments lack this feature. Even perf...
