This thesis outlines the methodology and experiments associated with the reshaping of human intention via based on the robot movements in Human-Robot Interactions (HRI). Although works on estimating human intentions are quite well known research areas in the literature, reshaping intentions through interactions is a new significant branching in the field of human-robot interaction. In this thesis, we analyze how previously estimated human intentions change based on his/her actions by cooperating with mobile robots in a real human-robot environment. Our approach uses the Observable Operator Models (OOMs) and Hidden Markov Models (HMMs) designed for the intelligent mobile robotic systems, which consists of two levels: the low-level tracks the human while the high-level guides the mobile robots into moves that aim to change intentions of individuals in the environment. In the low level, postures and locations of the human are monitored by applying image processing methods. The high level uses an algorithm which includes learned OOM models or HMM models to estimate human intention and decision making system to reshape the previously estimated human intention. Through this thesis, OOMs are started to be used at the human-robot interaction applications for first time. This two-level system is tested on video frames taken from a real human-robot environment. The results obtained using the proposed approaches are compared according to performance towards the degree of reshaping the detected intentions.

Implementation of a closed-loop action generation system on a humanoid robot through learning by demonstration Tunaoğlu, Doruk; Şahin, Erol; Department of Computer Engineering (2010) In this thesis the action learning and generation problem on a humanoid robot is studied. Our aim is to realize action learning, generation and recognition in one system and our inspiration source is the mirror neuron hypothesis which suggests that action learning, generation and recognition share the same neural circuitry. Dynamic Movement Primitives, an efficient action learning and generation approach, are modified in order to fulfill this aim. The system we developed (1) can learn from multiple demonstr...
Imitation of human body poses and hand gestures using a particle based fluidics method Tilki, Umut; Erkmen, İsmet; Erkmen, Aydan Müşerref; Department of Electrical and Electronics Engineering (2012) In this thesis, a new approach is developed, avoiding the correspondence problem caused by the difference in embodiment between imitator and demonstrator in imitation learning. In our work, the imitator is a fluidic system of dynamics totally different than the imitatee, which is a human performing hand gestures and human body postures. The fluidic system is composed of fluid particles, which are used for the discretization of the problem domain. In this work, we demonstrate the fluidics formation control s...
Reshaping human intention in Human-Robot Interactions by robot moves A comparative analysis of HMM and OOM methods Durdu, Akif; Erkmen, Aydan Müşerref; Yilmaz, Alper (John Benjamins Publishing Company, 2019-01-01) This paper outlines the methodology and experiments associated with the reshaping of human intentions based on robot movements within Human-Robot Interactions (HRIs). Although studies on estimating human intentions are well studied in the literature, reshaping intentions through robot-initiated interactions is a new significant branching in the field of HRI. In this paper, we analyze how estimated human intentions can intentionally change through cooperation with mobile robots in real Human-Robot environmen...
Momentum transfer continuum between preshape and grasping based on fluidics Özyer, Barış; Erkmen, İsmet; Erkmen, Aydan Müşerref; Department of Electrical and Electronics Engineering (2012) This dissertation propose a new fluidics based framework to determine a continuum between preshaping and grasping so as to appropriately preshape a multi-fingered robot hand for creating an optimal initialization of grasp. The continuum of a hand preshape closing upon an object that creates an initial object motion tendency of the object based on the impact moment patterns generated from the fingers is presented. These motion tendencies should then be suitable for the proper initiation of the grasping task....
Software development for man-machine interface for an industrial robot Cengiz, Mahir Cihan; Kaftanoğlu, Bilgin; Department of Mechanical Engineering (2003) In this study, a robotic software, which controls the robot, is developed. The robot considered is a six degree of freedom robot and it is designed and manufactured in METU. User can send the robot anywhere in space within its workspace, in any orientation. Forward and inverse kinamatics can be executed according to the needs. Simulation framework is embedded into the software for the 3D visualisation of the robot. Any movements can be simulated on the screen. Software also generates the path for the given ...
