Designing Social Cues for Collaborative Robots: The Role of Gaze and Breathing in Human-Robot Collaboration
Terzioglu, Yunus; Mutlu, Bilge; Şahin, Erol (2020-01-01)
In this paper, we investigate how collaborative robots, or cobots, typically composed of a robotic arm and a gripper carrying out manipulation tasks alongside human coworkers, can be enhanced with HRI capabilities by apply...
Learning Context on a Humanoid Robot using Incremental Latent Dirichlet Allocation
Çelikkanat, Hande; Orhan, Guner; Pugeault, Nicolas; Guerin, Frank; Şahin, Erol; Kalkan, Sinan (Institute of Electrical and Electronics Engineers (IEEE), 2016-03-01)
In this paper, we formalize and model context in terms of a set of concepts grounded in the sensorimotor interactions of a robot. The concepts are modeled as a web using Markov Random Field (MRF), inspired from the concept...
Vision-Based Detection and Distance Estimation of Micro Unmanned Aerial Vehicles
Gökçe, Fatih; Üçoluk, Göktürk; Şahin, Erol; Kalkan, Sinan (MDPI, ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND, 2015-9)
Detection and distance estimation of micro unmanned aerial vehicles (mUAVs) is crucial for (i) the detection of intruder mUAVs in protected environments; (ii) sense and avoid purposes on mUAVs or on other aerial vehicles a...
Integrating Spatial Concepts into a Probabilistic Concept Web
Celikkanat, Hande; Şahin, Erol; Kalkan, Sinan (2015-07-31)
In this paper, we study the learning and representation of grounded spatial concepts in a probabilistic concept web that connects them with other noun, adjective, and verb concepts. Specifically, we focus on the prepositio...
Staged Development of Robot Skills: Behavior Formation, Affordance Learning and Imitation with Motionese
Ugur, Emre; Nagai, Yukie; Şahin, Erol; ÖZTOP, ERHAN (2015-06-01)
Inspired by infant development, we propose a three staged developmental framework for an anthropomorphic robot manipulator. In the first stage, the robot is initialized with a basic reach-and-enclose-on-contact movement ca...
Learning and Using Context on a Humanoid Robot Using Latent Dirichlet Allocation
Celikkanat, Hande; Orhan, Guner; Pugeault, Nicolas; Guerin, Frank; Şahin, Erol; Kalkan, Sinan (2014-10-16)
In this work, we model context in terms of a set of concepts grounded in a robot's sensorimotor interactions with the environment. For this end, we treat context as a latent variable in Latent Dirichlet Allocation, which i...
Verb concepts from affordances
Kalkan, Sinan; Dağ, Nilgun; Yuerueten, Onur; Borghi, Anna M.; Şahin, Erol (John Benjamins Publishing Company, 2014-01-01)
In this paper, we investigate how the interactions of a robot with its environment can be used to create concepts that are typically represented by verbs in language. Towards this end, we utilize the notion of affordances ...
The learning of adjectives and nouns from affordance and appearance features
Yürüten, Onur; Şahin, Erol; Kalkan, Sinan (SAGE Publications, 2013-8-22)
We study how a robot can link concepts represented by adjectives and nouns in language with its own sensorimotor interactions. Specifically, an iCub humanoid robot interacts with a group of objects using a repertoire of ma...
Co-learning nouns and adjectives
Orhan, Guner; Olgunsoylu, Sertac; Şahin, Erol; Kalkan, Sinan (2013-08-22)
In cognitive robotics community, categories belonging to adjectives and nouns have been learned separately and independently. In this article, we propose a prototype-based framework that conceptualize adjectives and nouns ...
Relating affordances with verbs, nouns and adjectives Sǎglarlik ile fiiller, isimler ve sifatlarin iliş kilendirilmesi
Kalkan, Sinan; Yürüten, Onur; Şahin, Erol (2013-04-26)
Learning and conceptualizing words categories such as verbs, nouns and adjectives in language based on sensorimotor interactions of a robot is a challenging topic in cognitive robotics. In this article, we summarize our ap...
