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 applying ideas and principles from character animation. To this end, we modified the appearance and behaviors of a cobot, with minimal impact on its functionality and performance, and studied the extent to which these modifications improved its communication with and perceptions by human collaborators. Specifically, we aimed to improve the Appeal of the robot by manipulating its physical appearance, posture, and gaze, creating an animal-like character with a head-on-neck morphology; to utilize Arcs by generating smooth trajectories for the robot arm; and to increase the lifelikeness of the robot through Secondary Action by adding breathing motions to the robot. In two user studies, we investigated the effects of these cues on collaborator perceptions of the robot. Findings from our first study showed breathing to have a positive effect on most measures of robot perception and reveal nuanced interactions among the other factors. Data from our second study showed that, using gaze cues alone, a robot arm can improve metrics such as likeability and perceived sociability.

Design of a variable five-axes adjustable configuration robot manipulator YUCEL, AS; Ersak, Aydın (1994-04-14) A robot manipulator design is presented in this paper supplying a few kinematical configurations in a single structure which is in the mean time, reconfigurable for given tasks and hence making the level of flexibility and adaptability much higher for changing working environments
Intelligent Mesh For Self Reconfigurability of an Exoskeleton Arm Altintasi, Cagri; Erkmen, Aydan Müşerref (2014-08-27) This paper presents a new technique for a reconfigurable exoskeleton which consists of a connected network of small sized holonic robots enwrapping the human body limbs and more specifically, in this paper, the human arm. The connection control of the reconfigurable exoskeleton decides upon the necessity of a "disconnect", "reconnect" for chosen holons so as to balance any new load at the human joints. The intelligent controller carries out its decisions on the evaluation of stress at connections between ho...
Trust attribution in collaborative robots: An experimental investigation of non-verbal cues in a virtual human-robot interaction setting Ahmet Meriç, Özcan; Şahin, Erol; Acartürk, Cengiz; Department of Bioinformatics (2021-6) This thesis reports the development of non-verbal HRI (Human-Robot Interaction) behaviors on a robotic manipulator, evaluating the role of trust in collaborative assembly tasks. Towards this end, we developed four non-verbal HRI behaviors, namely gazing, head nodding, tilting, and shaking, on a UR5 robotic manipulator. We used them under different degrees of trust of the user to the robot actions. Specifically, we used a certain head-on neck posture for the cobot using the last three links along with the gr...
GENERATION AND ANALYSIS OF "BREATHING" AS AN HRI BEHAVIOR ON A COBOT Güneşdoğdu, Ali Nuri; Şahin, Erol; Acartürk, Cengiz; Department of Computer Engineering (2022-8-31) Collaborative robots, a.k.a cobots, are industrial robotic manipulators that have no built-in capabilities for social human-robot interaction (HRI). In the thesis, we implemented breathing for a cobot as a social behavior inspired by the secondary action animation principle. We automatically generated breathing of a cobot as HRI behavior with its waveform borrowed from human breathing; its amplitude and frequency are parametrized. We conducted a user study to measure the effect of parameters of breathing b...
DEVELOPMENT OF A SOCIAL REINFORCEMENT LEARNING BASED AGGREGATION METHOD WITH A MOBILE ROBOT SWARM Gür, Emre; Turgut, Ali Emre; Şahin, Erol; Department of Mechanical Engineering (2022-9-09) In this thesis, the development of a social, reinforcement learning-based aggregation method is covered together with the development of a mobile robot swarm of Kobot- Tracked (Kobot-T) robots. The proposed method is developed to improve efficiency in low robot density swarm environments especially when the aggregated area is difficult to find. The method is called Social Reinforcement Learning, and Landmark-Based Aggregation (SRLA) and it is based on Q learning. In this method, robots share their Q tables ...
