Exercise dosage is proven to be an important factor in the physical treatment. Robot assistive approach can improve the rehabilitation quality and evaluate patient's recovery quantitatively. This paper presents kinematic structure, assistive control system, and integrated F/T sensor for an upper limb rehabilitation robot. By using the human arm dynamic, there are three rehabilitation modes presented...
Recently, elderly people who live alone in a room is increased. But, it is hoped that the elderly people keep good health. To keep good health for elderly people, a human should act autonomously. Frankl's psychology discusses the importance of external value that is picked up by external stimuli. Therefore, it is expected that a person would act autonomously if a person find the meaning and value...
The purpose of this study is to develop a robot that plays an alto recorder and sounds like a human playing an alto recorder. In recent years, the development of robots that entertain people by playing a variety of musical instruments has been observed. Many of these robots have specific features, for example, artificial lips for playing wind instruments. However, particularly when performing special...
A mobile robot used in home or office has to not only search the shortest path but also perform the path planning to respect human movement. In this study, several sensors are distributed in the environmental side, and humans walking route is observed. Then, we propose a “Human Frequency Map (HFM)” that is grid map based on the observed human position. By using the HFM, the proposed path planning...
Nano-robots are the robots that are simply known as that controllable machines at the nano (10−9) meter or molecular scale, composed of nano-components. More specifically, nano robotics refer to the still largely hypothetical nanotechnology engineering discipline of designing and building nano robots. Even though the field of nano robotics is fundamentally different from that of the macro robots due...
The purpose of this half-day workshop is to explore the role of social gaze in human-robot interaction, both how to measure social gaze behavior by humans and how to implement it in robots that interact with them. Gaze directed at an interaction partner has become a subject of increased attention in human-robot interaction research. While traditional robotics research has focused work on robot gaze...
We are undertaking the development of a brain computer interface (BCI) [1] for control of an upper limb prosthetic. Our approach exploits electrical neural activity data for motor intent estimation, and eye gaze direction for target selection. These data streams are augmented by computer vision (CV) for 3D scene reconstruction, and are integrated with a hierarchical controller to achieve semi-autonomous...
The use of autonomous robots in organizations is expected to increase steadily over the next few decades. Although some empirical work exists that examines how people collaborate with robots, little is known about how to best design interfaces to support operators in understanding aspects of the task or tasks at hand. This paper presents a design investigation to understand how interfaces should be...
In this paper we investigate principles of swarm control that enable a human operator to exert influence on and control large swarms of robots. We present two principles, coined selection and beacon control, that differ with respect to their temporal and spatial persistence. The former requires active selection of groups of robots while the latter exerts a passive influence on nearby robots. Both...
In this study, we investigate and characterize haptic interaction in human-to-human handovers and identify key features that facilitate safe and efficient object transfer. Eighteen participants worked in pairs and transferred weighted objects to each other while we measured their grip forces and load forces. Our data show that during object transfer, both the giver and receiver employ a similar strategy...
This study investigates whether the temperature of a robot's hand can affect perceptions of the robot as a companion. Our research empirically analyzes the responses of 39 individuals randomly assigned to one of three conditions: (1) holding a warm robot hand or (2) holding a cold robot hand or (3) not holding a robot hand. The effects of this simulated ‘human touch’ on HRI were examined in the context...
A major challenge is to design a robot that can attract and control human attention in various social situations. If a robot would like to communicate a person, it may turn its gaze to him/her for eye contact. However, it is not an easy task for the robot to make eye contact because such a turning action alone may not be enough in all situations, especially when the robot and the human are not facing...
This paper presents the propensities of preference for Human Robot Interaction (HRI) according to different personalities and facial expressions of humans and robots. This study is based on two types of personalities: extroverted and introverted. According to the personality, the facial expressions are distinguished to express extroversion and introversion. The design of experiment is a 3 (participant's...
Robots are currently being used in and developed for critical HRI applications such as search and rescue. In these scenarios, humans operating under changeable and high-stress conditions must communicate effectively with autonomous agents, necessitating that such agents be able to respond quickly and effectively to rapidly-changing conditions and expectations. We demonstrate a robot planner that is...
We present a system that enables a humanoid robot to imitate complex whole-body motions of humans in real time. For recording the human motions, any sensor system capable of inferring the joint angle trajectories can be used. In our work, we capture the human data with an Xsens MVN motion capture system consisting of inertial sensors attached to the body. Our framework converts the human joint angles...
In this paper, we present our work designing a robot that explains an exhibit to multiple visitors in a museum setting, based on ethnographic analysis of interactions between expert human guides and visitors. During the ethnographic analysis, we discovered that expert human guides employ some identical strategies and practices in their explanations. In particular, one of these is to involve all visitors...
In this paper, we present the adaptation of a sensorless (in De Luca's sense [1], i.e., without the use of extra sensors,) collision detection approach previously used on robotic arms to mobile wheeled robots. The method is based on detecting the torque disturbance and does not require a model of the robot's dynamics. We then consider the feasibility of developing control by physical interaction strategies...
As an early behavioral study of what non-verbal features a robot tourguide could use to analyze a crowd, personalize an interaction and maintain high levels of engagement, we analyze participant gaze statistics in response to a robot tour guide's deictic gestures. There were thirty-seven participants overall, split into nine groups of three to five people each. In groups with the lowest engagement...
A survey of 873 undergraduate students was conducted to understand which individual factors affect subjects' attitudes toward robots. A third of participants (N =284) were exposed to a humanoid robot, another third (N= 293) to a doggy robot, and the remaining third (N=296) to an android. Results showed that in the humanoid condition individuals recognize more humanlike characteristics in robots than...
Networked robotic applications enable robots to operate in distant, hazardous, or otherwise inaccessible environments, such as search and rescue, surveillance, and exploration applications. The most difficult challenge which persists for such systems is that of supporting effective human-robot interaction, as this usually demands managing dynamic views, changeable interaction modalities, and adaptive...
