In our societies, there is a steady increase in the elderly population. These people need a constant supervision to perform simple tasks at their homes, which is sometimes not possible. This lack of permanent attention sometimes results in the late detection of emergency situations. Therefore, it is judicious to promote technology that helps to detect and react in case of emergency situations. In...
Generally, industrial robot has been used in the automate producing process and the repetitive process on behalf of human. Recently, the interest in the human-robot cooperative industrial robot which can work together with human through physical interaction in the same space has been increased. Human-robot cooperation technology can allow to combine work intelligence of human with high performance...
Reflexology is a kind of assisting physical care through massaging or applying pressure to parts of the feet where will reflect an image of the human body in order to improve general health of the human. Based on this principle, we propose a new application of 7-DOF(degree of freedom) redundant manipulator to do the massaging work for human feet with the tactile sensor equipped to the end-effector...
We previously proposed a model for a handshake approaching motion with a voice greeting and developed a handshake robot system that applied the proposed model for embodied interaction with humans. The handshake robot system was fabricated by considering the average size of a human arm. However, small-size embodied interaction robots are required for use in homes. Therefore, in this study, a small-size...
Human robot teams combining the complementary capabilities of robots and humans towards solving potentially complex service tasks are gaining wide spread popularity. Many of these tasks will involve close interactions between the robot and the human it serves thereby making safety a crucial parameter. Erroneous interaction that inevitably arises between human and the robot causes accidents in service...
Knowledge-based systems are advanced systems for representing complex problems that use artificial intelligence to solve these problems. They incorporate a database of expert knowledge designed to facilitate the knowledge retrieval in response to specific queries, along with learning. In this paper we present a knowledge based system designed to increase the efficiency of the tasks executed by a robot...
One of the main recent achievements in engineering is description of complex products and their physical environment in a single object model. This model has capabilities to serve engineering from the first specification of a product to recycling. New research programs were needed in order to establish a new style of engineering where engineers communicate model creation and application procedures...
Combining the intelligent and situation dependent decision making capabilities of a human with the accuracy and power of a robot, performance of many tasks can be improved. The human-robot collaboration scenarios are increasing. Human-robot interaction is not only restricted to the humanoid robots interacting with the humans or to the mobile service robots providing different services but also industrial...
Engineering in product definition traditionally concentrates on building structures of parts and assemblies. Other objects such as analysis results, manufacturing methods, and equipment control programs are mapped to part and assembly definitions. This style of engineering has been realized in model and simulation based product development. Product data management systems as extensions to product...
The Modular Modeling Design is a modeling method based on a new way of thinking. It combines the characteristic of digital and physical modeling, and fully takes a variety of modeling conditions into account for building the anchors of design when the designer are modeling the product. In the modeling process, use the designing anchors to form the boundary line of different shapes on the basic model...
The purpose of this paper is to develop a companion robot, which can display facial expressions and recognize human faces. With the 12 degrees of freedom, the robot can generate various facial expressions. In addition, a face-recognition method is proposed based on combining two complementary matching algorithms (a single-image matching algorithm and a sequential-image matching algorithm). We have...
We developed a 1 DOF power assist robot for lifting objects. We hypothesized that human's perception of weight due to inertial force might be different from the perceived weight due to gravitational force for lifting an object with a power assist robot. We established psychophysical relationships between the actual weights and the power-assisted weights for the objects lifted with the robot, and also...
Current applications of mobile robots in urban search and rescue (USAR) environments require a human operator in the loop to help guide the robot remotely. Although human operation can be effective, the unknown cluttered nature of the environments make robot navigation and victim identification highly challenging. Operators can become stressed and fatigued very quickly due to a loss of situational...
Allowing robots to communicate naturally with humans is an important goal for social robotics. Most approaches have focused on building high-level probabilistic cognitive models. However, research in cognitive science shows that people often build common ground for communication with each other by seeking and providing evidence of understanding through behaviors like mimicry. Predictive State Representations...
There are many different forms of human-robot interactions, allowing a team of humans and robots to take advantage of skills of each team member. A developing area of research is focused upon the potential of robot swarms working in emergency settings. In particular we consider a swarm of robots that are capable of supporting and enhancing fire fighting operations co-operatively. This paper outlines...
A robot's head is important both for directional sensors and, in human-directed robotics, as the single most visible interaction interface. However, designing a robot's head faces contradicting requirements when integrating powerful sensing with social expression. Furher, reactions of the general public show that current head designs often cause negative user reactions and distract from the functional...
People perform daily activities in many different ways. When setting a table, they might use a tray, stack plates, stack cups on plates, leave the doors of a cupboard open when taking several items out of it. Similarly flexible behavior is desired when mobile robots perform household tasks. Moreover, they should perform actions in a way that they are accepted by the people, for example by showing...
Domestic service tasks require three main skills from autonomous robots: robust navigation in indoor environments, flexible object manipulation, and intuitive communication with the users. In this report, we present the communication skills of our anthropomorphic service and communication robots Dynamaid and Robotinho. Both robots are equipped with an intuitive multimodal communication system, including...
Robots do not have any capability of taking moral responsibility. At the same time industrial robotics is entering a new era with ??intelligent?? robots sharing workbench with humans. Teams consisting of humans and industrial robots are no longer science fiction. The biggest worry in this scenario is the fear of humans losing control and robots running amok. We believe that the current way of implementing...
The objective of this study is to examine the effect of intergroup relations on robots through comparison with other objects. In an experiment, participants watched eight stimuli drawn from four types of objects (people vs. robots vs. animals vs. products) according to two types of intergroup relations (in-group vs. out-group) and rated each stimuli in terms of familiarity, reliability, and preference...
