There is no doubt that microblog is becoming one of the most forceful powers over the Internet, with billions of users all over the world. Making use of the well-connected microblog network, a highly influential user (or opinion leader) can be of great importance, with commercial, social, or even political values. In this paper, we discuss the conditions and methods to become an opinion leader based...
This paper describes a new methodological approach and robot system to trigger more prosocial human reactions towards a robot by transferring social-psychological principles from human-human interaction to human-robot interaction (HRI). The main idea is to trigger increased helpfulness by proactively creating similarity through dynamic emotional adaption of the robot to the mood of the human. This...
Future robots need to autonomously acquire motor skills in order to reduce their reliance on human programming. Many motor skill learning methods concentrate on learning a single solution for a given task. However, discarding information about additional solutions during learning unnecessarily limits autonomy. Such favoring of single solutions often requires re-learning of motor skills when the task,...
In a soccer match, a cooperative behavior emerges from the combined execution of simple actions by players. A cooperative behavior can be planned if players are previously committed to its execution prior to its start or unplanned otherwise. The ability to reproduce some of these behaviors can be useful to help a team achieve better performances.
GORGE is the name of a research tool developed for investigations into playful development of technology competence. As a research tool, it has been employed several times in varying settings and application scenarios always quite successfully. Set up as a browser game, GORGE is now invading private homes. Playing GORGE may result in a gain of technology competence provided that particular aspects...
This document presents a novel approach to control the attack behavior of a team of simulated soccer playing robot of the Robocup 2D category. The presented approach modifies the behavior of each player only when in the state "controlling the ball". The approach is based on a modified Q-Learning algorithm that implements a continuous machine learning process. After an initial learning phase,...
Using robots to reward and stimulate children doing tasks together can be helpful in improving their social skills. Robots implemented 3 types of behavior scenarios — imitate, enhance and counteract — in a collaborative game of teaching robots perform movements shown by hand gestures. The paper presents a novel account of ASD symptoms based on the interplay of empathic concern and empathic accuracy...
Artificial Gene Regulatory Networks (GRN) usually simulate cell behavior in developmental models. However, since 2003, GRN based controllers have been applied to robots to solve problems with few sensors and actuators. In this paper, we present our first steps toward an effective GRN-based controller for intelligent agents in video games. We will also introduce an experiment, the Radbot, where a robot...
In our study, we will look at how the substantial context-embedded authentic tasks had been done under a high-interactive gaming structure in classroom basis. We analyzed the difference of intrinsic motivation (enjoyment, perceived competence, pressure, etc) and learning effectiveness between team players and individual players in the game-based learning environments.
This paper is concerned with the pursuit problem of indoor pursuit-evasion games (PEGs) with multiple pursuers and one fast evader. The system is implemented in multiple mobile robots with the ability of wireless communication. A model of the pursuit problem of fast evader in indoor PEGs is presented to consider the case that the exact position of evader is unavailable to the pursuers. To solve this...
There are millions of people that regularly play Go in many countries around the world. Played by two players, Black and White, the stones of their colors are placed consecutively on an empty intersection of a square grid. In order to support beginners of Go to enjoy and concentrate on the game, this paper proposes a fuzzy markup language (FML)-based emotional expression system and applies it to computer...
This paper presents progress in the development of a robotic system for post-stroke upper limb rehabilitation. It is a portable, lower cost, actuated upper limb robotic rehabilitation device, which is being developed to meet the needs of stroke therapists and their patients. The developed system provides force feedback for haptic rehabilitation, applying both resistive and assistive forces for more...
Affective computing is computing that relates to, arises from, or deliberately influences emotions. It has lots of applications in the next generation of human-computer interfaces. We have proposed a closed-loop affective computing system, which includes affect recognition, affect modeling, and affect control. Because emotions include both intra-personal uncertainty, which is the uncertainty a person...
Pursuit evasion problems, in which evading targets must be cleared from an environment, are encountered in surveillance and search and rescue applications. Several works have addressed variants of this problem in order to study strategies for the pursuers. As a common trait, many of these works present results in the general form: given some assumptions on the environment, on the pursuers, and on...
We develop a technique to automatically generate a control policy for a robot moving in an environment that includes elements with partially unknown, changing behavior. The robot is required to achieve an optimal surveillance mission, in which a certain request needs to be serviced repeatedly, while the expected time in between consecutive services is minimized. We define a fragment of Linear Temporal...
This paper describes the transfer of theories on prosocial behavior from Social Psychology to human-robot interaction (HRI) in terms of helpfulness shown by humans towards a robot. Theoretical foundations are given, and relevant influence factors for prosocial behavior are defined. The paper provides an overview on how these factors can be transferred to HRI and are implemented in two experimental...
In this paper, we consider the problem of capturing an omnidirectional evader using a Differential Drive Robot in an obstacle free environment. At the beginning of the game the evader is at a distance L > l from the pursuer. The pursuer goal is to get closer from the evader than the capture distance l. The goal of the evader is to keep the pursuer at all time farther from it than this capture distance...
In 2010 a group of students at Embry-Riddle designed and built a robot capable of playing the popular videogame “Rockband.” The goal of the robot was to compete against human players in a score duel. Development of the robot presented many challenges that had to be overcome in order for the robot to be successful. This paper discusses the solutions to those challenges and the results of testing the...
Image process is a key process to the fish-like robot polo game. A good image process system is one of the basic elements of winning the game. But in the past games, it was before the game begun that we made effort to adjust the parameters to adapt to the environment. Obviously, this kind of method couldn't meet the reality of the changeable competition environment. This paper proposes a self adaptive...
As robots become increasingly capable and autonomous, the role of a human operator may be to supervise multiple robots and intervene to handle problems and provide strategic guidance. In such cases, the extent to which HRI tools support the human supervisor's situational awareness (SA) and ability to intervene in an appropriate and timely fashion will constrain the scale of operations (e.g., the number...
