Robots designed for navigation use one or more of the three basic locomotion configurations viz rotational devices such as wheels or crawler tracks, legs and articulated bodies. In this paper we present the design and characterization of a hybrid locomotion mechanism for mobile robots navigating in unstructured and possibly treacherous environments. We fuse the advantages offered by the three classes...
Performing general human behavior by experts' navigation is expected to be realized as wearable and ubiquitous technologies and computing develop further. For example, the user of the behavior navigation system will be able to conduct first aid treatment as an expert would. We proposed and developed the Wearable Behavior Navigation System (WBNS) using Augmented Reality (AR) technology. By using the...
Social interaction and group coordination are important factors in the simulation of human crowd behavior. To date, few simulation methods have been informed by models of human group behavior from the social science studies. In this paper we advance a computational model informed by Common Ground (CG) Theory that both inherits the social realism provided by the CG model and is computationally tractable...
Nowadays, remote control of robots (telerobots) is mainly based on two models; the first one is used for controlling robot that work in well-defined environments; The second model concerns the monitoring and surveillance robots acting in an unknown and dynamic workspace. The disadvantages of these models are the lack of real human dynamic control of the robot tasks and the functionally limited available...
In this video we briefly illustrate the progress and contributions made with our mobile, indoor, service robots CoBots (Collaborative Robots), since their creation in 2009. Many researchers, present authors included, aim for autonomous mobile robots that robustly perform service tasks for humans in our indoor environments. The efforts towards this goal have been numerous and successful, and we build...
In the near future, robots will exist in our home, office, hospital, school and all other public places. In other words, robots have to work and share environments with human. However, there exist many invisible social rules or social protocols in human society. For example, people usually stand in a line to access certain services. It seems that there is a social force or a “spatial effect” which...
This paper presents an interface that allows a human user to specify a desired path for a mobile robot in a planar workspace with noisy binary inputs that are obtained at low bit-rates through an electroencephalograph (EEG). We represent desired paths as geodesics with respect to a cost function that is defined so that each path-homotopy class contains exactly one (local) geodesic. We apply max-margin...
To minimize the maritime accidents, it is universal agreed that the ship's officers who manoeuvring the ship must be well-trained. A ship bridge simulator is always proved to be one of the best ways to achieve the training objective, as it enables the navigator to expose to many realistic experiences. This study proposes a consideration of human performance (navigator) in such an environment by using...
Large-format displays, in particular tiled displays, remain actively used and researched today after almost two decades since their conception. Many government, academic, and commercial entities have invested considerably in the construction and use of large-format displays. During this time we have developed new applications but have also discovered faulty assumptions. This position paper evaluates...
This paper proposes the development of an autonomous navigation robot with hand-cleaning service in indoor environments. To navigate in unknown environments and provide service, the robot is with several intelligent behaviors including wall-following, obstacle avoidance, autonomous navigation, and human detection. A laser-sensor-based approach is used in the wall-following and obstacle avoidance behavior...
Pervasive computing technologies can benefit the injured, disabled or elderly people in their daily lives, and smart wheelchair has been a representative of this kind of technologies. However, most existing smart wheelchairs have limitations on extensibility and flexibility of building new functionalities. One big reason is they are just stand-alone ones considering other wheelchairs and surrounding...
The aim of cognitive augmentation is to expand the intrinsically limited human's cognitive abilities caused by cognitive impairment or disability. In order to assist the human's limited cognitive ability, we are trying to develop a human augmented cognition system that aims to provide the appropriate information actively corresponding to what user intents to do. In this paper, we mainly address the...
Virtual networking method for multi-robot navigation is proposed. This method is suitable for the collaboration of the robots that supports human workers in offices, factories, or disaster areas. In this method, virtual nodes and their forwarding tables are constructed on each robot according to DSDV routing protocol. These virtual information navigates the robot to its destination. The data volume...
In this work, we present and evaluate an ensemble approach towards the modeling and mitigation of congestion in multi-agent robotic systems operating in a dynamic environment. In particular, we consider the problem of congestion management between robots and robots and human agents in an automated factory or warehouse. The main contribution of this work is the development of appropriate ensemble models...
The current paper is an investigation towards understanding the navigational performance of humans on a network when the 'landmark' nodes are blocked. We observe that humans learn to cope up, despite the continued introduction of blockages in the network. The experiment proposed involves the task of navigating on a word network based on a puzzle called the word morph. We introduce blockages in the...
Infrared Sensors are widely used nowadays on Aircrafts (rotary and fixed wing) to help pilot's activities. The infrared information of the surrounding area are used mainly for two different purposes: Navigation and Search & Track-While-Scan. Navigation functions, commonly identified with the name of Imaging Modes, are devoted to aid pilots in conjunction with advanced human machine interfaces...
A fundamental requirement of non-player characters (NPCs) in today's computer games is to be able to move through a complex virtual world in an intelligent way. Pathfinding or path planning techniques are used by games developers to determine suitable routes, during gameplay, from a starting location to a goal position. These techniques make use of graphs to efficiently represent the game world. Navigation...
Emergency management systems (EMS) are important and complex examples of Cyber-Physical-Human systems that are deployed so as to optimise the outcome of an emergency from a human perspective. They use sensor networks, networked decision nodes and communications with evacuees and first responders to optimise the overall Quality of Service to benefit primarily human beings in terms of survival, health...
The way pedagogical aspects are expressed in the user interface of virtual learning environments greatly impacts the learning process, in particular the interactions between students and other human or non-human actors in the learning environment. This paper presents an evaluation of how the interactions for learning are expressed in the user interface of an IMS Learning Design (LD) runtime environment...
