In this paper we discuss the concept of co-adaptation between a human operator and a machine interface and we summarize its application with emphasis on two different domains, teleoperation and assistive technology. The analysis of the literature reveals that only in a few cases the possibility of a temporal evolution of the co-adaptation parameters has been considered. In particular, it has been...
In the field of painting and photography, composition guidelines are widely used under various circumstances in order to arouse people's aesthetic emotions. In this paper, we propose a method to evaluate the composition of a scene according to some certain rules, such as Rule of Third, Diagonal Composition and Triangle Composition. We propose an evaluation function with three parameters for each kind...
This paper presents a systematic mapping study based on literature and industrial survey related to assistive technologies for people with dementia. The world population of the ageing people is increasing both in developed and developing countries, so does the number of people with dementia. Consequently assistive technologies are getting much importance from academic researchers and industry as an...
Data-driven methods have lead to advances in multiple fields including robotics. These methods however have had limited impact on dexterous hand manipulation, partly due to lack of rich and physically-consistent dataset as well as technology able to collect them. To fill this gap, we developed a virtual reality system combining real-time motion capture, physics simulation and stereoscopic visualization...
This paper aims at developing a low-cost automation system to maintain the efficiency of solar panels connected in an array by providing an on demand cleaning. Wireless Sensor networks has been implemented to collect the data from individual panels. Monitoring data and information trends then will be used to trigger a robotic system to clean the surface of unclean panels.
Mobile robots are being used in various applications like space shuttles, intelligent home security, military applications or other service oriented applications where human intervention is limited. A robot has to understand its environment by analyzing the data to take the appropriate actions in the given environment. Mostly the data collected from the sensors on the robots are huge and continuous,...
Metacognition involves an ability to reflect upon a learning episode, understand what strategies provoked learning, and gauge one's current level of understanding. This paper details preliminary evidence regarding the University of Texas at El Paso (UTEP) Metacognitive Learners course, a pre-engineering course structured to develop metacognitive strategies and habits through scaffolded collaborative...
A pyroprocessing technology is being developed at the Korea Atomic Energy Research Institute. This technology development is conducted in a completely sealed argon cell where, as the cell is active, human operators' access to the in-cell is not possible owing to the nature of the toxicity of argon gas. Relevant processing equipment installed inside the cell should be operated and maintained in a fully...
In this paper, we introduce the Lehigh Ocean Research Craft Autonomous (LORCA) — a high performance USV with applications to surveillance and monitoring tasks. Compact (1.2 m), lightweight (5 kg) and robust (one-piece carbon fiber design), LORCA is capable of speeds of 80 kph (50 mph). It was also designed to be capable of operations in ocean waves, with self-righting ability in all sea states. We...
Maneuvering of unmanned underwater vehicle (UUV) is a challenging task especially when it is subject to hydrodynamic disturbances. In this paper, the heading control of UUV is considered. A comprehensive performance analysis based on proportional-integral-derivative controllers is presented. The simulations are performed on unmanned free swimming submersible and model obtained using real data from...
The purpose of the paper is to discuss human centered design implications for shared decision making between humans and autonomous systems in complex environments. Design implications are generated based on empirical results from two research paradigms. In the first paradigm, an intelligent agent (Robo Leader) supervised multiple subordinate systems and was in turn supervised by the human operator...
To be safe, mobile multi-robots systems need to be able to adapt to unexpected behaviours of robots as well as to exogenous changes in the environment. In this paper, we describe a novel approach for the development of multi-robots systems where robots collectively collaborate with each other to satisfy their goals and to adapt their behaviour in a collective way satisfying the overall system safety...
Robot Framework is a generic test automation framework based on keyword-driven and has been widely used in the automated testing of server. In this paper, Robot Framework is extended by test libraries to include some features in order to meet the demands of server testing, and the extended framework is used to execute the automated installation testing of server drives and firmware. Finally, analysis...
This paper presents a distributed world model that is able to adapt to changes in the Quality of Service (QoS) of the communication layer by online reconfiguration of perception algorithms. The approach consists of (a) a mechanism for storage, exchange and processing of world model data and (b) a feedback loop that incorporates reasoning techniques to adapt to QoS changes immediately. The latter introduces...
We are benefitting from the amazing changes taking place in terms of the Information and Communication Technology (ICT) and from the information devices that factored in these changes. As interest on health is increasing, effective monitoring, management, and protocol for the scientific and structured exercises are urgently called for. U-Fitness will be the realistic convergence system. Convergence...
The concept of proximity has been recently adopted in various fields of interest, with different meanings and implementations. In the Information Technology area, for example, proximity was used for analyzing user location and nearness to objects/people, and has already changed the way people interact with each other and with technology itself. In this field, the concept is becoming more important...
A supervisor's delayed intervention on a student's performance deficiencies seriously affects a research progress. Due to the demanding schedules of supervisors, it is a challenge for them to timely observe the performance deficiencies of the student. To mitigate this situation, we propose an agent-based system to enhance, control and manage the research supervision process. Specifically, the system...
Self-adaptation of Multi-agent systems requires dynamic decision making and planning at runtime. Modeling the contextual and executable requirements of such systems as planning actions and states, this paper proposes a requirements-driven planning approach to self-adaptation. The planning model includes the states of the system context and the actions describing the behaviors of its multiple agents,...
This work presents the design aspects of TRAVEE, a neuromotor rehabilitation system. The TRAVEE system relies on innovative concepts for improving the rehabilitation process and increasing the patient recovery rate. One such concept is to present the patient an augmented feedback as part of a learning process based on neuroplasticity. Most of the rehabilitation exercises are based on visual feedback...
Symbolic reasoners generate plans which are often not exploiting the robot capabilities and are sensitive to runtime disturbances. This work proposes a scheduler as an interface between a discrete, symbolic plan and a motion control based on constraint optimization. Acting as a local reasoner, the scheduler valuates a set of predicates to decide when an action will be executed. Given a task specification...
