In recent years, mobile data gathering in wireless sensor networks has attracted much interests in the research community. However, despite extensive efforts, many of previous work in this area lies only in theory and evaluates network performance with computer simulations, which leaves a large gap from reality. In this paper, we present the design and implementation of a general purpose, flexible...
The article touches aspects of security in Wireless Sensor Networks. It begins with a review and classification of existing types of threats and protection methods. The main part of the paper presents the results obtained during development of a threat detection system for WSN network. The described approach is based on a mobile platform which allows separation of security mechanisms and the software...
Modern robotic systems tend to get more complex sensors at their disposal, resulting in complex algorithms to process their data. For example, camera images are being used map their environment and plan their route. On the other hand, the robotic systems are becoming mobile more often and need to be as energy-efficient as possible; quadcopters are an example of this. These two trends interfere with...
Design and software development of embedded computer-based robotic systems have been the main aim of this paper. For this aim, the Lego Mindstorms NXT robot platform which is supported by Microsoft Robotics Studio (MSRS) software development environment and equipped with ARM7 microprocessor, are used. Software development studies are made on it. Embedded computer systems are analysed generally and...
Nowadays, location based applications increasingly used in many areas. Although outdoor navigation software applications are mature and widely used, improvements are required for indoor navigation. The applications such as guidance of disabled people, applications for security, visitor tracking, address mapping, the organization of services, automatic tourist guidance etc. are also needed for indoor...
Mobile sensor networks are often composed of agents with weak processing capabilities and some means of mobility. However, recent developments in embedded systems have enabled more powerful and portable processing units capable of analyzing complex data streams in real time. Systems with such capabilities are able to perform tasks such as 3D visual localization and tracking of targets. They are also...
The work introduced in this paper was performed as part of the FP7 INTRO (Marie-Curie ITN) project. We describe the activities undertaken towards the development of a field robotic assistant for a Search and Rescue application. We specifically target a rubble clearing task, where the robot will ferry small pieces of rubble between two waypoints assigned to it by the human. The aim is to complement...
This paper presents a new university course combining theoretical lectures with a robot competition. The main intention is to offer a practical course including hands-on experiences being close to current research topics in the field of mobile robotics. For this purpose, a commercial mobile robot is equipped with state of the art sensors, allowing autonomous execution of manipulation tasks. The course...
The increase of greed in people has paved way to civilwars and natural disasters. A swift action has to be taken in the relief work of the aftermath of earthquake affected areas, such that any delay in the rescue could lead the death toll to rise. The same can be applied to war fields too. The proposed research focuses on human beings who are alive and struggling for their lives either in the war...
This paper presents an idea and a construction details of the tiny sensor-based robot-vehicle as a mobile hardware platform for Wireless Ad-hoc Sensor Networks (WSN). The main scope of the research was design and implementation of the mobile platform, allowing the WSN nodes to autonomously change its location in active way. The designed platform had been integrated with sensor node and provided with...
The mobile humanoid Rollin'Justin is a versatile experimental platform for research in manipulation tasks. Previously, different state of the art control methods and first autonomous task execution scenarios have been demonstrated. In this video two new applications with challenging task requirements are presented. One is the catching of one or even two flying balls using all of Justin's degrees of...
This paper describes our on-going efforts toward developing heterogeneous, cooperative systems technologies. In particular, we present the role of unmanned mobile ground systems (robots) in a heterogeneous sensor network, consisting of two unmanned aircraft, a mobile ground robot, and a set of four stationary ground sensors, performing an intelligence, surveillance, and reconnaissance (ISR) mission...
This paper describes the prototype design and development of a tele-operated robotic system. The robotic system consists of a robotic arm operating on top of a mobile base system. The robot is constructed using cheap and easily obtainable materials and serves as a platform to test and investigate control techniques and mechanical designs. The robot is controlled via an onboard computer which communicates...
This paper describes an interactive social agent platform which examines anthropomorphic robot features in the mobile phone usage context. Our system is smart phone based robot agent that operates on a mobile network and co-located ad-hoc networks. It helps remote users communicate interactively with each other through the robotic interface which utilizes facial expressions and body gestures. In this...
A number of mobile manipulators have been custom engineered and built in labs worldwide. Mobile manipulators could become much more prevalent if they were assembled from commercially available components instead of being locally engineered and built. In this paper, we describe some tests and the integration steps in putting together power source, computers, and distributed software systems for integrating...
The advent of more portable and affordable sensing devices has facilitated the study of rehabilitation robotics. Critical to the further development of therapies and interventions are low-cost, easy-to-use devices that can be applied in clinical and home care settings. In this paper, we present a low-cost motion capture system that relies on the opensource Player/Stage software development environment,...
The author describes the experience of designing and implementation of a mobile robotic platform. In the future, the platform will be used in various robotics and cybernetics research projects, including implementation of a control system that utilizes FPGA-based devices and participation in robotics competitions: Robots Olimpiad, Mobile Robots Festival, and possibly Eurobot.
For a set of mobile sensor network, a precise localization is required in order to maximize the utilization of mobile sensor network. As well, mobile robots also need a precise localization mechanism for the same reason. In this paper, we showed a combination of various localization mechanisms. Localization can be classified in three big categories: long distance localization with low accuracy, medium...
The field of electronic noses and gas sensing has been developing rapidly since the introduction of the silicon based sensors. There are numerous systems that can detect and indicate the level of a specific gas. We introduce here a system that is low power, small and cheap enough to be used in mobile robotic platforms while still being accurate and reliable enough for confident use. The design is...
Currently, robots are being used as teaching tools and can be found in K-12 and college classrooms. The primary appeal associated with employing robots is that they tend to capture the attention of the target audience and thereby facilitate the learning process. While there are numerous robotic kits on the market today, few can be used to teach both high-level concepts in computer science and engineering...
