Simple robot applications can be run on a single computer, but when it comes to more complex applications or multiple mobile robots, software distribution becomes important. When structuring mobile robot systems and applications, distribution has to be considered on various levels. This paper proposes to distinguish between real-time level, system level, application level and regarding the world model...
This paper presents a comparison of Mobile Robots localization methods through Artifical Neural Networks in omnidirectional images. After an overview about Mobile Robotics, this work focuses on omnidirectional vision. The motivation for this work is the implementation and comparison of feature extraction techniques that can be used in omnidirectional images seeking invariance to rotation and building...
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...
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...
Accurate localization and navigation are indispensable for mobile agents to walk in large-scale indoor public space, such as intelligent building and disaster rescue. In this paper, an intelligent localization and navigation system called ISILON is designed and developed. The system consists of a mobile terminal and multiple sensor nodes (also called landmarks) installed in the environment. The mechanism...
In this paper, we introduced some methods which are to resolve the problems to design and implement a self-balancing two-wheel mobile platform based on CompactRIO, two digital DC servo motors and other devices. And we also used LabVIEW to receive data to display the curve and to save data by Microsoft Excel for farther analyses. Using these methods, we have designed a two-wheel mobile platform to...
As we all know that it is easy to understand the thoughts of traditional grid method, if handled inappropriately, the calculation will be extremely large and a suitable path can not be found. The paper has introduced an new path planning method based on the grid model, which does not need complicated calculation and promise to provide an appropriate path to guide the mobile robot to reach the goal...
During last years Linux started to climb the market of operating systems (OSs), and Ubuntu, derived by Debian OS, has become a good alternative to common OSs like Windows XP or Vista. The mobile robotics scientific community makes use of Linux based OSs to avoid the lack of stability that affects Microsoft OSs, especially when real time conditions must be satisfied. In this paper we present the Linux...
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...
With the development of Internet technology, the Web-based teleoperation of mobile manipulators becomes possible. Fuzzy control is to control an object according to the experts' experiences, and its design does not depend on the mathematical model of the control object. It is suitable for the control of the mobile manipulator, which is a complex system. This paper designed a fuzzy control system of...
In this paper, we introduce and evaluate ScaleMesh, a scalable miniaturized dual-radio wireless mesh testbed based on IEEE 802.11b/g technology- ScaleMesh can emulate large-scale mesh networks within a miniaturized experimentation area by adaptively shrinking the transmission range of mesh nodes by means of variable signal attenuators. To this end, we derive a theoretical formula for approximating...
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...
