Accessibility for people with motor impairments is limited in direct manipulation-reliant software applications, especially in those that utilize geospatial technology. In this paper, we demonstrate an alternative method to interact with geospatial web applications such as Google Street ViewTM and Google MapsTM using Brain Computer Interface technology. We conducted a user study for our web application...
The faithful and flexible simulation of mobile robotic platforms with different application-specific sensing capabilities will become increasingly important in order to test a wide range of scenarios without having to run real missions. Current research focuses primarily on the mobility dynamics of such systems, and to this end a lot of work has already been done to support the simulation of various...
The growing need of Disaster management requires some specialties in sophisticated technologies. Navigating an Unmanned Aerial Vehicle (UAV) in an unknown indoor environment is a complex task. This work tries to implement an autonomous system, which navigates the Low-cost Quadcopter with an on-board computer, sensors and Ground station which carries out a spatially consistent probabilistic model for...
Navigation is a fundamental problem that relates to localization and positioning for a humanoid robot Nao. Odometry is the one of many techniques that able to solve it. Nao humanoid robot actually doesn't have an odometry module by itself, and odometry sensors that currently available on it and can be used is only IMU module. An odometry sensor that quite interesting in recent times, usually for fusioning...
The task of planetary exploration poses many challenges for a robot system, from weight and size constraints to sensors and actuators suitable for extraterrestrial environment conditions. In this work, we present the Light Weight Rover Unit (LRU), a small and agile rover prototype that we designed for the challenges of planetary exploration. Its locomotion system with individually steered wheels allows...
In this paper the performances (in terms of accuracy) of an hybrid positioning technique, that brings together an image based recognition approach and MEMS (Micro Electro-Mechanical Systems) technology, will be investigated. The image recognition based (IRB) positioning has already been well investigated in the past and represents a good technology for navigation in GNSS denied environment, like indoor...
This article deals with a problem of creating and managing medium to large scale software projects aimed at promoting research activities in the field of autonomous mobile robotic systems. We will demonstrate on an example of such systems how we identified critical parts of the project and how can be created simple but powerful software architecture suitable for complex management of all subsystems...
In the paper, we propose a new method for the virtual view synthesis called as Multiview Synthesis. In our approach, virtual views are synthesized using two neighboring real views, but the disoccluded areas are not inpainted, but filled by the information from the further real views — additional views, traditionally not included in the view synthesis. The whole synthesis is performed with triangles...
This paper introduces NASA's new free-flying robot, Astrobee, especially focusing on its avionics and perching subsystems. Astrobee is a cube-shaped autonomous robot designed for various missions on the International Space Station (ISS). Its major goal is to offload routine and repetitive work from the ISS crews and assist their science activities. Astrobee is also designed for scientists to use it...
This paper presents a novel small unmanned aerial system which can operate independently and navigate using visual sensors. The basis of the system is a 600 gram quadrotor platform with sonar, inertial sensors and a camera. All processing is performed onboard the vehicle on a lightweight and powerful computer. Vehicle navigation is provided by a two part system. A Bierman Thornton extended Kalman...
This paper addresses the development and implementation of a testbed for object's manipulation by using unmanned aerial vehicles AR.Drone and the VICON Cameras System. Such testbed allows the user to choose among two development environments to perform aerial manipulation establishing a communication with LabVIEW, ROS and the C++ Qt library; thus, the user can employ the development environment more...
Within the EUROFLEETS project, and linked to the EMODNet and Geo-Seas European projects, GLOBE (Global Oceanographic Bathymetry Explorer) is an innovative and generic software combining all necessary functionalities for cruise preparation, for collection, linking, processing and display of scientific data acquired during sea cruises, and for exporting data and information to the main marine data centers...
This work presents a combination of software and hardware that makes aerial autonomy substantially more accessible both in terms of programmatic complexity and in terms of cost. We use the ARDrone quadrotor helicopter and Willow Garage's Robot Operating System software infrastructure to demonstrate several autonomous tasks. Using vision as the sole aerial sensor, we demonstrate point-to-point navigation,...
The AUVSI Autonomous Surface vehicle event is a student-based competition where teams design, build and compete with fully autonomous surface vessel. These vehicles are required to preform many different tasks that vary from competition to competition but the ability to navigate channels marked by red and green markers and perform GPS based navigation is always a constant. Embry-Riddle Aeronautical...
We investigate user experiences when using augmented reality (AR) as a new aid to navigation. We integrate AR with other more common interfaces into a handheld navigation system, and we conduct an exploratory study to see where and how people exploit AR. Based on previous work on augmented photographs, we hypothesize that AR is used more to support wayfinding at static locations when users approach...

This article describes a new interaction device for surgical navigation systems — the so-called navigation mouse system. The idea is to use a tracked instrument of a surgical navigation system like a pointer to control the software. The new interaction system extends existing navigation systems with a microcontroller-unit. The microcontroller-unit uses the existing communication line to extract the...
Augmented Reality (AR) is the technology of adding virtual objects to the real scenes through enabling the addition of missing information at real life. As the lack of resources is a problem that can be solved through AR, this paper represents and explains the usage of AR technology in what can be named Augmented Reality Student Card (ARSC) for serving the education field. ARSC uses single static...
We propose a visual recognition system for robotic applications in which distance to the visual objects can change a lot (for instance, trying to recognize a distant object learned from a short distance). Our system takes advantage of a single pan-tilt camera controllable in zoom and focus. Focus control allows to detect plans of sharpness in the scene and indirectly to compute a distance. Hence,...
Stereo vision system is a practical method for depth gathering of objects and features in an environment. This paper presents the depth evaluation in selected region of disparity mapping for stereo vision mobile robot using block matching algorithm. This region is a reference sight of the stereo camera and stereo vision baseline is based on horizontal configuration. The block matching technique is...
