Flying Robots Designed to Form Emergency Network
European academic researchers have developed a constellation of robust, lightweight flying robots using wireless communications that could be employed in mapping, remote sensing, ground searches, and other similar operations.
The robots consist of a flying-wing airframe, with neither fuselage nor tail. They are propelled by a single electric motor running on a battery capable of 30 minutes.
The aircraft have an 80-centimeter wingspan, weigh about 500 grams, and are built with inexpensive, lightweight yet strong polypropylene foam. Their airspeeds can range between 8 and 20 meters per second (between 18 and 45 miles per hour), and they can fly as high as several kilometers, although a swarm generally stays below 150 meters to avoid conflicts with general aviation.

The Development of a Full-Field Image Ranger System for Mobile Robotic Platforms
A mobile robot's ability to rapidly and accurately measure variables in its external environment is vital to its ability to function in that environment. A variety of sensors are available to provide a robot with such information but typically have a trade-off between update rate, accuracy and field of view.
Full-field range imaging, where every object in the sensor's field of view is ranged, offers both a wide field of view and accurate range measurements at update rates greater than existing sensor technologies with similar accuracy and fields of view.

Range-based Navigation System for a Mobile Robot
In this paper we present an algorithm for path planning in a fixed range-only beacon field. We define and calculate entropy values for regions of interest and provide a method for finding "safe," low-entropy paths between regions. We go on to describe a robotic system for performing range-based localization experiments, developed using inexpensive off-the-shelf components. Our system uses a commercial robot as a mobile platform and custom acoustic beacons for ranging.
In this paper we investigate approaches that can allow a mobile robot to exploit information provided by wireless devices already present in the environment. We examine a case in which the robot is assumed to be carrying out a routine task that requires it to navigate arbitrarily between a finite number of specified locations, e.g. for the transporting of goods in a warehouse application.
Under these circumstances, we are interested in identifying safely navigable regions and routes in the instrumented environment that can allow the robot to successfully satisfy the requirements of its task. By safely navigable regions we mean areas where the robot’s pose uncertainty is relatively low.

Network-Centric Control for Multirobot Teams in Urban Search and Rescue
Theories from Network-centric Warfare (NCW) distinguish between network-centric and platform--centric orientations to sensing and control. In platform-centric control the operator(s) access and focus on data through platforms they control, a robot's camera, for example. In network-centric control the operator(s) do not access data through platforms but instead through the network without regard to where information originated. The conventional human role in sophisticated information gathering systems is usually as both commander (of platforms) and perceiver. Human sensory and perceptual capabilities, however, far outstrip our abilities to process information frequently making our perceptual function more critical to the mission. The use of human operators as "perceptual sensors" is standard practice for both UAVs and ground robotics where humans are called upon to "process" camera video to find targets and assist in navigation. This paper traces the evolution of an experimental human-multirobot system for Urban Search and Rescue in which operators navigated robots while searching for victims in streaming video to a network--centric version in which they search recorded video asynchronously.
Utilizing Geographic Information System Data for Unmanned Aerial Vehicle Position Estimation
For many sensing applications Unmanned Aerial Vehicles (UAVs) can provide a lightweight and highly portable solution. Inevitably they may encounter malfunctions, the most serious of which may require the UAV to land as soon as possible. From a safety prospective it is insufficient to assume the UAV can safely reach a previously determined safe landing site.
It is therefore desirable to utilize a reliable source of knowledge such as Geographic Information System (GIS) data to aid in autonomous safe landing site detection. However, before this knowledge can be exploited the UAVs position must be known.
This position is commonly estimated using GPS the failure of which may be the very reason an abort command has been issued. Presented in this paper is a method of UAV position estimation which can be executed in the event of GPS failure.
Preliminary results are presented based on aerial imagery from the Antrim Plateau region of Northern Ireland which indicate potential in the approach used.

Behavior-based Fuzzy Control for Indoor Cleaning Robot Obstacle Avoidance Under Dynamic Environment
This paper describes an indoor cleaning robot coverage path to avoid obstacle based on behavior fuzzy controller under dynamic environment. The robot measures the distance between the robot and obstacle with ultrasonic sensors and infrared range sensors. The behavior architecture has three levels behaviors: emergency behavior, obstacle avoidance behavior, and task oriented behavior.
The task oriented behavior is the highest level behavior with the lowest priority, and has two subtasks: wall following and path covering. The middle level behavior is obstacle avoidance. And the lowest level is an emergency behavior with the highest priority behavior. The simulation results demonstrate that each behavior works correctly.

The Importance of Eye Gaze and Head Pose to Estimating Levels of Attention
This paper explores, from a theoretical and technical point of view, the role of head rotation and eye gaze directionality to the human perception of attention from non-verbal cues. We have annotated two different versions of the same dataset, in order to correlate the above parameters with the degree people have considered people in the dataset pay attention to a hypothetical task they have in front of them.
Based on our findings, we investigate the role of eye gaze directionality in relation to head rotations and, based on previous studies, we developed an algorithm for estimating attention levels from head pose, eye gaze and facial feature spatial locations.
With the help of our AI system and people's annotation, we have made a first attempt towards quantifying the role of each cue to the overall estimation of attention. One of the important properties of the technical part of this work is that all systems we used were non-intrusive and did not demand any personal training or calibration phase, constituting themselves ideal for Game playing. Knowing the behavioral state of a player can be of vital importance for adapting the game design during interaction, or building personal profiles, leading to appropriate game features aiming at maximizing player satisfaction.
