Article describes basic decisions on construction of the fire robot based on a quadcopter. The fire robot carries out patrol of a premise for detection of a fire and its liquidation. The basic technical requirements are formulated for the fire robot. The block diagram and constructive blocks for robot realization are offered. Hardware of the fire robot movement control system and method of video signal...
The objective of this paper has been the development of a prototype of articulated robotic arm and the implementation of a control strategy through gesture recognition (Leap Motion Sensor), by means the natural movement of the forearm and hand. The series of advances relative to the control techniques have caused that the robotics it has also introduced as an educational complement in obligatory basic...
In this paper a new control software for automatic pick&place machines is presented. The software prepares the files necessary production and is responsible for controlling the pick&place machine via serial connection. It is designed for use in teaching and prototyping environments. The program structure allows for rapid adaptation to other machine models.
Pedestrian areas use lighting systems with output at the mesopic level, which is situated between the photopic and scotopic. Studies have shown surrounding luminance effect on peripheral vision and its magnitude of the effect is larger than that of the foveal luminance. This study aims to examine this proposed model using real night time lighting conditions experienced by pedestrians in dark and narrow...
Flashover occurs more easily on contaminated transmission line insulators, which causes great economic losses and has bad effects on power system stability. An accurate and safe detection of insulator contamination grades is required. In this paper, a new method is proposed to discriminate insulator contamination grades using visible light images. Firstly, ZSW-10/4 insulators are smeared in different...
Multimedia is the main support for online learning materials and the size of multimedia learning materials is growing with the popularity of online programs offered by Universities. Ultimate Course Search (UCS) is a tool that aims to provide efficient search of course materials. UCS integrates slides, lecture videos and textbook content into a single platform with search capabilities. The keywords...
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, we focus on the problem of RGB color space identification from a single image. At the moment, RGB color spaces are widely adopted in photography for image producing. The problems with respect to color space identification, such as to get the consistent printing or displaying quality on screen devices and software applications and prevention of multimedia unauthorized usage(shown or...
The article describes the architecture and use cases of the vehicles external control unit (BBCU — BODY & BOARD CONTROL UNIT) for the vehicle communication within global traffic systems including traffic security and safety (Car2Car, Car2Infrastructure concepts supported), IoT architectures as well as Smart Cities applications. The BBCU is an embedded system optionally supplemented with graphical...
Sign language is a way of communication bypeople suffering from hearing loss. Around 360 million people globally suffer from disabling hearing loss out of which 328 million are adults and 32 million children. Hearing impairment greater than 40 decibels (dB) in the better hearing ear is referred as a disabling hearing loss. Thus, with increasing number of people with deafness, there is also a rise...
This paper presents a modular designed dynamic positioning (DP) experiment system. Three modules are designed for the DP experiment system, which are onboard computer module, position sensing module and onshore control computer module. The hardware system and software are introduced. A PC/104 computer is used as the main controller of the onboard computer system, and an ARM microcontroller is used...
This paper presents an Augmented Interactive Reality book (AIR) application, aimed to enhance the reading experience of adult-learners by incorporating Augmented Reality (AR) technology to improve the interaction of normal books. Various features and characteristics of Augmented Reality (AR) were applied to the chosen book, "My Vision" written by H.H. Sheikh Mohammed Bin Rashid Al Maktoum,...
Multiprocessor SoCs (MPSoCs) are deployed in intelligent Rear View Camera Systems (iRVCS) for capture, analytics and display. iRVCS, mounted near the car's exterior surface, are subject to direct sunlight for prolonged time. At high junction temperatures (Tj) iRVCS completely shuts down for thermal protection resulting in complete loss of visibility. The paper focuses on techniques to detect such...
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...
In this paper, a design is proposed of a Pupillometer, which comprises of a spectacle mounted Pi-NoIR Infrared Camera system to detect pupil dilation, constriction and saccades of the eyes of the patient. These parameters are tracked using IR Illuminators mounted on spectacle frame that will be interfaced to a Raspberry Pi 2 Development board. The Raspberry Pi 2 is programmed to map the visual acuity...
This paper focuses on a method of constructing panoramas from a quadcopter, and a new mosaicing sub-problem when the scene contains significant regions of vacant spaces. These vacant spaces yield little to no features to match input images and hence challenge existing mosaicing techniques. We describe a framework that is able to handle this unique input by leveraging the availability of the inertial...
Forensic experts, police officers and others working with forensic video analysis can benefit from more �intelligent� video handling tools, such as automatic event/face detection, for instance to help search the relevant video footage prior to the actual case work. The ideal would be to have access to tailor-made software, based on state of art knowledge in fields such as soft biometrics, gait recognition,...
The vision of smart cities and IoT is an environment blanketed with interconnected, software-enabled devices. Unlike software installed on personal devices, however, people may not know about services in the environment, or may not even be the intended users. People lack a unified way to discover software services in a smart city infrastructure, and the current device-centric approach to IoT is inconsistent...
We present four raycast-based techniques that determine the transformation between a depth camera's coordinate system and the coordinate system defined by a rectangular surface. In addition, the surface's dimensions are measured. In contrast to other approaches, these techniques limit additional hardware requirements to commonly available, low-cost artifacts and focus on simple non-laborious procedures...
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...
