The term Conformal Printing refers to 3D printing onto uneven surfaces. Whilst some very high priced solutions exist for known uneven surfaces, where the toolpath is generated in advance, based on CAD data of the object to be printed onto, there is nothing available yet for conformal printing onto unknown uneven surfaces that are scanned on-the-fly. A low-cost prototype named ‘InSPIREd’ was recently...
More than 5% of Thai people have strabismus. Strabismus is known as cross-eyed or wall-eyed because the visual field angle of two eyes is not parallel. The amblyopia disease is the cause of strabismus in kids. Strabismus can be completely cured if the strabismus screening can be made in early stage. Currently, strabismus screening includes methods such as Hirschberg test, cover test and Krimsky test,...
For many years as a child, I did nothing but play with Lego. Eventually I had children of my own, who had a nice Lego collection themselves, but nothing you’d need machinery to sort. That changed after a trip to Legoland in Denmark.
The focus of the project is to create new approaches to the study of the past through the use of innovative aero-space technologies to measure, analyse and reconstruct the ancient landscape and its remaining natural and anthropic traces. The équipe, based at the University of Padua, is constituted by archaeologists, egyptologists, mechanical and software engineers, physicists and computer scientists...
This paper presents the initial work toward deep space robotic applications. Humanoid robots as astronauts can experience gravity differences, hazardous environmental conditions, extreme latency communications, and lack of energy sources while on deep space missions. Such constraints provide a challenge in the development of software, hardware, and experiments for space humanoid robots. This paper...
Swarms of drones are increasingly being requested to carry out missions that cannot be completed by single drones. Particularly in the field of civil security, strong needs emerge in terms of surveillance and observation of hostile, distant or extended areas. Currently, existing solutions do not meet this demand, as they are generally based on too heavy infrastructures or over-processing, without...
We developed a software program, BradykAn, that computes motion characteristics and processes data acquired from compact optical motion capture systems (MoCap) such as Optitrack V120: Trio which provides accurate and easily acquired information about 3-dimensial movement. BradykAn has implemented algorithms and protocols for the evaluation of Unified Parkinson's Disease Rating Scale hand motor tests...
Visuomotor integration (VMI), the use of visual information to guide motor planning, execution, and modification, is necessary for a wide range of functional tasks. To comprehensively, quantitatively assess VMI, we developed a paradigm integrating virtual environments, motion-capture, and mobile eye-tracking. Virtual environments enable tasks to be repeatable, naturalistic, and varied in complexity...
Situational awareness involves the timely acquisition of knowledge about real-world events, distillation of those events into higher-level conceptual constructs, and their synthesis into a coherent context-sensitive view. We explore how convergent trends in video sensing, crowd sourcing and edge computing can be harnessed to create a shared real-time information system for situational awareness in...
Small Unmanned Aircraft Systems (sUAS) are already revolutionizing agricultural and environmental monitoring through the acquisition of high-resolution multi-spectral imagery on-demand. However, in order to accurately understand various complex environmental and agricultural processes, it is often necessary to collect physical samples of pests, pathogens, and insects from the field for ex-situ analysis...
Distributed teaching of engineering subjects requires the accessibility of equipment and devices over the Internet The authors have developed an effective environment for remote renewable engineering laboratories and distance learning. This paper covers the background, methods, evaluation and analysis of remote laboratory model designed and implemented to consolidate data, video and audio feeds gathered...
Rapid and low power computation of optical flow (OF) is potentially useful in robotics. The dynamic vision sensor (DVS) event camera produces quick and sparse output, and has high dynamic range, but conventional OF algorithms are frame-based and cannot be directly used with event-based cameras. Previous DVS OF methods do not work well with dense textured input and are designed for implementation in...
This paper puts forward a Human-Machine Interaction robot which can play chess games with human. Based on the existing Computer Games and Robot technology, the robot can accomplish more functions. The robot can recognize the human players' wrong, and send a signal to remind human players. Windows environment could run Artificial Intelligence software base on C language and LabVIEW. And the software...
microMVP is an affordable, portable, and open source micro-scale mobile robot platform designed for robotics research and education. As a complete and unique multi-vehicle platform enabled by 3D printing and the maker culture, microMVP can be easily reproduced and requires little maintenance: a set of six micro vehicles, each measuring 8 × 5 × 6 cubic centimeters and weighing under 100 grams, and...
Bio-mimetic robots can interact with groups of animals in bio-hybrid systems to study their behaviour by producing calibrated stimuli and by analysing their responses. Integrating a group of robots into a group of animals to mimic their behaviour is challenging, both in terms of robotic hardware design and robot control. In particular, the robots must be able to react in real-time to the animal changes...
With the emergence of IoT (Internet of Things) smart cities have assumed a crucial role in providing intelligent services in real time to residents and visitors, by integrating services such as smart transportation, smart parking and smart people management. By introducing emergent properties as the system's new behaviors or new structures, the system gains another higher level of intelligence that...
This paper presents an adaptive video encoder that can be used to compare the behavior of different adaptation strategies using multiple actuators to steer the encoder towards a global goal, composed of multiple conflicting objectives. A video camera produces frames that the encoder manipulates with the objective of matching some space requirement to fit a given communication channel. A second objective...
We present a preliminary study to understand how apps evolve in their permission requests across different releases. We analyze over 14K releases of 227 Android apps, and we see how permission requests change and how they are used. We find that apps tend to request more permissions in their evolution, and many of the newly requested permissions are initially overprivileged. Our qualitative analysis,...
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...
In the paper we present a method for increasing the quality of views synthesized with typical Depth-Image-Based Rendering (DIBR) view synthesis algorithms. In the proposed idea the resolution of input real views and corresponding depth maps is doubled before the view synthesis. After the synthesis, the resolution of a synthesized view is downsampled back to the original resolution. This approach is...
