An estimated discrete time model from analog servo motor with limited state information was obtained. The process is divided in two main parts. First, we build diagram blocks consisting DC motor and its position controller. Next, we find the whole transfer function derived from the diagram blocks. Second, we obtained sampled-data from experiment to estimate the coefficients of simplified discrete...
This paper presents an innovative implementation of a radio communication system, which is able to transmit analog and digital data. The main goal of this project is to implement a multiprocessor system, based on the FPGA technology, which can control multiple radio transceivers. In this configuration allow a various possibilities of communication: analogue (voice) communication and data transmission...
In this video, the FRC (Future Robotic Computer) and its demonstrations are introduced. The FRC is a new concept of computer by combining cameras as input device and image projectors as output device. It also has actuators to control the input and the output devices. The selected demonstrations will show the applications of various situations.
This paper investigates user perceptions of continuous identity as agents migrate between different embodiments. It reports an experiment seeking to establish whether migrating or not migrating the interaction memory of the agent would affect the user's perception of consistent agent identity over different embodiments. The experiment involved a treasure hunt in which a virtual agent migrated from...
In several research areas, e.g. in the field of human-robot interaction, ratings or questionnaires are applied using offline and online methods. An argument for the use of online methods is the efficiency. By using the Internet, data can be collected much faster than in an offline experiment and the administration effort is very low. The goal of our study was to find out, if there is a difference...
This paper presents the development of a low-cost experiment board used AVR microcontroller for in class at KMITL to starter board. Caused of this family chipset are easy for development, be convenience and more database. There is the main reason for developed starter board to be more compacted and more simplified. The board microcontroller edit by C language, power supplied by computer USB port....
In this paper, we propose a real-time vision-based hand posture recognition approach, based on appearance-based features of the hand poses. Our approach has three main steps: Preprocessing, Feature Extraction and Posture Recognition. Additionally, a new hand posture dataset called HandReader is created and introduced. HandReader is a dataset of 500 images of 10 different hand postures which are 10...
In recent years, much research has been devoted to the construction of public-private key pairs; on the other hand, few have synthesized the visualization of the producer-consumer problem. Given the current status of efficient archetypes, leading analysts famously desires the emulation of congestion control, which embodies the key principles of hardware and architecture. In our research, we concentrate...
Marine phenomena such as algal blooms can be detected using in situ measurements onboard autonomous underwater vehicles (AUVs), but understanding plankton ecology and community structure requires retrieval and analysis of water specimens. This process requires shipboard or manual sample collection, followed by onshore lab analysis which is time-consuming. Better understanding of the relationship between...
Using mobile robots in the engineering education is a well-accepted and practical way to teach in the undergraduate programs. In the literature, several different cases are reported to show the adaptation of some robots. This paper describes how mobile robots and basic image processing algorithms might be combined in the MATLAB programming environment to provide a more efficient learning and simulation...
Hemiparesis is a frequent outcome of brain damage (e.g., after stroke). There is a diversity of rehabilitation systems which have been designed for restoring the upper or lower limb functions in individuals with disabilities resulting from spinal cord injury (SCI), stroke and muscle dystrophy. These systems are based either on functional electrical stimulation (FES) or rehabilitation robots and haptic...
It is well established that acquiring large amount of range data with vision sensors can quickly lead to important data management challenges where processing capabilities become saturated and preempt full usage of the information available for autonomous systems to make educated decisions. While sub-sampling offers a naïve solution for reducing dataset dimension after acquisition, it does not capitalize...
In the centenary year of Turing's birth it is appropriate to explore the relationship between Computational and Human Intelligence along the path that he proposed over 60 years ago. In many way, he saw clearly what the issues were, although there were some that he missed or underestimated. We approach the problem of Human-level Computational Intelligence from two perspectives: the aspects of human...
Microcontrollers play an increasingly important role in applied computing systems ranging from your toaster to deep space probes. A myriad of objects are embedded with microcontrollers and sensors and have the ability to communicate. The resulting Internet of Things promises to revolutionize information pathways. Are we prepared for this new reality? Within universities, microcontroller courses are...
In applications of the navigation and control of unmanned ground vehicles in a cross-country environment and tele-driving a rover on the unknown lunar surface for scientific exploration, human-computer interactive path planning and planned path tracking is a significant way of teleoperation. In this paper, we use the method based on Rapidly-Exploring Random Trees (RRTs) to solve the robot path planning...
This paper describes the design methodology behind the design of an underground autonomous mine safety platform. The robot is intended for use as an underground safety platform in gold mines of South Africa, where right after a blast the hanging wall (roof) and poles need to be inspected and cleared before the crew can enter. The robot platform has to deal with rough terrain and the steep slope of...
Children really enjoy painting. Painting is not only full of fun but also beneficial for children to further develop their physical skills (e.g., hand eye coordination, fine motor skills, and gross motor skills), express their creativity, boost their self-confidence, etc. On the other hand, storytelling is also a joyful and educational activity for children. In this paper, we develop an interactive...
We present a Sketch-Based Interface that allows non-expert users to create an animation from just pencil and paper. The interface works as a fast mockup tool for creating animations - turning the user's freehand 2D sketches into 3D animations. To facilitate animation construction in offline or computer-scarce scenarios, special emphasis is placed on paper-based instead of tablet-based sketches. The...
Student competitions are widespread across all academic disciplines, and are often touted as a means to motivate and educate students. Competitions may be internal within a single class or course, or vie school against school as regional, national, or international competitions and exist at all levels including 9–12 grades. These competitions have different formats and focuses such as vulnerability...
GORGE is the name of a research tool developed for investigations into playful development of technology competence. As a research tool, it has been employed several times in varying settings and application scenarios always quite successfully. Set up as a browser game, GORGE is now invading private homes. Playing GORGE may result in a gain of technology competence provided that particular aspects...
