The article is focused on problematic of the middle size wheeled 6×6 UGV development (approx. 1100kg), lessons learned, achieved results and its system integration in the digitized battlefield. Based on previous experiences with UGV systems, there were identified fundamental factors of tactical and technological requirements, which converge to a set of priorities, including some (routine) processes...
This paper presents a method for recognizing the state of a user's brain activity by applying fuzzy reasoning to signals measured by a two-channel compact near-infrared spectroscopy (NIRS) device and investigates its feasibility and characteristics with regards to developing a compact brain-machine interface that utilizes NIRS. Distance-type fuzzy reasoning with membership functions of a singleton...
As the sliding parameter of track is hard-to-measure when Agricultural Tracked Robot (ATR) is moving in complicated farmland environment, an estimation method for sliding parameters of ATR based on UKF is proposed. A kinematics equation and a measurement equation of ATR are deduced by kinematics principle, and then the precision position parameters of ATR is calculated. Sliding parameters which cannot...
Path planning for autonomous parking control is difficult and complicated because of its non-holonomic constraints. We proposed the parking path planner KPP (Korea University Path Planner) in our prior work. The purpose of this paper is to prove the advantages of KPP through quantitative and qualitative analyses. Numerical simulations have been carried out for comparison. This paper shows that KPP...
The purpose of this study was to examine the structural relationship of influential variables for the utilization of r-learning in class by kindergarten teachers and the paths of the variables in an attempt to accelerate the utilization of r-learning among kindergarten teachers and provide some information on the vitalization of r-learning in early childhood education. The subjects in this study were...
In this paper, we describe the development of a leg with a rotational joint that mimics the elastic characteristics of the leg of a running human. The purpose of this development was to realize the dynamics of human running, the analysis of which has revealed that the motion of the leg can be modeled by a compression spring and that of the leg joint by a torsion spring. We, therefore, assumed that...
The relationship between muscles' electrical activity and body movements is of special importance in many medical applications. In this study, for the first time, we plan to evaluate the efficiency of time-delay parallel cascade identification (TDPCI) to predict jaw motion using Electromyography (EMG) signals recorded from two masticatory muscles, namely masseter and temporalis. The Obtained results...
One of the seminal attributes of mobile robots is to navigate accurately in a workspace executing tasks such as collision and obstacle avoidances and target convergence. Use of landmarks has become one of the popular methods to aid in navigation. In this paper, we present a new solution of landmark aided navigation using the Lyapunov-based Control Scheme. We assume a priori knowledge of a set of landmarks...
"A fair measurement is possible only under one unknown", which is an iron principle in instrumentation technology. In other words, it is difficult to evaluate two unknowns simultaneously, through the measurement of just one output from sensor. The main topic is to evaluate cell deformability through a micro fluidic channel. When a cell passes through a micro channel whose size is a bit smaller...
This paper presents a cable-driven ankle rehabilitation system (C-DARS). The proposed system is designed to easily apply the ankle rehabilitation treatment for multi-users. A small and light connecting part is attached to an orthosis worn by a patient, and the required force for the rehabilitation treatment is transmitted by a cable-driven mechanism. The force-delivering part can be easily attached...
This paper describes how Taurob GmbH (LLC), a startup firm in robotics from Vienna, Austria, commercialized its flagship product platform, the Taurob Tracker, using the marketing testbed (MTB) approach. Taurob developed a highly versatile robotics platform, the Tracker, for use in highly hazardous environments. The design is very modularized; it can be customized to nearly any environment, but one...
The aim of this paper is to support the idea that not only the robots behaviours, but also development/experience of the participant matters, when teaching a robot. The results presented encourage us to look more closer in the interplay between teacher and learners perspective to create the robots behaviour for a natural interaction. The results, therefore, provide both insights into individual differences...
Despite the rapid advances in technology relatively few are focused on special education, or the education for people with profound and multiple disabilities. One of the main causes for this to happen is that there is little incentive for companies to design and manufacture technology for a target group of customers without major buying power, or one that makes up a relatively small proportion of...
Computing in schools has gained momentum in the last two years resulting in GCSEs in Computing and teachers looking to up skill from Digital Literacy (ICT). For many students the subject of computer science concerns software code but writing code can be challenging, due to specific requirements on syntax and spelling with new ways of thinking required. Not only do many undergraduate students lack...
In a previous paper, we reported on the initial development of KneeRobo, which replicates knee joint troubles experienced by patients in order to enable students studying to become physical or occupational therapists to gain practical training/testing virtually. We also developed a control algorithm that enabled KneeRobo to realize involuntary internal/external rotation during knee flexion and extension...
Cognitive development is dynamic and opportunistic, following developmental pathways [1]: The same skill can develop in many different ways, depending on the chains of events and opportunities that are presented to the learning individual. What factors shape these developmental pathways?
It is impossible to determine the optimal operating conditions without any scientific substantiation for some nonlinear productions described as slow-response, nonlinear and closed. The simplified dynamic model of production which is able to evaluate the capacity of energy consumption as at static as well as at transitional conditions has been introduced. Some recommendations to solve problems of...
Our current students belong to a new generation that lives with Internet, uses computers, and plays video games as natural skills. For that generation, education based on traditional classes is difficult. In this contribution, we propose learning RADAR fundamentals by using video games. The newly designed game is described, and has been tested by a group of students. Their learning results are promising...
Aim of this paper is to present a radio communication system that can be easily integrated in an emergency communication network, which is able to relay analog and digital data. Implementation of a multiprocessor radio network controller, based on the FPGA technology, is the main goal of this project. This configuration allows a multiple possibilities of communication: APRS data transmission and analogue...
Motivated by the molecular robotics project of Japan, we investigate the problem of designing a distribution locomotion algorithm for metamorphic robotic system consisting of homogeneous modules. The algorithm, which works on each module, must navigate it so that the entire system moves in a predetermined direction. We present an algorithm that moves the system eastward, provided that an initial configuration...
