SUMMARYLearning in the age of information superhighway necessitates a properly-developed efficient vehicle that is not only powerful in directing users to the needed information or to situate in a reality through virtual settings, but also controllable at the various comfortable paces. The goal of this project is to explore a new on-line medium for users to navigate at their own pace in the structured cyberspace—knowledge space composed of concepts, systems design, application-oriented case studies, up-to-date industrial news (trends and product review), and on-line robotic systems, and to use it as a robotics work-bench for conducting controllable experiments/simulations. Through such an electronic learning medium, users will be able to acquire a global outlook as well as an integrated understanding of modern robotics in a manner that is low-cost, time-and-place-free, and student-centered.

The Information SuperHighway, Email, The Internet, FTP, BBS, Modems, : all buzz words which are becoming more and more routine in our daily life. Confusing terminology? Hopefully it won't be in a few minutes, all you need is to have a handle on a few basic concepts and terms and you will be on-line with the rest of the "telecommunication experts". These terms all refer to some type or aspect of tools associated with a range of computer-based communication software and hardware. They are in fact far less complex than the instruments we use on a day to day basis as microscopist's and microanalyst's. The key is for each of us to know what each is and how to make use of the wealth of information which they can make available to us for the asking. Basically all of these items relate to mechanisms and protocols by which we as scientists can easily exchange information rapidly and efficiently to colleagues in the office down the hall, or half-way around the world using computers and various communications media. The purpose of this tutorial/paper is to outline and demonstrate the basic ideas of some of the major information systems available to all of us today. For the sake of simplicity we will break this presentation down into two distinct (but as we shall see later connected) areas: telecommunications over conventional phone lines, and telecommunications by computer networks. Live tutorial/demonstrations of both procedures will be presented in the Computer Workshop/Software Exchange during the course of the meeting.

AbstractIn the present work, a novel continuous flow system (CFS) is developed for the preconcentration and determination of Cr (VI) using Pseudomonas aeruginosa static biomass immobilized onto an effective and low-cost solid support of powdered eggshells. A mini glass column packed with the immobilized biosorbent is incorporated in a CFS for the preconcentration and determination of Cr (VI) from aqueous solutions. The method is based on preconcentration, washing and elution steps followed by colorimetric detection with 1,5-diphenyl carbazide in sulphuric acid. The effects of several variables such as pH, retention time, flow rate, eluent concentration and loaded volume are studied. Under optimal conditions, the CFS method has a linear range between 10 and 100 μg L-1 and a detection limit of 6.25 μg L-1 for the determination of Cr (VI). The sampling frequency is 10 samples per hour with a preconcentration time of 5 mins. Furthermore, after washing with a 0.1 M buffer (pH 3.0), the activity of the biosorbent is regenerated and remained comparable for more than 200 cycles. Scanning electron microscopy reveals a successful immobilization of biomass on eggshells powder and precipitation of Cr (VI) on the bacterial cell surface. The proposed method proves highly sensitive and could be suitable for the determination of Cr (VI) at an ultra-trace level.

Out Of Plane

Future robotic systems will be pervasive technologies operating autonomously in unknown spaces that are shared with humans. Such complex interactions make it compulsory for them to be lightweight, soft, and efficient in a way to guarantee safety, robustness, and long-term operation. Such a set of qualities can be achieved using soft multipurpose systems that combine, integrate, and commute between conventional electromechanical and fluidic drives, as well as harvest energy during inactive actuation phases for increased energy efficiency. Here, we present an electrostatic actuator made of thin films and liquid dielectrics combined with rigid polymeric stiffening elements to form a circular electrostatic bellow muscle (EBM) unit capable of out-of-plane contraction. These units are easy to manufacture and can be arranged in arrays and stacks, which can be used as a contractile artificial muscle, as a pump for fluid-driven soft robots, or as an energy harvester. As an artificial muscle, EBMs of 20 to 40 millimeters in diameter can exert forces of up to 6 newtons, lift loads over a hundred times their own weight, and reach contractions of over 40% with strain rates over 1200% per second, with a bandwidth over 10 hertz. As a pump driver, these EBMs produce flow rates of up to 0.63 liters per minute and maximum pressure head of 6 kilopascals, whereas as generator, they reach a conversion efficiency close to 20%. The compact shape, low cost, simple assembling procedure, high reliability, and large contractions make the EBM a promising technology for high-performance robotic systems.

Abstract Project-Based Learning (PBL) is an active student-centered learning methodology. Several schools (of varying degrees of education) have implemented, in different ways, PBL, having as common strands that the student learns in teams, and being challenged in the context of a case-scenario. In Portugal, a PBL methodology has been implemented, in the first year of an Industrial Engineering and Management (IEM) program, for more than 15 years. This represents a total number above 700 students of IEM enrolled in PBL during the reported timeframe. A continuous improvement process of the PBL activities was relentlessly pursued during such period. Grounded on end-of-term on-line PBL process satisfaction questionnaires, as well as on results of each PBL edition final workshops, this paper studies and reports on a number of such achievements and shortcomings. Thus, this paper presents the analysis of the results of ten academic years of PBL evaluation process, grounded on the compiled results obtained from 2009/10 to 2019/20. Also, a synthesis of the effective findings (either positive or negative), systematically pointed out by the students, will be presented. Altogether, the PBL implementation in the IEM program has been very positive for students and teachers and worth for others to follow.

This year we celebrate the 70-th year of the chair founded in BMSTU in 1951 which name today is "Robotic Systems and Mechatronics". Evolution of the chair during the last 70 years is completely reflected the technical progress in the field of automation. From automatic drives to autonomous robots. Again with the improvement of the educational programs in accordance with the vital demands the chair managed to keep the basic traditions of the Russian engineering school based on the combination of the fundamental scientific background with the practical competence in the new technical systems design. The prominent scientists and engineers made a major contribution to the content and methods of training of future specialists in robotics and mechatronics which are acknowledged both in Russia and abroad. Nowadays robotics is transforming from perspective direction to urgent needs. The chair "Robotic Systems and Mechatronics" is completely ready to reply the new challenge of time.

Video processing technology is regarded as a low-cost detection technology in complex environment. Because the placement layer is thin and the surface is complex that causes high detection error and high cost in laser measurement. Two problems must be solved before using it in large-scale composite structures automatic placement. One is to obtain the high-quality and stable image, and the other is to improve efficiency of image processing. In this paper, a method obtaining the high quality placement gap images was studied. It made use of the optical characteristics of composite material’s surface texture. And some parameters were determined by experiments. To reduce the calculation cost of image processing, a placement gap measurement method based on line scanning was also proposed here. The method was effective in our detection experiments on an actual workpiece.
