The View to the Current State of Robotics

The article deal about the development in the field of robotic research. The introduction suggests and summarizes actual development in robotics, which is heavily focused on the service and humanoid field in many applications. Next section of contribution is dealed to the development and is referred to its fundamental properties, which has current industrial robots.

Design of the Welding Fixture for the Robotic Stations for Spot Welding Based on the Modular Concept

Design of the Welding Fixture for the Robotic Stations for Spot Welding Based on the Modular Concept The article describes the methodological approach to design of welding fixtures for robotic cells based on principles of modularity. In further states the basic preparation components, their functions and possible board types in terms of shape and dimensional characteristics. The proposed methodology was tested for robotic training workstation with robot KUKA for spot welding of car bodies.

Design of Modular Gripper for Industrial Robot

The article discusses the design of modular gripper for industrial robot based on the modularity. This modularity includes the variable layout of fingers into three positions for the specified grip. It also consists of the specification of objects manipulation, their dimensions and weights with this type of gripper. The proposal is based on the biomechanical principle of the human hand. According to the analysis of human hand, there is a possibility to categorize every type of grip. The concept of gripper will introduce its own possibilities, functionality and fulfillment of required grip tasks. Design is based also on limited requirements, which are determined by the envelope of flange of industrial robot, application and others factors.

Transferring image processing algorithms on application with multi arm robot and mobile phone

This article deals with application that serves for controlling of movements for multi arm robot with possibility to sent its communication on mobile phone. Resultant application was created with the help of equipments: dual arm robot, camera, computer and mobile phone or tablet with accelerometers sensor and bluetooth interface. During the phase of realization was necessary to create four software applications: software for robot movements in robot control system, software for OS android, software for communication in computer and finally software for image processing in computer. At article is mainly described part of program for image processing where we wanted to test transmission of adapted algorithms from robotic soccer (MiroSot category). Last part contains obtained pictures from software for image processing with real results.

Design and Implementation of Remote Lab with Industrial Robot Accessible through the Web

This paper describes design and implementation of remote lab with industrial robot accessible through the web based on Moodle portal, Easy Java Simulations (EJS) and Arduino Sw & Hw. The main purpose of this lab is to improve study, training and programming knowledge in industrial and service robotics for students, teachers of secondary vocational schools and company workers that deal with problems that arise on real robotic workplaces. This lab allows the user to work from their homes and operates with industrial robot at real workplace. Such remote lab can also enable users to use expensive lab equipment, which is not usually available to all persons. Practical example of application of the lab with industrial robot on Department of Robotics, Technical University of Kosice, Slovakia is presented.

Methodology for the vibration measurement and evaluation on the industrial robot Kuka

The aim of this paper is to point out the need of applying the proactive and predictive maintenance as the key instrument for the maximum operational reliability and usability of the industrial robots using the minimum costs and human resources. We want to emphasize that by the vibrodiagnostics method, which is one of the methods for ensuring the operability of the robot, extended life of the industrial robots and energy savings will be reached. The vibration measurements had been realized using the three accelerometers. Their evaluation was done via computer software ScopeWin. FFT transformation was applied for analysis of the spectrum of vibration. The purpose of the paper lies in proposing a comprehensive methodology for the measurement and evaluation of vibration on the industrial robot, and serves as a way to obtain additional recommendations and drafts of the procedures for maintenance and fault diagnosis of the industrial robots.

Assisted Research of the Centrifugal Pump's Vibration Behavior

Vibration sources and types of defects that can be analyzed for equipment or working machine are numerous and depend on the type, mode and operating conditions, mechanical structure, such shareholders. In this paper, to determine the operating status and level of vibration (machinery due to mechanical faults) , the method uses FFT (Fast Fourier Transform method), to Online simulation of the defect it uses the method virtual world, LabVIEW

Modular Welding Fixtures for Robotic Cells

This paper describes the proposal of welding fixtures which achieves pre-arrangement of individual parts of fixture based on suitable modules. Also is focused on methodological process of their design using modularity principle and reconfigurability. Describe procedure of designing fixture with emphasis to specific requirements for welding fixtures in robotic welding. Take advantages of simple substitution of individual modules welding fixtures by database compatible with modules in 3D environment. Optimization and control of collision status is realized in simulation environment ABB Robot Studio.

Principles of Formation of Flexible Manufacturing Systems

The article presents points necessary for the production re-prophilation into the flexible one through the generation of so called flexible manufacturing cells. Mentioned are the reasons and effects which are brought by the flexible production. In general, the key to the generation of the flexible production is the group technology based on the principle of the material flow analysis. The variants of the possible solutions based on the material flows confirm that the problem of the flexible manufacturing cells generation is not an easy one and unambiguous either. But considering only this one criterion is not sufficient for the practice because it does not consider for example the number of the pieces. Therefore the present article in the principle points at the application of the multiplied criteria about the part or machine, based on which more specifically stated is the cell profile, as number of machines, type of machines, intercellular transfers and so on.

Needs, Opportunities and Constraints on the Way to the Wide Introduction of Robotics to Teaching at Secondary Vocational Schools

The current situation of increasing European and global competition and the resulting downward pressure on prices and forcing at companies use modern automated and robotic manufacturing systems. After the state of the art analysis evaluation there were certain conclusions gained, showing lack of information from the field of robotics among graduates. Low level of education in the field of robotics is caused by poor material and technical facilities at secondary schools as well as by poor level of theoretical and practical experiences of teaching staff. Therefore, the staffs are not able to pass on important and satisfactory level of education in the field of robotics. This clearly demonstrates the need and necessity of education in the field of robotics that can be adequately insured by professionally trained teachers. Teachers will benefit in terms of gaining the latest information and knowledge from the field of industrial and service robotics, which is now highly popular and attractive giving them the benefit of professionalism. The paper presents the works within the RUSOS project, which is focused on educating of teachers of secondary vocational schools in the field of robotics.
