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.

Multiagents System with Dynamic Box Change for MiroSot

In multiple robotic system, from the point of view of control, there are crucial knowledge of the vision of the states on the playground, communication and cooperative. Our article describes a further significant factor of multirobotic system, and namely a dynamic exchange of strategic positions and actions of robots. In real football, if a player whose dominant role in a team is defence, but if there arises a suitable situation for the attack, he carries out this action but in the same moment another his team-mate takes up the function of a defender in case he receives a ball and an opponent starts to attack. The article defines a set of actions for the robot within the strategy. In the article, dynamic change of agents means that the software agents exchange control of robots, what means that there occurs a commutative substitution of identity. This approach is described in two basic actions of SjF TUKE Robotics team.

Procedure Selection Bearing Reducer TwinSpin for Robotic Arm

The current mechanical engineering applications require the use of increasingly larger share precision reducers and special mechatronics units with a high degree of integration. High precision gearboxes is used for such applications with low backlash and high torsional stiffness (harmonic, cycloidal or planetary). Bearing reducers (cycloidal gear) meet the requirements of small built-in space in the implementation a high-precision change of transfers. Bearing reducers TwinSpin from company Spinea accurately fulfil all of these conflicting requirements.

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.

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.

Testing of parameters of proposed robotic wrist based on the precision modules

The use of precision actuators in robotic arm comes from the need to ensure the resulting accuracy of the robot at the maximum speed of movement. The replacement of actuators by means of electrical module allows the use of carrier body of the module for gripping flanges or other modules. Development of new modules is based on the requirement of providing a complete solution for the customer’s needs. After the development of new modules, the producer checks the parameters, receives feedback, and uses the authentication options in the independent workplaces, which can provide impartial results. Based on this data, manufacturers can optimize their solutions and deliver the products to market, complying with not only their vision but mainly the needs of customers. This article describes how to verify the characteristics of the modules used in the construction of robotic wrist. It primarily focuses on verification of the accuracy of results and repeatability of position of the wrist on output flange end module. In addition, it presents the design of the testing stand and selection methodologies of measurement. The declared values are compared with the values measured during verification.

Proposal of Multi Robotic Cells for Production Lines

The paper is focused on the determination of the number of robots for multi robotic cells that can be part of the line, respectively as an individual, for example sub-assemblies welding of car bodies. This paper describes general process steps of the methodology of design of multi robotic systems with a more detailed description of the determination of number of robots in the workplace. Some methodological steps are illustrated by specific examples.

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.

Possibilities of Use of Virtual Reality in the Field of Manufacturing Systems

The paper presents the structure and performance of the system created by a work team at Department of Production Systems and Robotics at Technical University of Kosice. System MSEVR – „ Modular system for experimentation in virtual reality“ is universal flexible system created for teaching automated and robotic systems by means of new advanced teaching aids, including virtual reality. It has been created as a specialized website and its possibilities are varied. Particular use depends on creativity of a user. Built-in tools enable to use it adequately when teaching construction of industrial robots, to present their kinematic structure or other properties of individual machines. It also enables to work with machine aggregate. In real-life working the system has been tested for optimization of process layout where the full advantages of virtual reality were taken.
