Automated and Robotized Systems

Abstract Automated and robotized systems are widely used in industry with deployment to perform unsafe, hazardous, highly repetitive and unpleasant tasks for human. Furthermore, industrial robot, unlike human, can perform complex or mundane tasks without tiring, and they can work in hazardous conditions that would pose risks to humans. For example, robots are increasingly being used in industry to perform such tasks as material handling and welding, and there are around one million robots in use worldwide. However, robots can pose hazardous risks to humans if sufficient precautions are not provided. To avoid injury, it is necessary to find a mutual link between the behavior of the robot and possible personal injury. It is usually necessary to ensure that the robot has not exceeded the maximum safe zone, and thus it has not come into contact with man. Safe planning is an important component of the safety strategy. Safety planning and the a priori identification of potentially hazardous situations as a means of reducing potential robot-safety hazards have received less attention than control-based (reactive) techniques. So, it is necessary to manage of risk for humans working near robots involves in general very broad considerations, ranging from potential electrical and pressurized fluid hazards, pinching hands, dropping parts, etc

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

Testing of adhesive spray painting with robot

Cilj je ovoga rada određivanje odgovarajućih parametara za raspršivanje adheziva korištenih u industriji uz primjenu robota. Korišten je robot ABB IRB 1600 u neeksplozivnom okruženju. Adheziv se oslobađao iz tlačne posude i nanosio raspršivačem Krautzberger RA5. U radu se daje detaljan opis dijagrama za automatsko spajanje pištolja za bojenje. Rezultati pojedinačnih testova dani su u tablicama, a ovisnosti pojedinih parametara prikazane su u grafikonima. Ovisno o količini nanesenog mlaza, najbolji uzorci su ocijenjeni u skladu s preporukama proizvođača adheziva.This article aims at setting appropriate parameters for robotic spraying of adhesives used in industry. The robot ABB IRB 1600 was used in a non-explosive environment. The adhesive was dispensed from pressure sweat and applied by a Krautzberger RA5 spray head. The article describes a detailed diagram for automatic connection of a painting gun. The results of the individual tests are shown in the tables and the dependencies of the individual parameters are described in the graphs. Depending on the amount of spray applied, the best samples are evaluated according to the adhesive manufacturer\u27s recommendations

LABORATORY OF INDUSTRIAL ROBOTICS AS SOURCE FOR OBTAINING OF PRACTICE KNOWLEDGES FROM CONTROLLING AND PROGRAMMING OF ROBOTS

The laboratory of industrial robotics aspires to deliver learning opportunities in Science, Technology, Engineering and Mathematics to communities where exposure is limited. The laboratory provides students with the resources to explore the fields of robotics in conjunction with high quality instruction and guidance from industry mentors. This laboratory is characterized by the need of robotics knowledges into traditional secondary vocational schools, which should provide the basic as well as advanced experiences, to address the needs of students, teachers and employees at different education levels. In this paper, we present the development of main workplaces for support virtual Moodle courses, as well as the training and relevant research

Center of Gravity Coordinates Estimation Based on an Overall Brightness Average Determined from the 3D Vision System

In advanced manufacturing technologies (including complex automated processes) and their branches of industry, perception and evaluation of the object parameters are the most critical factors. Many production machines and workplaces are currently equipped as standard with high-quality special sensing devices based on vision systems to detect these parameters. This article focuses on designing a reachable and fully functional vision system based on two standard CCD cameras usage, while the emphasis is on the RS 232C communication interface between two sites (vision and robotic systems). To this, we combine principles of the 1D photogrammetric calibration method from two known points at a stable point field and the available packages inside the processing unit of the vision system (as filtering, enhancing and extracting edges, weak and robust smoothing, etc.). A correlation factor at camera system (for reliable recognition of the sensed object) was set from 84 to 100%. Then, the pilot communication between both systems was proposed and then tested through CREAD/CWRITE commands according to protocol 3964R (used for the data transfer). Moreover, the system was proven by successful transition of the data into the robotic system. Since research gaps in this field still exist and many vision systems are based on PC processing or intelligent cameras, our potential research topic tries to provide the price–performance ratio solution for those who cannot regularly invest in the newest vision technology; however, they could still do so to stay competitive

A Non-Anthropomorphic Bipedal Walking Robot with a Vertically Stabilized Base

The paper deals with the proposed concept of a biped robot with vertical stabilization of the robot’s base and minimization of its sideways oscillations. This robot uses 6 actuators, which gives good preconditions for energy balance compared to purely articulated bipedal robots. In addition, the used linear actuator is self-locking, so no additional energy is required for braking or to keep it in a stable position. The direct and inverse kinematics problems are solved by means of a kinematic model of the robot. Furthermore, the task is aided by a solution for locomotion on an inclined plane. Special attention is focused on the position of the robot’s center of gravity and its stability in motion. The results of the simulation confirm that the proposed concept meets all expectations. This robot can be used as a mechatronic assistant or as a carrier for handling extensions
