Abstract

This bachelor thesis deals with the replacement of human labor by industrial robots, with a focus on improving ergonomics in serial production environments. The aim of the work is to analyze and compare two selected workstations that have been robotized, and to evaluate the impact of automation on operator workload, process efficiency, manipulation quality, and operational reliability. The analysis focuses on the RESH 2 workstation, where the manual packaging of finished products has been fully replaced by an automated system using two ABB robots, and on the MK100 station, where a collaborative UR robot was introduced for inserting and removing rotors in a winding machine. For both stations, a technical description, time cycle analysis, ergonomic assessment of manual tasks, and a comparison of the pre-and post-automation state were carried out. The results show that robotization significantly reduced both the physical and cognitive workload of operators, improved process stability, minimized handling errors, and led to better production organization. The thesis also evaluates the operational benefits, failure rates, and return on investment, with both analyzed cases showing clear positive effects on ergonomics and productivity.
