Industry 4.0 enabling technologies, such as cloud data storage, autonomous robot, additive manufacturing, augmented reality, and internet of things, are increasingly being adopted by Brazilian industries. One of these technologies, the collaborative robot or cobot, has great potential for expansion, due to its application in a manufacturing environment sharing space with humans, offering a reduction in operating costs, a safer work environment, mainly for reducing risks. ergonomics and product quality gains. The general objective of this dissertation was to evaluate the economic and social gains, with a focus on the reduction of ergonomic risk and gains in quality, with the implementation of the cobot in the engine assembly process. The work presents a case study in an engine assembly company. Observation of the assembly process was carried out to carry out data collection, in addition to analysis of technical reports and interviews with managers. The method used allowed analyzing the advantages of implementing the cobot. The results indicated that the cobot integrated in the manufacturing process is advantageous for the industry. The project showed a reduction of R$208,012.80 in operating costs per year, and the return on invested capital was 1 year and 9 months. The guarantee of performing torque in the correct sequence was another important gain for product quality, in which there was a reduction in the PFMEA risk score from 196 to 56. In addition, the reduction in the ergonomic risk score from 24 to 10 provided a better work environment for the operator, avoiding possible absences. The theoretical contribution of this research was focused on offering a work not yet found in the literature on economic, social and quality advantages with the application of cobot in engine assembly process. As a contribution to corporate practice, this study aims to encourage industrial managers to seek opportunities for cobot application within the manufacturing process.
