Robotic technologies are becoming popular and almost essential nowadays in many industrial sectors and for the most disparate purposes. They provide huge benefits to companies and workers: carry out monotonous, unpredictable, and hazardous jobs in harsh environments, resulting in an increased safety and availability of personnel that can be differently deployed. Plant inspection and maintenance are generally human-intensive. Tedious and repetitive tasks may entail decreasing attention spans of employees, leading to errors that may have serious consequences. In that context, robots accomplish thoroughness, safeness, cost and time efficiencies. This thesis work is part of the project carried out by Sprint Reply from the group Reply S.P.A., a company hard-experienced with Robotic Process Automation, OCR tools, Natural Language Processing as well as physical social robots.
