From the beginning of the 21st century on, efforts to modernize industrial automation companies took precedence, and the human factor was completely ignored by the industrial automation manufacturers in the industry and production processes. Humans were necessary only for the creation of the automated process for industrial robotics automation, performance evaluation, and management of the entire automation process of industrial robots vs service robots. This prompted the prerequisite and limitations of embedded systems and of more degree-situated people to hold the positions and that too in negligible amounts for manufacturing engineering.

In addition, customisation of mobile robot types, which is the current market trend, was not supported by the automation process. Operations under Industry 4.0 could only provide users with the established standards; deviations were not permitted. The Internet of Things (IoT), artificial intelligence (AI), robotic automation systems and robotics were just a few of the revolutionary technologies' applications.
Therefore, it is straightforward to assert that humans would continue to manage and operate the sector of robotic companies in a different manner than they did prior to 4.0. Additionally, the availability of collaborative robots for humans is the source of this distinction. The human workforce can now better manage things, ensuring the technical precision of the robots so that products can be customized. In addition, assigning heavy lifting tasks to robots that posed a high risk without compromising human intelligence or decision-making ability.
