# Simultaneous Use of Digital Technologies and Industrial Robots in Manufacturing Firms
## 5 Conclusions  
The main aim of our study was to provide an initial understanding of the simultaneous use of specific digital technologies and industrial robots. Our results show that the \"traditional\" types of industrial robots, such as industrial robots for manufacturing processes and industrial robots for handling processes, do correlate with the use of practically all digital technologies that are also addressed by us as Industry 4.0 enabling technologies. This finding showed a clear positive relationship when analyzing these two types of industrial robots with each selected digital technology and when the Industry 4.0 readiness concept was introduced. Additionally, the likelihood was analyzed that a certain type of industrial robot would be used when using a specific digital technology. Again, for \"traditional\" types of industrial robots, significant relationships were found that indicate the likelihood of using them with almost all the selected digital technologies. As seen, the Industry 4.0 readiness model used in our research is based on the number and combination of digital technologies used in manufacturing firms. The highest levels of Industry 4.0 readiness correlate strongly with the use of industrial robots for manufacturing processes and industrial robots for handling processes. Our results also indicate that the distribution of digital technologies in Industry 4.0 readiness levels can serve as predictors for industrial robots, such as industrial robots for manufacturing processes and industrial robots for handling processes' use. The results for the other three types of industrial robots were, in general, not significant. This can be attributed to the novelty of these types of robots since their diffusion is, in comparison to \"traditional\" types of industrial robots, rather low. According to our best knowledge, this is the first study that addresses this relationship. It was not our attempt to analyze the deeper interconnection for the simultaneous use of \begin{table}
