This document outlines a roadmap for Industry 4.0 technologies. It discusses five stages of maturity: 1) conception and remote control solutions using sensors and connected devices, 2) controlled processing using techniques like laser cutting and 3D printing, 3) intelligent manufacturing using robotics and self-installing machines, 4) tasks specialization using lean manufacturing and empowering workers, and 5) emerging maturity with followers adopting precursor technologies like big data and predictive maintenance. The roadmap provides an overview of the evolution of Industry 4.0 technologies moving from remote monitoring to fully automated intelligent manufacturing.
