The1980sand1990ssawincrementaladvancementsin robotic control systems and sensor integration, enabling basic forms of environmental awareness and limited flexibility(Huangetal.,1999).However,trueintelligence understood as the ability to perceive, reason, and learn remainedoutsidethescopeofconventionalindustrialrobots. At the same time, research in AI was gaining momentum, especiallyinmachinelearningandexpertsystems,layingthe groundworkformoreintelligentautomation.
The early 2000s marked a turning point with the convergence of AI algorithms and robotic platforms. Developments in computer vision, probabilistic reasoning, and sensor fusion allowed robots to interpret visual and spatial data in real time (Thrun, 2002).

As a result, manufacturingsystemsbeganevolvingintosmartfactories characterized by autonomy, connectivity, and continuous optimization hallmarks of the Industry 4.0 paradigm (Kagermannetal.,2013).
Today, cognitive robotics continues to evolve with the integration of edge computing, cloud robotics, and cyberphysical systems, bringing real-time AI processing and decentralizedintelligencetomanufacturingfloors(Zhouet al., 2020). These systems not only improve efficiency and product quality but also facilitate rapid reconfiguration, predictivediagnostics,andhuman-robotcollaborationatan unprecedentedlevel.
