With the end of traditional centralized applications for production control, a new industrial era (industry 4.0) introduces computational concepts and a vision of cyberphysical ecosystems associated with intelligent factories. Using automation technologies adopts the combination of the physical and the cyber world’s, to make the technologies involved more complex and precise [48].With the search for better resource use, time, cost, and quality has been introducing by the industry, new technological challenges as work agents, instead of the traditional man labor. Which has been replaced by autonomous robotic mechanisms. Many entities choose autonomous mobile units to fulfill the dispatching tasks and the supply of material to workstations. Thus, it is necessary to have a system capable of managing all activities and behaviors adjacent to these autonomous mobile robots. The objective of this dissertation is the implementation of a management system for a fleet of mobile robots that perform logistics processes in a secure environment. The robots will move between the production and expedition areas and autonomously carry out the loading and unloading of goods between workstations. Sharing spaces and resources among themselves and with factory operators, such as stations, corridors, security doors, and elevators. The proposed model explores the scheduling of tasks to robots as their monitoring and security in all processes, from autonomous navigation to area’s transition of areas by the present security devices. The presence of several sets of sensors and devices in these units is essential to provide sensorial information about the manufacturing environment and at the same time assisting in the execution of the tasks, such as navigation, transport, loading. To extract all the functionalities, this system will also be integrated with the management and security systems of the factory, to create an overview of the current state of the shop-floor and to plan accordingly. They are integrated to provide secure communication, based on reliable protocols that ensure the veracity and communication of the entities.
