Unified edge control for mobile robots based on VDA5050 and basys 4.0 - Architecture and interfaces
Abstract
Following the Industry 4.0 paradigm, flexible manufacturing systems are now researched and implemented to allow fast reaction on changing market conditions. The trend leads to the development of low volume and high mixture production. Here, automated guided vehicles (AGV) and autonomous mobile robots (AMR) interconnect machine tools and automated assembly stations. Current integration of mobile robots in industrial manufacturing processes often rely on single solutions by various equipment suppliers that are not compatible with each other. Extending the factory's intra-logistics with additional AGV applications results to raising number of control systems with specific MES-interfaces. To combine different mobile robots into a managed fleet with common master control is difficult and needs a lot of implementation effort. This work contributes with a proposed Unified Control System for Mobile Robots on three layers allowing direct control of robot tasks, single robots or even particular on-board components. The proposed unified interfaces extend the VDA5050 as a common specification towards a fully open mobile robot control system using ROS together with an AAS-based automation middleware BaSys 4.0. The experiments show the feasibility of such distributed control system for mobile robots even in unknown and unstructured environments. Three case studies were carried out to assess the installation time of mobile robots in new applications. This installation time is reduced to 30 minutes including mapping, definition of points-of-interest (POI) as well as first mission design.
