Distributed monitoring of heterogeneous robotic cells. A proposal for the footwear industry 4.0

Abstract

In the footwear sector, automation is often performed by robotic arms due to the inherent adaptive requirements of some of its tasks. With the Industry 4.0 revolution, automation is even less human dependent than before. The fact that fewer people interact with machinery during the manufacturing process has led to a rising need for production monitoring. The interconnection of machines present in 4.0 environments makes monitoring possible at a low investment cost. In this paper, a common communication layer is proposed to enable homogeneous status data retrieval of robotic arms from several different robot manufacturers. This layer is then attached to a 3D simulator software as a client, responsible for the monitoring process. Experiments proved the feasibility of the proposed method in a test bench scenario applying the required constraints of time, cost, bandwidth and disk space.
