Autonomous Mobile Robots with Business Process Management Systems at the Edge

Abstract

Business process management systems (BPMS) are widely used key components in software architectures of purely digital enterprise applications to organize, execute, and analyze business processes. More recently, BPMS have gained attention from the Internet of Things (IoT) and Cyber-Physical Systems (CPS) communities to be leveraged for automation and orchestration of sensors, actuators and more complex devices controlled by software. We present an experience report of using executable business processes and BPMS to orchestrate autonomous mobile robots. The focus of our investigations is on using robots as edge devices acting as local execution platforms for BPMS. We benchmark the impact of a common BPMS on the robot’s resources during autonomous navigation and compare with traditional client-server deployments. The experimental results with real robots controlled by a Raspberry Pi demonstrate the feasibility of using common, standardcompatible BPMS in edge computing scenarios to orchestrate CPS.
