Item type:Publication, Access status: without files , Teleoperating mobile robots via VDA 5050 - a first middleware evaluation within open industrial networksTeleoperation is a practical fallback for mobile robots in intralogistics when rare but safety- and throughputcritical edge cases exceed autonomous capabilities. While Fleet Management Systems (FMSs) increasingly rely on vendor-neutral interfaces such as VDA 5050 to coordinate heterogeneous robots, teleoperation is not natively represented in the standard and is typically implemented as an ad hoc, robot-specific add-on. This paper closes this gap by proposing a VDA 5050 teleoperation extension that enables human-in-the-loop control as part of the same interface used for autonomous task and route coordination. To facilitate reproducible evaluation, we further contribute a configurable VDA 5050 traffic generator that reproduces realistic message patterns for middleware-based FMS communication. Employing the Open Radio Access Network (Open RAN) concept, cellular 5G and future 6G networks can be flexibly deployed in industrial environments to provide reliable, low-latency wireless connectivity for mobile robot teleoperation. Using an end-to-end stack consisting of VDA 5050 messaging, middleware transport, and Open RAN wireless link, we evaluate latency and communication overhead to characterize the performance implications of standardized teleoperation integration.Publicationtype: Conference Paper19
