Abstract: The goals of the interdisciplinary project HORN were as well to improve competitiveness of service providers that deliver grocery items as to develop new hardware and software needed for its realisation. In the first part, we introduce this home replenishment project, and analyse the needs and challenges of mobile services with similar constraints. In the second part, we introduce our modular software engineering approach and especially present the adopted reconfiguration mechanism for autonomous mobile applications, and its profiling concept.
