Based on the experiences from an autonomous mobile robot project called MOBOT-III, we found hard realtime-constraints for the operating-system-design. ALBATROSS is "A flexible multi-tasking and realtime network-operating-system-kernel". The focus in this article is on a communication-scheme fulfilling the previous demanded assurances. The central chapters discuss the shared buffer management and the way to design the communication architecture. Some further aspects beside the strict realtime-requirements like the possibilities to control and watch a running system, are mentioned.
