Advances in individual robotic fields such as Simultaneous Localization and Mapping, large-scale and local trajectory planning, sensor data processing and mechatronics have allowed mobile robots to operate in more complex environments. However, these fields are usually investigated independently, resulting in a lack of cross-layer integration and synchronization that affect safety due to incompatible timing constraints and error handling of different components. In this paper, we propose an integrated contract-based robot navigation stack from sensors and actuators to abstract intelligence. This stack is resource-and safety-aware. It allows continuous operation of a mobile robot within a complex environment.
