Abstract
We propose a flexible hierarchical navigation stack for a mobile robot in complex dynamic environments. Our solution includes several layers to efficiently decompose the complex problem into task planning, navigation, control and safe velocity components. In contrast to the prior art, our system at every level incorporates diverse contextual information about the environment, anticipates navigation risks and proactively avoids collisions with dynamic agents.
