    Reasoning and planning for mobile robots is a challenging problem, as the
    world evolves over time and thus the robot's goals may change. One
    technique to tackle this problem is goal reasoning, where the agent not
    only reasons about its actions, but also about which goals to pursue. While
    goal reasoning for single agents has been researched extensively,
    distributed, multi-agent goal reasoning comes with additional challenges,
    especially in a distributed setting.  In such a context, some form of
    coordination is necessary to allow for cooperative behavior. Previous goal
    reasoning approaches share the agent's world model with the other agents,
    which already enables basic cooperation.  However, the agent's goals, and
    thus its intentions, are typically not shared.

    In this paper, we present a method to tackle this limitation. Extending an
    existing goal reasoning framework, we propose enabling cooperative behavior
    between multiple agents through promises, where an agent may promise that
    certain facts will be true at some point in the future. Sharing these
    promises allows other agents to not only consider the current state of the
    world, but also the intentions of other agents when deciding on which goal
    to pursue next.  We describe how promises can be incorporated into the goal
    life cycle, a commonly used goal refinement mechanism. We then show how
    promises can be used when planning for a particular goal by connecting them
    to timed initial literals (TILs) from PDDL planning.  Finally, we evaluate
    our prototypical implementation in a simplified logistics scenario.
