We consider the setting where a robot must complete a sequence of tasks in a persistent large-scale environment, given one at a time. Existing task planners often operate myopically, focusing solely on immediate goals without considering the impact of current actions on future tasks. Anticipatory pl
We address the task of long-horizon navigation in partially mapped environments for which active gathering of information about faraway unseen space is essential for good behavior. We present a novel planning strategy that, at training time, affords tractable computation of the value of information…
We improve reliable, long-horizon, goal-directed navigation in partially-mapped environments by using nonlocally available information to predict the goodness of temporally-extended actions that enter unseen space. Making predictions about where to navigate in general requires nonlocal information:…
