Title:

Hybrid Conditional Planning for Robotics

Abstract:

Conditional planning enables planning for sensing actions and their possible outcomes in addition to actuation actions, and allows for addressing uncertainties due to partial observability at the time of offline planning. Therefore, the plans (called conditional plans) computed by conditional planners can be viewed as trees of (deterministic) actuation actions and (nondeterministic) sensing actions. Hybrid conditional planning extends conditional planning further by integrating low-level feasibility checks into executability conditions of actuation actions in conditional plans. We introduce a novel hybrid conditional planning algorithm that incrementally constructs a hybrid conditional plan using parallel instances of a nonmonotonic hybrid planner. We show an application of hybrid conditional planning for robotics with a service robotics scenario where a mobile manipulator sets up a kitchen table, and evaluate our parallel planner over various mobile manipulation scenarios from the perspectives of computational efficiency and plan quality.
