Abstract

In order to pick (place) a target object from (on) a shelf, a service robot moves to the front side of the shelf, removes obstacles, and reaches out a hand. If the robot prepares for the next arm manipulation while moving to the shelf, it is possible to save time for plan execution. The robot also needs to replan if, for example, a person removes obstacles for the robot. After replanning, the robot might need to suspend the current action execution or next action preparation before executing the updated plan. This paper introduces a method to integrate planning, action execution, speculative next action preparation, replanning, and action suspension based on Hierarchical Task Network (HTN) planning. We also show that this method is effective for pick-andplace manipulation in dynamic environments.
