Member Function Documentation

◆ computePlacePlan()

def computePlacePlan (   self,
StatePuzzleScene  scene,
ImageRGBD  rgbd 
)
@brief  Computes a custom place plan. Starts by filling in pieces from 
        most populated zones to least populated zones.

◆ getNextAction()

def getNextAction (   self,
ImageRGBD  rgbd = None,
StatePuzzleScene  scene = None 
)
@brief  Return the next action to execute from current solver state.

Args:
    rgbd: Optional RGBD image for the current scene.
    scene: Optional current scene state.

Returns:
    Action

◆ getSortPlan()

def getSortPlan (   self,
ImageRGBD  rgbd = None,
StatePuzzleScene  scene = None 
)
@brief  Return the sort plan with correct piece ordering for robot
        to execute. Based on the policy set initially

Args:
    rgbd: Image details
    scene: Segmented scene information
