2017 Springer Proceedings in Advanced Robotics  
The results show that these techniques improve success rate and task completion time by incorporating expected realworld performance into the system design.  ...  Household manipulation presents a challenge to robots because it requires perceiving a variety of objects, planning multi-step motions, and recovering from failure.  ...  The composition of this sequence is designed based on the overall system performance and not just the performance of the individual planners.  ...
