Heuristic Motion Planning with Movable Obstacles

چکیده
We present a heuristic approach to geometric path planning with movable obstacles. Treating movable obstacles as mobile robots leads to path planing problems with many degrees of freedom which are intractable. Our strategy avoids this computational complexity by decoupling the whole motion planning problem into a series of tractable problems, which are solved using known path planning algorithms. The individually computed solutions are then coordinated to a path plan. This method results in a powerful and practicable strategy for path planning with movable obstacles, which can be applied using a wide variety of known motion planning algorithms.

Planning Among Movable Obstacles with Artificial Constraints
In this paper we present artificial constraints as a method for guiding heuristic search in the computationally challenging domain of motion planning among movable obstacles. The robot is permitted to manipulate unspecified obstacles in order to create space for a path. A plan is an ordered sequence of paths for robot motion and object manipulation. We show that under monotone assumptions, anti...
متن کاملAn Effective Framework for Path Planning Amidst Movable Obstacles
This paper addresses the problem of navigating an autonomous moving entity in an environment with both stationary and movable obstacles. If a movable obstacle blocks the path of the entity attempting to reach its goal configuration, the entity is allowed to alter the placement of the obstacle by manipulation (e.g. pushing or pulling), to clear its path. This paper presents a probabilistically c...

Navigation Among Movable Obstacles Mike Stilman Robots would be much more useful if they could move obstacles out of the way. Traditional motion planning searches for collision free paths from a start to a goal. However, real world search and rescue, construction, home and nursing home domains contain debris, materials clutter, doors and objects that need to be moved by the robot. Theoretically...
متن کاملPath Planning among Movable Obstacles: A Probabilistically Complete Approach
In this paper we study the problem of path planning among movable obstacles, in which a robot is allowed to move the obstacles if they block the robot’s way from a start to a goal position. We make the observation that we can decouple the computations of the robot motions and the obstacle movements, and present a probabilistically complete algorithm, something which to date has not been achieve...
متن کاملMotion planning for a robot and a movable object amidst polygonal obstacles
This paper addresses t h e m o t i o n planning problem for a robot and a movable object amidst polygonal obstacles. M o t i o n planning in this context appears as a constrained instance of t h e coordinated m o t i o n planning problem for t w o robots. Indeed, the object cannot move by itself, at only does when the robot grasps at. W e f irs t show a topological property tha t characterizes ...
