Abstract:or map the set of feasible motions onto a network of In this paper, a hierarchical A* -based method for motion planning of robot manipulators is presented. The algorithm's advantage is its simplicity. The algorithm is also shown to be resolution complete.The algorithm searches the robot's configuration space with many different "step sizes" at the same time. The step size denotes the distance between the nodes A' expands during the search. When a path candidate goes far from the obstacles, a big step size is u… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
