Many planners in OMPL (including the default one) favor speed of finding a solution path over path quality. Learn more. Before setting the first planning goal, make sure to set a pose estimate outside of the map edges, otherwise planning will fail (map edges are treated as obstacles by the planner). C++ implementation for State Lattice Planner. The planner is designed to plan time dependent, dynamically feasible navigation paths for robots with differential drive constraints. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. More software details can be found here.
