Revision history [back]

Ivan,

Are you using OMPL directly? The start trees cannot be initialized by a planner when there are no valid starting states. Is your start state in collision? Or at a state that does not satisfy the state validity constraints? If you are using ROS, make sure you turn on DEBUG and see if you get more information.
