Can't we do motion planning in 2d and 3d in Gazebo without using move_base?
if yes, how? I don't want to hard code the obstacle position I want to have a map and some obstacles in the scene and I want to just view and test the global path generated by different path planners from start to goal point. I don' want to navigate the robot. I don't want to have a robot model in the scene. Just a world with obstacles a start and goal point and the 3d global path
