2019-12-17 11:03:19 -0500 | marked best answer | Move base navigation malfunctions Hi all, I am developing a diff wheel autonomous robot using the move_base package. I use wheel encoders, a lidar sensor and AMCL to estimate the current pose. When I set a simple goal, 1 meter to the right of the initial pose which I manually set, the global plan of NavfnRos seems fine. However the local plan deviates from this plan, which causes the robot not to get to its goal. See the screenshot below.
You see the upper green line is the path as retrieved from topic /move_base/TrajectoryPlannerROS/local_plan. My question is: why does the local plan diverge from the global plan? It would make a lot more sense if the local plan would turn right instead of left. EDIT Here is an RVIZ capture video where you see the behaviour of the local path: https://www.youtube.com/watch?v=oYihWi8htt0 Thanks in advance, Simon |
