"The dwa local planner failed to find a valid plan, cost functions discarded all candidates. Okay, try one more thing (that I really should have mentioned the It outputs "The dwa local planner failed to find a valid plan, cost functions discarded all candidates. The DWA_local_planner works well but I'm facing an issue when I put an obstacle in its way (the obstacle is put in its global path before it starts to move). Dear David, Please test-compile your code before making other people try it. The problem is from global planning. With a value of 2 seconds it It's still sending forward command to my driver. After a while, the systems starts the recovery actions but the next message prompts in the console: @breeze Please open up a separate question.

Looking at the code (dwa_planner_ros.cpp) that produces this message it looks like it is being produced because a 0 or negative cost path is being produced. Higher values for the cheat_factor don't and keep moving forward. As I am a remote worker, I've not had an "expert" looking over my shoulder although I am very active on boards to ask questions. Can you try this branch please? min_rot_vel: 0.02 After I set the xy_goal_tolerance larger then the problem fixed. The dwa_local_planner package provides a controller that drives a mobile base in the plane. Other threads suggested to use default parameters and then tune every single parameter in order so see which parameter causes the problem, but when using only default-params the issue remained, too.

And the bot doesn't move. A setup like this used to work for me, and a near-identical configuration of simulation and navigation is working fine for colleagues in the same team running Ubuntu 12.04. Scientists researching magnetic confinement fusion aim to use stellarator devices as a vessel for nuclear fusion reactions. Please start posting anonymously - your entry will be published after you log in or create a new account. During the last rotating stage, the orientation haven't been reached, so latching is reset. Seriously though, try it again after you pull the latest version. If it's the reason, you can just make your robot stop if not receiving anything. I am running hydro on OS X installed using Homebrew, but with the navigation stack updated to the latest version (* hydro-devel 8824c44 fix robot_pose_ekf test) from its GitHub (and a few other packages updated too). I have checked the cmd from dwa. . This can mean there is an obstacle too close to the robot." local_plan. In RViz the local and global cost maps are clear. A stellarator is a plasma device that relies primarily on external magnets to confine a plasma. @RalphKai Maybe your robot has not received a 0 cmd?

If it's a regular topic @hawesie Which branch/distro of navigation are you using? However it's pretty complicated to set up. Hi everybody, currently, I'm working on AMCL navigation (from Point A to Point B) and for this reason I'm using DWAL_local_planner. :-). Where does it come from? If the fix can read it here: ReadMehttp://rchh.org:81/software/otter4_documentation/tree/master. the parameter yaml of move_base show as follow: DWAPlannerROS: # Robot Configuration Parameters - Kobuki max_vel_x: 0.1 # 0.55 min_vel_x: 0.0 max_vel_y: 0.0 # diff drive robot min_vel_y: 0.0 # diff drive robot . When reaching the goal, topic cmd_vel stops publishing, but the last cmd your robot received is not 0, so it keeps going. DWA planner always fails for me in simulation. Oh dear, I hope it's not completely my fault in the end having busted your whole weekend for nothing would be a pretty unpleasant thought. report back.

On Fri, Dec 6, 2013 at 1:28 PM, Hendrik Wiese [email protected]: Yeah, that's what I thought. And it still happens. You signed in with another tab or window. This can mean there is an obstacle too close to the robot. We don't want the robot being latched if we get a new goal, so when there is a new global plan, move_base will reset Latching. At the moment I'm using the following params: Note that the occupancy grid which is used as map_topic gets updated/published every 5 seconds. I couldn't find it anywhere, neither something that looks at least similar. To make sure it wasn't a DWA planner parameter tuning issue, I used it with turtlebot3_navigation params (like @Rayman's turtlebot3_mbf pkg) with launch file like in ceres-navigation first time): Same branch but set DWAPlannerROS/scaled_path_factor to 0.75. offline? Alright, phew, that takes a load off my mind. $MOVE_BASE_NAMESPACE/DWAPlannerROS/cheat_factor 2. Or should it work out of the box? Does this happen under Ubuntu 14.04 and ROS Indigo? Higher values for the cheat_factor don't appear to have bigger impact on this behavior. Hi, I had a similar problem without using a global planner on a differential wheeled robot.

Can you add TF and the goals to DWA planner always fails for me in simulation. . Were you recording the trajectory cloud as well when you made this bag? On Tue, Dec 17, 2013 at 3:00 PM, Hendrik Wiese [email protected]: I think, I recorded everything. Make sure that it is The fundamental problem stems from the weight on the alignment cost being set incorrectly (see 6a72c61 for one fix). If the fix hasn't yet been merged into it, I don't use it. Yeah, that's what I thought. https://github.com/ros-planning/navigation/blob/hydro-devel/dwa_local_planner/src/dwa_planner.cpp#L176 I'll continue watching it tomorrow (well, today, At first sight, it looks like you don't have the libraries installed.

I want to check in my python code if DWA local planner failed, and if so, I . I will come back to this at the weekend and see if I have any further inspiration. I am using gmapping to make the map. Ok. As implied by the name, cheat_factor isn't a real fix. There is another quick dirty way, just set planner_frequency in move_base params to zero, then global planner will only work when we get a new goal or local planner fails, so latching won't be reset too often. changes it at least worked with a low sim_time and a for my setup if you have time. Because my robot is carlike robot, so it have some limitation to move exactly the goal's pose.
