2016-12-22 03:14:35 -0500 marked best answer How does global planner in teb local planner tutorial work

Previously I have ask a question about how to activate the global_plan_viapoint_sep for the tutorial, and now I encounter another problem in exploring the teb techniques, how do the global planner in the tutorial work, when I tried to go through the content in each file, it have show that the tutorial have to purpose the point and created a path related to the point, but how does this happen?

Does this planner use any global planner to generate a simple route, then using the teb local planner to optimize the route? Or it is the function of teb to generate the global path?

I have increase my resample_interval:1 to 100 in amcl_params.yaml, and It does improve my positioning problem, but the jumping problem is still happen during the simulation.

Hi everyone

I has a problem related to my simulation, I am currently running a simulation on teb_local_planner.

When I run my simulation, I found out that my robot become very slow in situation that have to go around the corner.

like this video https://www.youtube.com/watch?v=bf8ig...

here is my paste bin for the teb_local_planner_param.yaml file http://pastebin.com/7VVJ0kSL

It report warning like below

I do not think I am using slam for my package

Could you tell me how to create a map with more distinct feature. I am confuse about how to add more feature.My map are basically a .png file convert from my cad drawing I have try to set recovery_alpha_slow and recovery_alpha_fast 0.0, and unfortunately it does not work in this case.

The red arrows is the data from amcl.

Yes sure, the following url is the paste bin for my launch code, and there is a command after this comment

Hi everyone,

I have a robot positioning problem in my simulation.

In the simulation my robot will suddenly jump place near the it`s original location. Some time it will recover by itself.

And some time it just stay there, which lead to problem of collision of something even worse.

I cannot figure out which part I have done wrong.

I will put the video of my error in below, and I can provide other detail as request.

you might skip to 40second to see what happen in my rviz window

2016-08-08 00:40:28 -0500 asked a question Question about the stage tutorial -Creating Custom World in Stage

Hello,

As I follow the tutorial, I find that in the Creating Custom World in Stage http://wiki.ros.org/stage/Tutorials/C...

The tutorial stop at step 2.

And I try to implement a different size map[380x302] into the tutorial path instead of the original one. I found some errors in the simulation, the stage map look very rough, and the location of the bot in rviz and stage is different.
