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? |

2016-09-15 21:27:15 -0500 | commented answer | Robot location jump in RVIZ window 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. |
2016-09-15 21:23:43 -0500 | asked a question | Virtual robot speed reduce when approaching to corner 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 |

2016-09-15 20:46:24 -0500 | commented answer | Robot location jump in RVIZ window 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. |

2016-09-13 03:01:11 -0500 | asked a question | Robot location jump in RVIZ window 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. https://www.youtube.com/watch?v=zq32Q... 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. |
