Hi, I need more info to understand the problem. Please, try to open new terminal and use the following commands: |
Thanks!It's 16.04,just continual WRN.I'm trying your solution. |
|
We used Ubuntu 18, ros melodic while writing this package. |
There are some install problems to solve before I rerun the code.Appreciate it! |
Hello, I use ubuntu16.04 and ros kinetic too. Have you run this project successfully? |
The same question to me, all the dependencies have been installed. It seems that there is no transform from base_Abot to map. Like this question https://answers.ros.org/question/280776/how-to-resolve-error-timed-out-waiting-for-transform-from-base_link-to-map-to-become-available-before-running-costmap-tf-error-cantransform/. |
Hi, please try the following installations: Could you run it once more and show me your terminal output, please? |

Hi, as you see the first pic, all the four packages had been installed before. The question still exists as the second pic.
Thank you very much.

Hi, I need more info to understand the problem.
Which ros distribution are you using?
Have you installed all the dependencies?
Can you past here all the terminal output, please?
Please, try to open new terminal and use the following commands:
sudo apt install ros-<ros_distribution>-teb-local-planner -y
python
import sklearn
import matplotlib
import scipy
import numpy
Did you had error while running any of those commands?

It seems that the MCL doesn't work properly...... |
|
Hi, sorry for the late reply. I can't see the pics you're referring to. Is it works for you? If you think there is a problem with amcl. |

Hi, it still doesn't work now. The terminal output and roswtf output are here: liurui@LR:~/mcl/src/mcl_pi_gazebo/move_base$ roslaunch mcl_pi_move_base.launch xacro: Traditional processing is deprecated. Switch to --inorder processing! SUMMARYPARAMETERS
NODES ROS_MASTER_URI=http://10.250.24.172:11311 process[gazebo-1]: started with pid [20477] And the roswtf output: (base) liurui@LR:~$ roswtf

The problem you are having is caused due to incompatibility of this repository with your ROS version. |
|
Just to clarify, this was a quick fix. |
Hello, what's the meaning of "check out ubuntu 16 branch.Download it and compile it"? |
|
Try the following commands: delete the old mcl_pi_gazebo repository: download ubuntu16 branch: compile: Check out ubuntu16 branch:
|
I run it successfully!! |

Hello sir, I successfully run your codes on ROS kinetic, and I tried to rewrite it based on a different robot model. However, after I fixed all bugs on rviz, my robots still don't move (single robot could move, but multi-robot couldn't). I checked the ros topics, and I found that lots of topics belonging to /move_base wasn't launched. The list is shown as below... [ my topics] $rostopic list [ your topics, as the comparison] $rostopic list I guess there are some mistakes in the .launch file of move_base, but I can't figure it out. |

Hi, great to know it works for you. How are you publishing the goal? Are you using rviz for that? Please check on which topic you publish the the goal. https://github.com/or-tal-robotics/mcl_pi_gazebo/tree/master/rviz https://github.com/or-tal-robotics/mcl_pi_gazebo/blob/master/launch/rviz_visualisation_mcl.launch

Much obliged for your advice, sir.
[comparison: node graph of your codes] The node of move_base is launched by these codes, and I can't find the problem...
Do you have an idea? Thank you for your reply! |
Hello,when I roslaunch mcl_pi_move_base.launch.
[ WARN] [1621153885.937166331, 20.119000000]: Timed out waiting for transform from KoBot2/base_KoBot2 to KoBot2/map to become available before running costmap, tf error: canTransform: target_frame KoBot2/map does not exist. canTransform: source_frame KoBot2/base_KoBot2 does not exist.. canTransform returned after 0.1 timeout was 0.1.

And after I set goal by rviz Nav Goal,any of robots didn't move.
Could you help me fix this issue?Thanks.
