did you solve this problem , i did the same steps you mentioned i have the same error , i don't know why , any help ? |
|
@ayahelmyy Hey! Please share the complete log, and I will try to help you. Please also tell us what ROS distro you have. Do you have a hardware controller flashed with the correct firmware and running? |
|
i'm using foxy distro , i tries the hoverboard with ros1 , and there was no problem with the firmware , but i don't know why it gave this error here is the output "[INFO] [launch]: All log files can be found below /home/aya/.ros/log/2025-02-06-14-39-25-420191-aya-IdeaPad-Gaming-3-15IMH05-125194 |
|
i only download your repo from the branch foxy , and download the https://github.com/hoverboard-robotics/ |
|
|
|
the workspace include these files |
|
Just to be sure :) Have you switched to the foxy branch? |
|
yes |
|
i replied to this issue because i made the same things he did , and have the same errors from the foxy branch |
|
@ayahelmyy Sure, let me reproduce the problem. I have to prepare a containerized workspace with the foxy distro and try to run the code from scratch. |
|
okay , please let me know the problem if you solve this , it will be very appreciated to reply on me back later , because i need to urgently and i didn't find any package for foxy , all is humble only |
|
@ayahelmyy, I have added a simple fix to the foxy branch. Please pull the changes and check. The first problem should be solved :) I have a lookup error in my containerized environment, but please check if it will also appear in your environment. |
|
okay i will check it now , and tell you |
|
did you try it and no errors found? because same errors found |
|
|
|
@ayahelmyy Yes, the problem should be gone. I don't have this error anymore. You have to download the changes, compile the code (colcon build), and source the workspace. Have you done it? Please show the "git log" command output if the problem persists. |
|
i downloaded the repo again and build the packages , and source it , then i ros launch and same errors again , i will try it again |
|
unfortunately the same problem , i don't know the git log . in the terminal i wrote git log , but this found "fatal: not a git repository (or any of the parent directories): .git " |
|
i asked chatgpt it said that "suggests that ROS 2 is trying to find an executable that does not exist or is not in the system's PATH" and asked me to check if the package have any axecutable by this command "ros2 pkg executables hoverboard_demo_bringup" and no files has appeared , is this true ? |
|
i made all files in hoverboard_demo_description executable , then try ros2 pkg executables hoverboard_demo_description no files has appeared , it this right to happend , i'm not an expert in ros so help me |
|
@ayahelmyy please go through the following steps in a fresh ros2 foxy workspace (in the src directory) git clone https://github.com/DataBot-Labs/hoverboard_ros2_control.git .
git checkout foxy
cd ..
rosdep install --from-paths src -y --ignore-src --rosdistro foxy
colcon build
source install/setup.bash
ros2 launch hoverboard_demo_bringup hoverboard.launch.pyAfter that, you should have a result similar to this one:
|
|
ok wait |
|
this error found from the fourth command "rosdep install --from-paths src -y --ignore-src --rosdistro foxy"
|
|
i solved this command thank you , i will continue then i will tell you the result |
|
Please run the "rosdep update --rosdistro=foxy" command and install packages by rosdep again. |
|
finally the errors is solved but there is errors in rviz ,
|
|
|
|
Please disable rviz and joystick related nodes in the launch file. |
|
ok |
|
rviz still open , and in terminal found ,
|
|
there is an error also , it may affect on me ? |
|
Yes, it doesn't work. Let me debug it with Foxy. |
|
i wanna ask you some question , i need to use the hoverboard motors in delivery robot works autonomous , so i need the cmd_vel topic and the odom topic , i didn't found the odom topic and the package on ros1 there are many topics i didn't found it here ,
|
|
It doesn't work now, so you will have all the topics you need eventually :) Also, be careful of the ROS2 version you use. Foxy has reached its EOL (end-of-life), so it's not a good choice for the new project. |
|
can i use humble if i use jetson nano ? |
|
i knew why we use foxy , because the legal version of ubunto in our jetson is 18 only and we downloaded 20 by jetson hex image so we must use foxy |
|
and last thing if i need the odom topic like the first version of ros1 like this :
|
Yes, the project works well with the Humble and Jazzy distros. I am unsure, but you could use newer distros in a containerized environment (docker). Using the EOL ROS2 version for a new project is not a good idea.
You will have all the needed topics, but it has to run correctly. I will try debugging it with Foxy, but it's an EOL version, so I have to find time for it. Please check these links: https://github.com/dusty-nv/jetson-containers/tree/master/packages/ros The Humble EOL is set for May 2027, and you can use it with Jetson probably. Please try the above links. I didn't check it, but it may be helpful. Good luck! |
|
sorry for the late replay , and thank you eng. Robert Gruberski for your support . could i ask you about the odom topic , according to using autonomous mode in my project , i need odom topic to take feedback , what should i do if you package doesn't have this topic |
First time ROS2 user here so I apologize in advance for my lack of knowledge.
I am using Ubuntu 20.04 on Jetson Nano, I installed ROS2 Foxy. I then created ~/ros2_ws/src folder and cloned the repo in there.
I then ran colcon build and rosdep install --from-paths src -y --ignore-src from ~/ros2_ws and source the install/setup.bash and finally I tried ros2 launch hoverboard_demo_bringup hoverboard.launch.py and I can't figure what the error means
