I recently got into ROS2 and simulating robots and I started with the official Nvidia guide that talks about the turtlerobot3. I downloaded ROS2 Humble (for Ubuntu 22.04) and everything according to their guide, but when I git cloned the repo and tried the xacro command to convert .xarco to .urdf for Isaac Sim, I get the following error:
Why isn't it detecting the "turtlebot_description" folder?
These are the commands I run every time I open the terminal (I should place them in bashrc so that I don't have to do this again and again):
source /opt/ros/humble/setup.bash
export TURTLEBOT3_MODEL=burger
cd .../urdf
xacro turtlebot3_burger.urdf.xacro > turtle1.urdf
And then it gives me this:
"package not found: "package 'turtlebot3_description' not found, searching: ['/opt/ros/humble']"
And I even tried placing the file in $ROS_PACKAGE_PATH so that ROS can find it with:
export ROS_PACKAGE_PATH=/user1/codes/turtlebot3/turtlebot3/:/opt/ros/humble/share
And if I do
echo $ROS_PACKAGE_PATH
I get:
/user1/codes/turtlebot3/turtlebot3/:/opt/ros/humble/share
Which is correct! It should detect the turtlebot_description within the turtlebot3 folder. But it doesn't. So what am I doing wrong?
In the Nvidia docs, they do mention that we should place any package dependencies in the ROS_PACKAGE_PATH, but they don't mention how we're even supposed to do that...
