ROSbot XL demo process given prompts. Help.

[kaanoz1]

As a group we are trying to run RAI in order to accomplish our project. As for testing and initialize our project we decided to launch the demo of launch ROSbot XL demo. We can completely launch the game engine and GUI and allow us control to robot by prompts without any errors. But for some reason our robot rejects EVERY prompt that we entered and it is impossible to move our robot by prompts. I will send the logs. May anybody help?

Hi,
The fix might be just as easy as switching to a better model. Llama3.2's tool call capabilities are subpar. Ideally, try gpt-oss-20b or a model from qwen3 family

[kaanoz1]

First off, thank you. But is there any qwen models that you can suggest for good performance and tackle this problem? qwen3:8b embeddings is not supported. We are trying qwen3:8b for complex tasks but it is throwing an error of "Action was not accepted". By the time, we are not able to use gpt model that you suggested.

Log records that we encountered:

Please try changes from this branch: #754

[kaanoz1]

We cloned from that branch. And it worked we can write queries without any "not accepted" action. But now, even though there are no errors, robot does not work or do anything. May you inspect? Maybe we can use the qwen model that you used (or are using even now) in the screenshot that you sent.

I am sending the logs and screenshots about this issue.

[bahardemirkan]

Hi, @maciejmajek I have the same problem. I also cloned this branch but llm can't call navigation tools. I'm using gpt-4o-mini and gpt-4o models. Before cloning the model, I had the problem in the image.

[Juliaj]

But now, even though there are no errors, robot does not work or do anything.

@kaanoz1, we'd need more details to investigate. Could you provide following

• an example prompt that you were running
• expected result, and what you were actually seeing

I've run the demo with Qwen3:8b and was able to get the rosbot to navigate to kitchen successfully.

[Juliaj]

I also cloned this branch but llm can't call navigation tools

@bahardemirkan, were you seeing any errors from the terminal that you started the demo ? For example, on my machine, I see the following with gpt-4o-mini which shows a successful run with the prompt "drive to kitchen"

Also, after you start the demo, on a new terminal, and run following commands and let me know the results.

# --- check on nav2 package install --- 
$ ros2 pkg list |grep "nav2_bringup"

# --- check on the nav2 related nodes ---
$ source /opt/ros/jazzy/setup.bash  # replace the jazzy with your actual ros2 distro
$ ros2 node list |grep server

[bahardemirkan]

Hi, @Juliaj thank you for your answers.
I managed to move the robot by manually starting nav2 on a new terminal. The only issue here is, robot can't go over the obstacles. It gets stuck. Here are the results:

Also, here are the results for running the commands you recommended:

This is the error I got in the simulation terminal:

[Juliaj]

@bahardemirkan, thanks for sharing details with nav2. I don't have a humble setup. With Jazzy, I have these nodes for nav2 stack

$ ros2 node list |grep server
/behavior_server
/controller_server
/docking_server
/planner_server
/route_server
/smoother_server

That said, humble nav2 may work differently than Jazzy, so your setup may not have any problem.

Regard to

It gets stuck. Here are the results:
...
2026-01-23 12:34:21 192fc81e95c8 rai.agents.langchain.core.tool_runner[137152] INFO Error in "navigate_to_pose_blocking", error: 'NavigateToPose_Result' object has no attribute 'error_code'
...

There is an issue with these RAI code lines,

rai/src/rai_core/rai/tools/ros2/navigation/nav2_blocking.py

Lines 89 to 90 in d506429

	if result.result.error_code != 0:
	return f"Navigate to pose action failed. Error code: {result.result.error_code}"

Looking into this briefly, I believe send_goal returns NavigateToPose.Result which has error_code. In other words, a potential fix would be just calling

if result.error_code != 0:
        return f"Navigate to pose action failed. Error code: {result.error_code}"

If this works, make it into a PR.

Note, this may or may not resolve your issue with nav2 or the demo. For additional help, you may need to reach out to someone on discord with humble setup. Cheers.

[bahardemirkan]

Hi, @Juliaj I changed my ros distribution humble to jazzy. Things have gotten worse.

Sorry to hear that, can you tell me a bit more on how you switched from Humble to Jazzy.

[bash-1] [ERROR] [component_container_isolated-1]: process has died [pid 57073, exit code -4, cmd '/opt/ros/jazzy/lib/rclcpp_components/component_container_isolated --ros-args --log-level info --ros-args -r __node:=nav2_container --params-file /tmp/launch_params_ypzi_jlh --params-file /tmp/launch_params_dzhvf27m -r /tf:=tf -r /tf_static:=tf_static'].

Exit code -4 usually indicates a segmentation fault (SIGSEGV) or illegal instruction (SIGILL) which could be caused by mismatched dependencies. Here is what we can find more,

• Reboot your machine if possible. Or terminate all leftover processes.
• Restart the demo, wait it is fully loaded, nav2 stack takes time to load, then run

$ ros2 node list |grep server

let me know what you have on your side.

Actually I completely reset my machine, switched to Ubuntu 24.04 and downloaded Jazzy from scratch.

Exit code -4 was not the big problem for me, these are bigger I guess:

I rebooted my machine. Now, I'm setting up the environment again. The errors above are newer I've never had them before the last merge.
