Problem with /odom data - no data received.

[CycleMark]

Robot Model

Turtlebot4 Lite

ROS distro

Humble

Networking Configuration

Discovery Server

OS

Ubuntu 22.04

Built from source or installed?

Installed

Package version

I'm actually using Jazzy on R Pi5.

I can see data and topics from the iCreate and those from the Pi /scan etc no problem. But I'm getting nothing on the /odom topic.

Starting the robot with:

ros2 launch turtlebot4_bringup lite.launch.py

rplidar etc come up but when I start

ros2 launch slam_toolbox online_sync_launch.py params_file:=/home/ubuntu/ros_ws/config/mapper_params_online_async.yaml

It complains:

[slam_toolbox]: Message Filter dropping message: frame 'laser' at time 1736352837.937 for reason 'discarding message because the queue is full'

Which I've figured out is because there is no odom tf or data being sent out.

Possibly related when I run

ros2 run teleop_twist_keyboard teleop_twist_keyboard --ros-args -p stamped:=true

The robot does not move.

Seems like there is a process missing. Can you please advise?

Thanks

Mark

Hi @CycleMark
Thanks for writing in - sorry to see you've encountered this concern. Can I get some more info:
Can you please replicate and share Create3 logs and full terminal outputs of processes running?
Please also provide the firmware version of Create3?
Best regards,
Rusty
