Hello, I have been following along and thanks for your great efforts, everything had been working fine with me until this point. When I tried the laser scan at rviz with ros2_control, the scan moves totally with the robot, the dots move with the orientation of the robot not just wiggle as the small problem but it totally moves. When I switch to gazebo_control everything comes back to normal, not sure what the problem can be?
I am also facing the same issue. ros2 launch articubot_one launch_sim.launch.py everything is working fine. when i launch ros2 launch articubot_one launch_robot.launch.py i am having controller_manager issues . I did not connect my joystick. and my physical robot has no response.
FYI. In ROS2 Humble, I could perfectly run with just âspawnerâ not âspawner.pyâ. It is a little change as you mentioned.

How did you fix the Hardware_interface issues in Humble using GitHub - joshnewans/diffdrive_arduino: A simple ROS Control Hardware Interface for differential drive control of robot whose motors are connected via an Arduino (or similar microcontroller). this Diffdrive_arduino . I was stuck here.
Hi, I facing some issue with gazebo ros2 control package. I followed the instruction for the ros2 control and launch the launch_sim.launch.py everything work perfect but could not connect with gazebo_ros2_control
The error msg:
[gzserver-2] [ERROR] [1691414356.585613673] [gazebo_ros2_control]: Error parsing URDF in gazebo_ros2_control plugin, plugin not active : text not specified in the min tag
because this I wasnât able to connect with hardware interface
error msg:
ros2 control list_hardware_interfaces
Could not contact service /controller_manager/list_hardware_interfaces
Can you guys help me to figure out what mistake I have made.
Thank you for your help.
Hey Josh,
I am having trouble running the command ros2 run controller_manager spawner.py diff_cont
it is saying that there is no executable found. I have installed and done everything the same as you up until that point.
Any suggestions?

Hi there, I am very thankful for your robot tutorial. Can you let me ask if skipping the tutorial section in video 12a will have much impact on subsequent tutorials. I donât really need great precision
Can anyone help out with this problem . I am also facing the same issue

Hi @Mohammed_Thabrez
Looks like you are using ros2 iron, this tutorial is for foxy, but it is updated to humble, see https://www.youtube.com/watch?v=qoj5_fVBPII for the update
Try the humble branches of the github repositories.
