Following along this series, and I have to say that this is a bit outdated. Because after trying my own code I noticed that if I use ros-humble with humble branches for `diffdrive_arduino ` and `articubot_one `. It will not work since there is no `DiffDriveArduino` instead there is "DiffDriveArduinoHardware". Another thing is after you fix that the DiffDriveArduinoHardware class crashes because it cant find `timeout_ms` key since there is no such thing in `ros2_control.xacro`. After that is fixed it still fails to launch and complains about `state_interface` order for wheels (position first and then velocity).

Yes it's unfortunate the way a small software update can break things :( I would have expected the humble branches to work though - I cover this in a fair bit of detail in this video kzitem.info/news/bejne/q2Zo0HmBmql2aIo so maybe check that out if you haven't already?

@@ArticulatedRobotics I understand that. I will look at that video later once I will be finished with the series and I'll need to implement my own hardware. Btw do you have any videos or blog posts on communication troubleshooting between two machines using ros2? Because for some reason my PI sometimes won't receive any data, but when I use "ros2 multicast" PC can send and receive, but the pi can only send when this happens.

Hi, thank you for your videos. So I'm getting this error when I build the diffdrive_arduino package: Starting >>> diffdrive_arduino --- stderr: diffdrive_arduino CMake Error at cmake_install.cmake:95 (file): file INSTALL cannot find ".../src/diffdrive_arduino/description": No such file or directory. If I remove the description from the CMake file, the compilation works well... why do we need to install this directory?

Thanks Mateus, you are absolutely right and I thought I had pushed that fix but apparently not. An earlier version of the code had an example xacro in a descriptions directory which I later deleted, but forgot to delete the install line. The fix should be pushed now - thanks for bringing it to my attention!

Hi Josh! I'm still not clear about your diffdrive package. I have been through this series and suddenly jumped up to this package at this video. As far as I know for HW level communication you are using serial_demo_msg package. I have been developing serial_demo_nsg to listen to Twist messages and pass them through the robot. and this stage come up and makes me confused. and this package is based on C++. I understand a little about all those cmake stuff. but can you give more explanation about diffdrive package, please?

Hello, your tutorial is great and I've been following it to a T! Though, when using the teleop keyboard something is causing the robot to drift to the left in real life and in rviz. It also happens when I used the miniterm command to test the encoders from your motors video. The left encoder returned a different value than the right encoder. Do you know where in your code that could be causing that? Thanks in advance!

Hope that helps :)
