Driver working on PC but not in Raspberry PI 4

[Agri-Mechatronic]

Hello, first of all thanks a lot for this repo.

Do you know why driver is working on PC which runs ubuntu 18.04 with ros melodic but it does not run in Raspberry pi 4 with raspios and ros melodic installed?

I am getting the error that it is failing to run hoverboard_joint_publisher and hoverboard_velocity_controller and it is saying that they don't exist. I can see other topics when I do rostopic list like voltage, temperature, pid etc... , but I can't see hoverboard_velocity_controller/cmd_vel and the others related with velocity controller, so I can't send velocity commands to wheels.

Does this driver need also other packages to be installed, or it will work even if I have only this repo in my catkin ws?

Thank you...
