• Fail to load library when trying to write a custom hardware interface for Arduino to control servo motors
  3 projects | /r/ROS | 10 Mar 2023

  Hello, I am learning ROS2_control by trying to wrtie a custom hardware interface to control 2 servo motors via Arduino. I am referencing these two repository ros2_control_demo_hardware and diffdrive_arduino when trying to write my code. I can successfully move my pan-tilt robot in simulation (Gazebo) and fake hardware mode. However, I failed to move it in the real hardware after a week of trying. below is the error i got when i ran the launch file. Can anyone tell me where i did wrong and how should i modify my code to correct it? Many thanks. Here is my code here

• need help to find resources to learn from

  If you're wanting to integrate with an existing robot it will depend very much on the hardware you've got. On the off-chance you are using a DC motor controller with an Arduino, I have a hardware interface repo here that will integrate that with ros_control/ros2_control however it is still very much under development and not documented, so you will probably have trouble using it if you're not already fairly familiar with ROS and C++.
