ROS Common Issues

Writing down a list of the common issues that I run into with ROS, which have wasted me hours and hours of time:

• QoS incompatibility issues through the Create3 at work
• QoS instead of the 10 queue size for a message seems to fix the issue not seeing topics on the DeepRacer…? I still don’t fully understand why that is the case
• When first creating a package, make sure to modify all the necessary files! This is mainly the CMakeLists.txt. If your launch file or config file is not found, you need to also add them in the CMake. Refer to my Pure Pursuit code for reference.
