ROS2 Robot Control - Step 1

This is a simple project to begin working with a ROS2 Humble/Foxy U20/U22 programmer. This is Step 1 in a series of sub-projects. In the attached photo is a 2-wheeled robot with a 3rd omni-wheel for inherent balance. The 2 motors are controlled using a command <velocity,L,R> passed over a USB serial port to a Speed XIAO motor controller.
Future steps will make use of the NVIDIA ZED Box, StereoLabs SDK, and ZED 2 stereo camera.
