I've been using ROS for a while but have only recently wondered - is it possible to automate the process of generating/filling in the depencies in package.xml and CMakeLists.txt files? From what I understand, this is a manual process, with ros2 pkg providing some help with flags like --build-type or dependencies.

I'm currently working on creating a robot for a capstone that moves in an environment where humans will be milling about indoors and will occasionally approach the robot to interact with it. My first thought was to detect people with AI using a depth camera with RVC2, but eventually found SLAM as a technique that sound... |
Image data is received and transmitted from Arduino through spi communication. In Arduino
