wtf is raspberrypi_objectracking_2dof_cpp-?

This is the second version of a small robot project built on the Raspberry Pi that tracks an object using a camera, written in C++. The first version of the project, linked from this README, could only move in one direction, but this second version adds a second degree of freedom, meaning the robot can now aim or move in both the x and y directions at once instead of just one. The README itself is quite sparse. It does not explain how the object tracking algorithm works, what hardware beyond a Raspberry Pi and a camera is required, or how the two directions of movement are physically actuated. The author says that tutorials and a list of parts to build the physical robot, referred to as a cad list, are coming soon but are not yet included. What the README does provide is a short list of external software the project depends on: the C++ version of OpenCV, a widely used computer vision library, set up for the Raspberry Pi, a library called lccv for working with the Raspberry Pi's camera, a library called PIPCA9685 for controlling hardware over the Raspberry Pi, likely used to drive the servos or motors that move the camera in two directions, and a VNC viewer, which is a tool that lets you remotely view and control the Raspberry Pi's screen from a separate computer. Because the README does not go beyond this list of links, someone interested in building this would need to install those dependencies first and then look directly at the source code to understand how the tracking and movement are implemented, since no further explanation or instructions are given here. No license information is present in the README.
