Okay, once attached is when we can start development. We will need to make a service by way of a .service file, a couple of software examples, and use systemctl to make our service run on boot. For the service file, go to /etc/systemd/system. Make a .service file by using your favorite editor, nano for instance, and use this idea for a .py file named MotoCape.py:
[Unit]
Description=Whatever You Would Like to Describe about Your File
[Service]
ExecStart=/The/Path/To/Your/MotoCape.py
[Install]
WantedBy=multi-user.target
Once we have our file, .service file, save it and exit. Notice in the [Unit] section...there is a Description directive.
I described what you should put there but have at it.
The best way to add content to the Description= line is to make your description as well understood as possible.
Just nothing all that vague should do.
In the [Service] section after ExecStart=, the PATH to your file, whatever type of file it may be at this point, should start w/ your working directory and end w/ the file being run on boot.
On the [Install] section after WantedBy=, type multi-user.target. There are many recommendations on what to read and where to read it.
I have found this site to be the online page w/ the most info: https://www.freedesktop.org/wiki/Software/systemd/.

Please keep in mind that when applying power to the MotorCape, the motors will only move if the BBB, BBGG, or BBBW are plugged in via barrel jack.
Although I am testing with a new board from beagleboard.org (BeagleY-AI), you can use this source code and attached files with the BBB and/or am335x style of SBC.

I got source from adding, making additions, and reading (and AI)...
