Unfortunately, I'm waiting on the publication of the MOOC and course materials to find out.
It looks like the latest book, "BeagleBone Robotics Projects, 2nd Ed", https://www.amazon.com/BeagleBone-Robotic-Projects-Second-co..., came out in June and I haven't had a chance to look through it. The 2014 book, "Mastering BeagleBone Robotics", by the same author walked through multiple robotics examples implemented using Python and didn't involve the PRUs. Using only Python, there were examples of a rotary aircraft, fixed wing aircraft, sailboat, wheeled vehicle, and computer vision tracking.
My understanding is that TI only recently began improving the PRU documentation to make it more accessible and that Code Composer and other tools TI has created for working with the PRU are maturing slowly. I've never tried using it. Here's the PRU page on the BeagleBone wiki: https://elinux.org/Ti_AM33XX_PRUSSv2#C_Compiler
Another thing I've never tried, but that might be of interest to HN readers, is the Nerves project for Elixir development on single board computers including BeagleBone Black. https://hexdocs.pm/nerves/targets.html
