Thanks for the kind words! I'm not doing it for profit, just the desire to share something that took an unexpected level of effort for me to sort out.
Eventually I plan to open source the robotics curriculum that spawned this project, along with some other stuff related to starting a new school (something I'm working on with a team that was originally inspired by the XQ Superschool competition [1]). I want to run it through its paces with some real children first to make sure it's not completely off base though.
