There is a fantastic resource that’s been released by the author of Pythonprogramming.net for programming the GoPiGo in Python. He shows you how to get started with the GoPiGo in Python, and works his way up to using the missile launcher and using camera vision.
If you’re just starting out with either Python or the GoPiGo, we really recommend you check it out!
