I have written an intuitive flight simulator in Python for controlling quadcopters. In particular, you can try the Formation Control algorithms from my thesis, or to learn how to control the altitude and attitude of one these machines.
I have added a new lesson in the Artificial Intelligence for Mobile Robots course. This time I show, mathematically and with actual code, how to emulate the behavior of fish schools or flocking birds.
One of my formation flight algorithms applied in the real world. Enjoy!
My guide about how to build your own bungee launcher. Basically you can throw whatever you want, I find it useful for my fanjet.
