NoVa Quadrotor

NoVa is a new quadrotor that uses Paparazzi hardware as well as software. The goal of this project was to create a durable and affordable quadrotor that integrated with the existing paparazzi project. Custom airborne software links NoVa to the paparazzi GCS. Segregating its specific code will allow users to fly their fixed wing UAVs in the same up to date CVS tree as NoVa.

Hopefully soon you will see more updates, pictures, videos, and hopefully build plans. For now let me leave my email akochevar@gmail.com. If you have any questions feel free to drop a line. Enjoy the pictures!

UPDATE 10/07/08: With some coaxing from a buddy, I implimented the kalman filter from Rotomotion tonight. Seems to function similarly to my comp filter, but tighter, with less overshoot and historysis. Ill fly it this weekend and see if it makes things better.

Also, I have a new LEA5H gps on the way, along with an ultrasonic altimeter. Should be a couple fun toys to play with.

More info on Paparazzi VTOL applications can be found on the Booz page.
