I made my first autonomous flight today. I am very happy to achieve this result!
It is only a 30 seconds flight, but 100% autonomous! Lift and landing are still under manual control.
It is not perfect, the control goes wrong after 30 or 40 seconds. I have to work a lot to obtain better results, but this first flight is a big improvement in my project!
BOB4 estimates its position with only its onboard sensors : 4 sonars, one 3D magnetometer, one 6DOF IMU.
The computing is only onboard, without any external aid.
All computation is done on an “Embedded Master” motherboard with .Net Micro Framework.
I have designed this UAV alone. The hardware and the software is 100% home made.
