how do i integrate the ultrasonic sensors with the drone? apart from landing the drone I also want to navigate it indoors by avoiding objects.
step by step instructions will be helpful
1) GPS - to proximitely (about 15 meters) find the land
2) Ultrasonic sensors - to precisely (1 inch) find the land from altitude about 6 meters
3) Pressure altimeter (about 15 cm) - to find the land second time
I'd find the land descending with ultrasonic sensor with normal UAV speed. Then I'll lift up and make second pass for landing with low speed knowing the height very precisely.
I think two passes for landing make it very carefull.
Infrared sensors have a similar problem where the varying reflectivity of different surfaces can make things effectively invisible.
Other alternatives include laser altimeter (very expensive), gps, and barometric altimeter. The Piccolo autopilot is able to do autonomous landing using gps and barometric altitudes. And I expect that it could do it using just the gps altitude.
