I need to get an autonomous quadcopter above a bucket (60x40 Cm) and deliver a payload inside. The idea is to get near the bucket using the GPS. Then guide the copter by putting some IR emitters around the bucket and receivers on board.
I have an arduino board in the flight controller but I might need another one. I will use Mission Planer software to get near the bucket and control the copter but to find the exact position of the bucket I probably need to implement another code or use another software, any ideas? I guess I need a program that makes the copter to move towards the signal is stronger (keeping the altitude). And when the signal is weaker in all directions, it means the copter is upstairs.
I also don't know the circuits that would do for the emission and reception of the signal and I heard that infrared may not work outdoors...
Once the copter is above the bucket, it won't be a problem to trigger the payload using a solenoid valve and a relay.
