I was thinking about an idea of a redundant UAV with 2 x APMs, 2 x RXs, Dual Servos/surfaces, 2 x ESCs and 2 x motors. The plane should be designed so that it could fly with only one motor if needed.
The idea of functionality:
- If something in APM(A) network fails or works not well the plane would automatically switch to APM(B) network.
- If one of the servos fails there would always be another servo and another surface to control the steering.
- If one ESC or engine fails there would still be another to go.
- If one RX fails the system could use the (B) network.
How the system detects a failure?
- (If both APMs had the same planned route and the working APM(A) detects that the plane has drifted too far away from desired flight path it would automatically switch to standby mode and let APM(B) network do the job?
- If APM(A) network RX looses signal the failsafe would automatically switch the board to standby and let the other network take the control.
- The idea would be that the other network would always be in active mode and the other one would be in standby mode.
I hope you could give some additional ideas to this draft philosophy of a Dual APM plane....
