• With the complicated competition flight system, we need high-level software to aid us in the coordination of different sub-systems. The flight system EFS came out last year has a fantastic and delicate architecture, but it also takes way longer time than we expected to accomplish. We want to have a high-level system with simpler logic that can fly a drone with the aid of Pixhawk as the backup plan for competition.

• This is the rough idea of how it is gonna work

• please point out the flaw in this type of design and the missing part of the system

• In brief, the system has two running modes. The manual mode and auto mode.

• The mode the system is currently running depends on the PPM instruction we fetched first.

• If the PPM tells the drone is in manual mode, then only the manual PPM instruction is sent to PX4

• If the PPM tells the drone is in auto mode, then try to fetch the auto command from RFD

• Fetch failure will cause the system to transition to manual mode

• If fetch success, the ZP3 will send the auto command to PX4 to process. PX4 will send the telemetry data back to ZP3. ZP3 then processes it with PM and sends it to RFD.

🗓️ Timeline

• The first stage of the development of simple SM would be building the PPM protocol bridge such that the drone will be flyable by manual control. The anticipated first flight test will happen by the end of May.

• Then it can move on to the second stage, which is testing and fixing TM and Mavlink so that the drone can fly autonomously. The flight test for the autonomous flight will be in mid-June.

• The actual time span can be longer since there will be a lot of components involved and they all need testing and debugging.
