I'm talking about my own experience in this thread and I'm not saying that a software bug may be the only cause for all the flyaways or crashes... A flyaway in ATTI mode can be triggered by hardware failure, pilot error or other reasons.
For now, in my case, I rule out hardware issues (except maybe a weak GPS antenna), because I had other flights without a glitch after these incidents.
If I were a quad manufacturer, I would try to collect data logs from users to understand better what was going on in cases of accidents. As a software developer you need to get a repro to fix a bug (and get as much data as possible - software and hardware version, datalogs, etc). A diagnostic software may prevent hardware issues, before they occur. By collecting data when the quad is in a GPS mode in hover, you can measure how well the 4 motors are performing, if there are some sensor errors, etc. I know a team in charge of developing "preventive maintenance" for ATMs - that is they were analyzing data to figure out when ATMs may have problems in the future, in order to minimize maintenance costs and reduce the number of service trips for their support engineers. |
