intelligence in FC - understanding RISK ?

[adamengineering]

hi

i am not sure if the wookong-m has this type of intelligence, but if i create a mission flight plan with 4 waypoints and upload it to multirotor and while inflight the battery voltage drops and it seems that there wont be enough battery to complete the mission.

can the wookong-m FC not identify this, abort the mission and start the return home ? if not, can any FC do this ?

The way that I understand it is that the simulation mode on the GS is so that you can fly the mission and know if you have enough battery to fly it. If during the mission your power gets low the FS is suppose to terminate the mission and land the aircraft.

yes what you saying is correct but, i am trying to understand if more intelligence already exists in the dji FC , will it beable to calculate the route and understand that it doesn't have enough battery power and would abort the mission and start its route back to home. the situation about landing when battery is low is just a safety, more interesting for me if the FC has more indepth intelligence which i am now trying to understand if exists in this FC of DJI or any other FC in the market.

The FC would abort the mission only because the low battery is activated, and that would then put the aircraft into FS. It would only make it home if there is enough power left for it to do so. The simulator lets you set up your waypoints and then fly's it. You should know how long your flight pack will last with the weight of the aircraft. The simulator will tell you how long it will take to fly the mission and with that info you will know if there is sufficient flight time for the mission. You might have to do the mission in stages. The simulator helps you calculate the flight time of the route. This is only available with the data link and a lap top.

judging from your response i gather that the wookong-M FC cannnot actually do or is not that intelligent enough, is there any flight controller while in flight that can identify the waypoint mission it has to accomplish cannot be satisfied with the battery power it has left and then automatically make its way home ?

I have the 5 waypoint and the way I understand it is that the only way that the FC can know if it cannot complete the mission is when the batterie(s) get low. I don't think it can pre-aknowledge the fact. As said this can, as I understand it, be accomplished with the simulation mode on the PC. There is a blog on line, RCGroups.com, type in search, Wookong Owners, and there is a lot of info on that site. Or you could post your questions there and someone with more knowledge than I can help you. Sorry I can't seem to answer your question exactly. I hope the RCGroups will.

Im not sure that any shipping FC can do the projected remaining energy vs. projected required energy comparison you appear to be asking about. This would be a sophisticated judgement and would require a lot of information relating flight performance, flight conditions (wind speed direction) and specific battery performance all linked together. There's no such thing as a reliable analog of the fuel gauge for a gas-powered craft, for example. Not saying it couldn't be done, but WKM can't do it. It will just compare flight voltage with optional 1st and second level voltage thresholds you can set. It will then land or RTH and land depending on the options you've selected.

You would want something that actively tracked mAh used and voltage as well as flow and remaining to be flown vectors (length in 3 D, direction etc. ). Sounds like a job for open source fully programmable FC with substantial custom development work. But maybe it's overkill and simpler limits on flight time and voltage would suffice.

infact to a certain extent i understood now what you saying, i read your previous reply a few times. in the voltage menu first level voltage has a go home feature. before, i use to just let it alert me with a specifc colour LED blink. i think i can set the first level voltage a little lower and make it "go home" once first level activated in that way i should beable to sort of achieve what i need.

thanks for the help , i wil try out the rcgroup as well.
