Is there a way to have my truck go into hold mode if the current being drawn exceeds a limit that I set?
I had my truck doing a mission and it has been pretty rock solid lately. I had it do 120 laps yesterday without a hitch then today I had it out there and it was doing fine then work called and I had to get on a troubleshooting call. I wasn’t paying any attention to the truck and when the call was done, I noticed that it was stopped on the map. I look out and it ran into an 2" pole (the only obstacle even close ) and seemed to be stuck. I went out and the motor was letting the magic smoke out because the truck, try as it may, could not drive over a metal pole.
So I’m looking for a way to have it stop trying to reach a waypoint if a condition is met. In this case it would be excessive current draw or not reaching a waypoint in x amount of seconds.
I found MOT_BAT_CURR_MAX but that just limits the max current.
Ok, that’s a bit over my head at this point. I’ve done some Arduino experimentation and some linux bash scripting but never touched lua. I guess I can look into that.
have a look at the example scripts, there is probably something there you can edit to make work, your not wanting anything that complicated.
sonmething like
local max_current = 99
local current = current_amps
if (current>max_current) and (vehicle:get_mode() == 10) then -- if mode is in auto
vehicle:set_mode(4) --set mode to Hold
gcs:send_text(2, string.format("Battery warning:OVERCURRENT PROTECTION))
return update, 1000
The first part is simple enough Does this part write a message to the log or messages section or something? And it looks like the last line sets a loop for 1000ms? This don’t look too bad, normal stuff. I just have to learn the syntax.
@mikez104 were you able to configure it and get flash warning messages?
I’m trying something similar where I want ardupilot to display a pop-up window or a warning message when the current draw of my drone is exceeding 100A.
