Hello,
We ran into a bit of a mishap when flying our Solo. We had the Solo on an automatic mode (grid survey). When we set it to return to home, the solo flew up and then kept flying up and up and up. It didn't know it was already 50 ft off the ground.
The reason? Well, we are using a Lidar rangefinder to keep it a constant distance from during the grid survey. We are using green cube with the new arducopter so that we can use terrain follow mode (in mission planner we have the Altitude control set to "Terrain". But it appears to use the lidar as well when it tries to return to home and land, and it registered an error when it got too high.
When it started flying up out of control I tried to use the controller to guide it back to the ground, but I could not force it to switch to manual. So my question is how can I override the return to home command and switch to flying the drone manually? So I can bring it down safely and regain manual control?
Thanks!
P.S., the issue with the lidar I think was it flew into some fog, so the lidar reflected off the fog and the drone thought it was too close to the ground and tried to continue going upwards before returning to home. You can see in the attached plot, that after a grid survey (at 2 meters), it flies upwards (the spike to 15 meters) before entering the fog and the lidar registering it too close to the ground. It then continued to ascend. Eventually I managed to start bringing it down manually (I think by holding the fly button), but it ran out of battery and fell from about 250 feet. I'm surprised it was still mostly intact (soft ground). Is there a better failsafe way to regain manual control in any situation?
