I am currently integrating VIO on our drone, but have experienced an odd issue. While flying today, the drone was maintaining a stable hover and flight path in position mode. However, as I went to land, the drone began to unexpectedly takeoff vertically. I tried to actively lower the thrust, but the drone was not responding and I had to hit the kill switch. We are using an Intel camera for VIO and have followed the PX4 Wiki: https://docs.px4.io/master/en/computer_vision/visual_inertial_odometry.html
https://review.px4.io/plot_app?log=e7b9df7c-cf4c-4441-b314-bc001c5142a5 This is a copy of the flight log. If you look around the 6:10 mark, you will see that the thrust jumps to 100. It’s as though the flight controller received a 100% throttle input, but this is not something I commanded from the transmitter. We have had this issue more than once. Has anyone else experienced this before?
Thanks in advance for any help.
