M500 driff when flying VIO indoor navigation.

[Vũ Văn Long]

Hello, as the topic name when I starting to fly indoor nav with M500 VOXL frame, the UAV not go up straight but driff to the left side or right side (randomly). I also checking the Local_position_NED is 0,0,0 before the flight.
Here is the "systemctl status voxl-vision-px4"

and when i test the odometry with "voxl-test-vision-lib -o"

pls give me some advice.

Hi @Vũ-Văn-Long ,

In order to better understand the setup, are you flying in offboard mode or manually through RC in position mode?

Thanks!

@modaltb hi, i'm just trying to take-off manually though RC in position mode.

every step is correct with the manual document. Here is what we do with the UAV. In the last week i had tested the UAV load in position mode and it's work well, after that i also tried with MavROS node to take-off UAV in Offboard mode. we would set the altitude to take off is 0.5 m but the UAV takeoff higher than 1m much (i had build rosnode after launch).
But it was other problem, in this week we had installed a asus xtion camera and a raspberry pi at the bottom of m500 frame, then trying to maunally filght at position mode but the driff has occurred.

thanks for sending the video. We'll look at this in detail. Can you please dump /etc/modalai/voxl-vision-px4.conf and provide? Can you make sure offboard_mode: "off"?

@Chad-Sweet oh my godness. My mistaken, i didn't realise that before that i had configured UAV off board mode. when I check the /etc/modalai/voxl-vision-px4.conf the offboard_mode ="figure_eight" => so that's why it's cause the problem here. anyway, it's work again, thank you so much for the effective support
