I am using holybro pixhawk 6c. The chosen airframe is Aion Robotics R1 UGV. The pixhawk is calibrated.
I tested the pixhawk with QgroundControl and viewed the odometry data using “listener vehicle_odometry” in the MAVLink console.
When I went upstair, the z position was showing negative value. When I went downstair, the value of z position was positive.
Is it a normal situation for pixhawk? Should I use negative z position when I am going to convert it from “px4_msgs/msg/VehicleOdometry” to “nav_msgs/msg/Odometry”?
