- in practice this is mostly useful for identifying incorrect rotations
which we mostly have in 45 degree increments
- handling a vehicle on the ground can easily disturb one mag by more than 30 degrees, so this is often distracting noise
- the values of the parameters GND_MAX_ANG and GND_WHEEL_BASE are outdated. They belonged to another Rover setup.
- in the mixer file rover_diff_and_servo.main.mix the steering was controlled by roll, but in PX4 rover steering is controlled by yaw. And this was the reason why the attitude control did not work correctly
- the DF Robot GPX:Asurada rover has actual a steering angle of 60 degrees. And and wheel base of 0.17m. Parameter values in the airframe file are changed to this values
because we need to have SITL simulation as realistic as possible
compared to a real flight with default settings such that we
either fix the problems or adjust the defaults already in SITL testing.
- avoids the need for ekf2_timestamp publications by q and lpe
- adds logger to the lockstep cycle and makes it poll on ekf2_timestamps
or vehicle_attitude. This avoids dropped samples (required for replay).
- IMU integration move from drivers (PX4Accelerometer/PX4Gyroscope) to sensors/vehicle_imu
- sensors: voted_sensors_update now consumes vehicle_imu
- delete sensor_accel_integrated, sensor_gyro_integrated
- merge sensor_accel_status/sensor_gyro_status into vehicle_imu_status
- sensors status output minor improvements (ordering, whitespace, show selected sensor device id and instance)
Before #14212 the velocity control gains used in the multicopter
position controller were defined as a scale between velocity error in
one axis (or it's integral and derivative respectively) and the unit
thrust vector. The problem with this is that the normalization of the
unit thrust vector changes per vehicle or even vehicle configuration
as 0 and 100% thrust get a different physical response. That's why
the gains are now defined as scale between velocity error
(integral/derivative) and the output acceleration in m/s².
- skip avionics rail voltage check when USB connected
- skip forced reboot on USB disconnect if circuit breaker set
- avionics voltage preflight check don't silently fail if system_power unavailble
- explicitly set supply check circuit breaker (CBRK_SUPPLY_CHK)
This adds a sitl target and aiframe configs for the r1_rover, which is a differential rover example for SITL rover. The model is based on the aion robotics r1 rover
