EKF updates

testing mavlink cameras with SITL

[Craig Elder]

Copter (Randy)

• A couple of minor fixes went into RC12.  No other updates have been required so this will be the release firmware - v3.3.

TradHeli (Rob)

• A new branch of TradHeli based on 3.3 RC12 and rebased from F. Heidberg.
• Interlock estop race condition has been fixed.
  
• Servos weren't moving after arming and motor getting up to speed in Acro mode.
• Implementing an expo function with Acro
• Another release candidate coming towards the end of the week.

Plane Release (Tridge)

• Plane v3.4 Released
• EKF is the default
• Last release supporting APM1/APM2.
• Would like to get PX4Nuttx, UAVCAN and PX4Firmware updated.
  

MAVExplorer (Tridge)

• Now available for Linux.  We would love to make it available in the other GCSs and other OSs
  
• http://dev.ardupilot.com/wiki/using-mavexplorer-for-log-analysis/
• Paul has supplied a set of EKF graph's for EKF analysis

EKF (Tridge)

• New one is in master
• Its being run in the auto-test system
• Set EK2_ENABLE = 1
• Set TERRAIN_ENABLE = 0 (so you can get enough memory on a pixhawk as both EKFs will be running)
• AHRS_EKF_TYPE = 2

Testing MAVLink Cameras in SITL (Jaime)

• Going to write a guide on how to click a MAVLink camera to SITL

[Robert Lefebvre]

Would like to clarify the Tradheli stuff:

New branch of TradHeli based on 3.3RC12.

- includes major changes from fhedberg and myself.  Most important change here is "live" helicopter servo setup while disarmed.

- Motor Interlock/E-stop/Arming race condition fixed.

- Fixed bug where servos stop moving *between* arming in Acro and Stabilize mode, and the rotor achieving speed.

- Stabilize Collective function improved to be a 3-segment line to allow for shallow slope around hover, as is commonly used by non-UAV heli pilots.

- Acro Collective function added to create softer response near zero pitch, for same reason.

- Stab Col and Acro Col smooth blending function to avoid jumps in collective pitch output when changing modes.
