a) feed-forward controller and jerk limiting should result in slightly snappier performance and smoother take-offs
b) vehicle climbs automatically to PILOT_TKOFF_ALT alt when taking off in Loiter, AltHold, PosHold, Sport (disabled by default, pilot's throttle input overrides takeoff)
c) PILOT_THR_FILT allows enforcing smoother throttle response in manual flight modes (defaults to 0 = off)
d) TX with sprung throttle can set PILOT_THR_BHV to "1" so motor feedback when landed starts from mid-stick instead of bottom of stick
e) GCS can initiate takeoff even in Loiter, AltHold, PosHold and sport by issuing NAV_TAKEOFF mavlink command
2015-05-01 23:55:38 -03:00
4) Stop flight mode - causes vehicle to stop quickly, and does not respond to user input or waypoint movement via MAVLink. Requires GPS, will be renamed to Brake mode.
2015-05-01 10:01:27 -03:00
5) Aux channel features:
a) Emergency Stop - stops all motors immediately and disarms in 5 seconds
2015-05-01 23:55:38 -03:00
b) Motor Interlock - opposite of Emergency Stop, must be on to allow motors to spin motors, must be off to arm
2015-05-01 10:01:27 -03:00
6) Air pressure gain scaling (of roll, pitch, yaw) should mostly remove need to re-tune when flying at very different altitudes
7) landing detector simplified to only check vehicle is not accelerating & motors have hit their lower limit
8) Loiter tuning params to remove "freight train" stops:
raising WPNAV_LOIT_MAXA makes vehicle start and stop faster
raising WPNAV_LOIT_MINA makes vehicle stop more quickly when sticks centered
9) Other items:
a) faster EKF startup
b) Camera control messages sent via MAVLink to smart cameras. Allow control of camera zoom for upcoming IntelEdison/Sony QX1 camera control board
c) Lost Copter Alarm can be triggered by holding throttle down, roll right, pitch back
10) Bug fixes:
a) Home position set to latest arm position (it was being set to previous disarm location or first GPS lock position)
b) bug fix to mission Jump to command zero

a) Add desired descent rate check to reduce chance of false-positive on landing check
b) improved MPU6k health monitoring and re-configuration in case of in-flight failure
c) Rally point distance check reduced to 300m (reduces chance of RTL to far away forgotten Rally point)
d) auto-disarm if vehicle is landed for 15seconds even in Auto, Guided, RTL, Circle

2) TradHeli landing check ignores overall throttle output
3) reduce AHRS bad messages by delaying 20sec after init to allow EKF to settle (Pixhawk only)

5) Safety Items:
a) Baro glitch check relaxed to 5m distance, 15m/s/s max acceleration
b) EKF/INav check relaxed to 80cm/s/s acceleration correct (default remains as 0.6 but this now means 80cm/s/s)
c) When GPS or Baro glitch clears, the inertial nav velocities are *not* reset reducing chance of sudden vehicle lean
d) Baro altitude calculation checked for divide-by-zero and infinity
6) Bug Fixes:
a) AltHold jump bug fixed (altitude target reset when landed)
b) Rally point bug fix so it does not climb excessively before flying to rally point
c) body-frame rate controller z-axis bug fix (fast rotation in z-axis would cause wobble in roll, pitch)
------------------------------------------------------------------
2014-08-01 01:56:09 -03:00
ArduCopter 3.2-rc4 01-Aug-2014

When EKF is not used inertial nav's accelerometer corrections are used as a substitute
b) Barometer glitch protection added. BAROGLTCH_DIST and BAROGLTCH_ACCEL parameters control sensitivity similar to GPSGLITCH protection

1) Hybrid mode - position hold mode but with direct response to pilot input during repositioning (JulienD, SandroT)
2) Spline waypoints (created by David Dewey, modified and integrated by Leonard, Randy)
3) Drift mode uses "throttle assist" for altitude control (Jason)
4) Extended Kalman Filter for potentially more reliable attitude and position control (Pixhawk only) (Paul Riseborough). Set AHRS_EKF_USE to 1 to enable or use Ch7/8 switch to enable/disable in flight.
5) Manual flight smoothness:
a) Smoother roll, pitch response using RC_FEEL_RP parameter (100 = crisp, 0 = extremely soft)
b) Adjustable max rotation rate (ATC_RATE_RP_MAX, ATC_RATE_Y_MAX) and acceleration (ATC_ACCEL_RP_MAX, ATC_ACCEL_Y_MAX)
6) Autopilot smoothness:
a) Vertical acceleration in AltHold, Loiter, Hybrid modes can be configured with PILOT_ACCEL_Z parameter (higher = faster acceleration)
b) Maximum roll and pitch angle acceleration in Loiter mode can be configured with WPNAV_LOIT_JERK (higher = more responsive but potentially jerky)
c) Yaw speed can be adjusted with ATC_SLEW_YAW parameter (higher = faster)
d) smoother takeoff with configurable acceleration using WPNAV_ACCEL_Z parameter
e) Twitches removed during guided mode or when entering Loiter or RTL from high speeds
7) Mission improvements:
a) mission will be resumed from last active command when pilot switches out and then back into Auto mode (prev behaviour can be restored by setting MIS_RESTART param to 1)
b) DO_SET_ROI persistent across waypoints. All-zero DO_SET_ROI command restores default yaw behaviour
c) do-jump fixed
d) conditional_distance fixed
e) conditional_delay fixed
f) do-change-speed command takes effect immediately during mission
g) vehicle faces directly at next waypoint (previously it could be about 10deg off)
h) loiter turns fix to ensure it will circle around lat/lon point specified in mission command (previously it could be off by CIRCLE_RADIUS)
8) Safety improvements:
a) After a fence breach, if the pilot re-takes control he/she will be given a minimum of 10 seconds and 20m to recover before the autopilot will invoke RTL or LAND
b) Parachute support including automatic deployment during mechanical failures
9) Other enhancements:
a) V-tail quad support
b) Dual GPS support (secondary GPS output is simply logged, not actually used yet)
c) Electro Permanent Magnet (aka Gripper) support
d) Servo pass through for channels 6 ~ 8 (set RC6_FUNCTION to 1)
e) Remove 80m limit on RTL's return altitude but never let it be above fence's max altitude
10) Other bug fixes:
a) Bug fix for LAND sometimes getting stuck at 10m
b) During missions, vehicle will maintain altitude even if WPNAV_SPEED is set above the vehicle's capabilities
c) when autopilot controls throttle (i.e. Loiter, Auto, etc) vehicle will reach speeds specified in PILOT_VELZ_MAX and WPNAV_SPEED_UP, WPNAV_SPEED_DN parameters
11) CLI removed from APM1/2 to save flash space, critical functions moved to MAVLink:
a) Individual motor tests (see MP's Initial Setup > Optional Hardware > Motor Test)
b) compassmot (see MP's Initial Setup > Optional Hardware > Compass/Motor Calib)
c) parameter reset to factory defautls (see MP's Config/Tuning > Full Parameter List > Reset to Default)

ArduCopter 2.8.1 22-Oct-2012
Improvements over 2.8:
- 430 bytes of RAM freed up to resolve APM1 level issue and reduce chance of memory corruption on both APM1 and APM2
Improvements over 2.7.3:
- Improved ACRO mode (Leonard Hall)
- Improved stability patch to reduce "climb-on-yaw" problem (Leonard, Rob Lefebvre, Randy)
- Rate controller targets moved to body frames (yaw control now works properly when copter is inverted) (Leonard/Randy)
- Less bouncy Stabilize yaw control (Leonard)
- OpticalFlow sensor support for APM2.5 (Randy)
- DMP works again by adding "#define DMP_ENABLED ENABLED" to APM_Config.h You can also log DMP vs DCM to the dataflash by adding "#define SECONDARY_DMP_ENABLED ENABLED" (Randy)
- Watch dog added to shutdown motors if main loop feezes for 2 seconds (Randy)
- Thrust curve added to linearize pwm->thrust. Removes deadzone found above 90% throttle in most ESC/motors (Randy)
- More timing improvements (main loop is now tied to MPU6000s interrupt) (Randy)
- GPS NMEA bug fix (Alexey Kozin)
- Logging improvements (log I terms, dump all settings at head of dataflash log) (Jason)
Bug Fixes / Parameter changes:
- fixed skipping of last waypoint (Jason)
- resolved twitching when no GPS attached (Tridge)
- fixed loss of altitude if alt hold is engaged before first GPS lock (Randy/Jason)
- moved Roll-Pitch I terms from Stabilize controllers to Rate controllers
- TILT_COMPENSATION param tuned for TradHeli (Rob)
Code Cleanup:
- HAL changes for platform portability (Pat Hickey)
- Removed INSTANT_PWM (Randy)
