|
|
Copter 3.3-rc4 17-May-2015
|
|
Changes from 3.3-rc3
|
|
1) AutoTune:
|
|
a) save roll, pitch, yaw rate acceleration limits along with gains
|
|
b) more conservative gains
|
|
2) Roll, pitch rate control feed-forward now on by default (set ATC_RATE_FF_ENAB to "0" to disable)
|
|
3) Serial ports increased to maximum of 4 (set SERIALX_PROTOCOL to 1)
|
|
4) MOT_THR_MIX_MIN param to control minimum throttle vs attitude during landing (higher = more attitude control but bumpier landing)
|
|
5) EKF fixes/improvements

a) prevent yaw errors during fast spins
|
|
b) bug fix preventing external selection of optical flow mode
|
|
6) Parachute:

------------------------------------------------------------------
|
|
Copter 3.3-rc2/rc3 02-May-2015
|
|
Changes from 3.3-rc1
|
|
1) AutoTune reliability fixes (improved filtering to reduce noise interference)
|
|
2) Optical flow improvements:
|
|
a) Range Finder pre-arm check - lift vehicle between 50cm ~ 2m before arming. Can be disabled by setting ARMING_CHECK to "Skip Params/Sonar"
|
|
b) Vehicle altitude limited to range finder altitude when optical flow is enabled
|
|
3) AltHold & Take-off changes:
|
|
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
|
|
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.
|
|
5) Aux channel features:
|
|
a) Emergency Stop - stops all motors immediately and disarms in 5 seconds
|
|
b) Motor Interlock - opposite of Emergency Stop, must be on to allow motors to spin motors, must be off to arm
|
|
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
|
|

|
|
e) fence breach while vehicle is landed causes vehicle to disarm (previously did RTL)

|
|
a) Check flight mode even when arming from GCS (previously it was possible to arm in RTL mode if arming was initiated from GCS)

|
|
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)

|
|
b)accel based throttle controller [Leonard/Randy]
|
|
c)accelerometer calibration routine updated to use gauss-newton method [Randy/Tridge/Rolfe Schmidt]
|
|
d)parameters to control climb rate:
|
|
AUTO_VELZ_MIN, AUTO_VELZ_MAX - allows you to control the maximum climb and descent rates of the autopilot (in cm/s)
|
|
PILOT_VELZ_MAX - allows you to control the maximum climb/descent rate when in alt hold or loiter (in cm/s)
|
|
2) landing improvements [Leonard/Randy]
|
|
LAND_SPEED - allows you to set the landing speed in cm/s
|
|
3) camera related improvements:
|
|
a) AP_Relay enabled for APM2 and integrated with AP_Camera [Sandro Benigno]
|
|
b) camera trigger with channel 7 switch or DO_DIGICAM_CONTROL mission command [Randy]
|
|
c) allow yaw override by pilot or with CONDITIONAL_YAW command during missions [Randy]
|
|
YAW_OVR_BEHAVE - Controls when autopilot takes back normal control of yaw after pilot overrides (0=after next wp, 1=never)
|
|
4) trad heli improvements [Rob]
|
|
a) code tested and brought back into the fold (2.8.1 was never released for trad helis)
|
|
b) enabled rate controller (previously only used angle controllers)
|
|
c) fix to rotor speed controllers - now operates by switching off channel 8
|
|
d) allow wider collective pitch range in acro and alt hold modes vs stabilize mode
|
|
e) removed angle boost function because it created more problems than it solved
|
|
f) bug fix to allow collective pitch to use the entire range of servos
|
|
5) mediatek gps driver improvements [Craig]
|
|
a) added support for 1.9 firmware
|
|
b) bug fix to start-up routine so sbas can be enabled
|
|
6) failsafe improvements (both throttle and battery) [Randy/Craig/John Arne Birkeland]
|
|
a) RTL will not trigger if your throttle is zero - reduces risk of accidentally invoking RTL if you switch off your receiver before disarming
|
|
b) failsafe triggered in unlikely case of a PPM encoder failure
|
|
c) bug fix to resolve motors momentarily reducing to zero after failsafe is triggered
|
|
7) mpu6k filtering made configurable and default changed to 42hz for copters [Leonard/Tridge]
|
|
8) support ppm sum for transmitters with as few as 5 channels [Randy/John Arne Birkeland]
|
|
9) acro trainer - copter will return to be generally upright if you release the sticks in acro mode [Leonard]
|
|
ACRO_BAL_ROLL, ACRO_BAL_PITCH - controls rate at which roll returns to level
|
|
ACRO_TRAINER - 1 to enable the auto-bring-upright feature
|
|
10) other changes and bug fixes:
|
|
a) allow >45 degrees when in stabilize mode by adding lines like below to APM_Config (compile time option only) [Jason]
|
|
#define MAX_INPUT_ROLL_ANGLE 6000 // 60 degrees
|
|
#define MAX_INPUT_PITCH_ANGLE 6000 // 60 degrees
|
|
b) bug fix to stop RTL from ever climbing to an unreasonable height (i.e. >80m) [Jason]
|
|
c) event and state logging [Jason]
|
|
d) allow cli to be used over telemetry link [Tridge]
|
|
e) bug fix to allow compass accumulate to run when we have spare cpu cycles [Randy]
|
|
f) bug fix so do_set_servo command works [Randy]
|
|
g) bug fix to PID controller's so they don't calculate crazy D term on the first call [Tridge]
|
|
h) bug fix to initialise navigation parameter to resolve twitch when entering some navigation modes [Jason]
|
|
i) performance improvement to copter leds - use DigitalFastWrite and DigitalFastRead instead of native arduino functions [Randy]
|
|
j) removed unused stab_d from roll and pitch controller [Jason]
|
|
k) bug fix for guided mode not reaching target altitude if it reaches horizontal target first [Randy]
|
|
l) code clean-up, parameter documentation improvements [Randy/Jason/Rob/others]
