|
Improvements over 2.9-rc4: |
|

|
2) relax altitude requirement for take-off command to complete |
|
------------------------------------------------------------------ |
|

|
------------------------------------------------------------------ |
|
ArduCopter 2.9-rc3 11-Jan-2013 |

|
1) alt hold with sonar improvements - now on by default (Leonard/Randy) |
|
2) performance and memory useage improvements (Tridge/Randy) |

|
ArduCopter 2.9-rc2 31-Dec-2012 |
|
Improvements over 2.9-rc1: |
|
1) increased throttle rate gains from 1.0 to 6.0 |
|
2) APM1 fix so it works with inertial nav (5hz update rate of baro was beyond the tolerance set in the inav library) |
|
------------------------------------------------------------------ |
|
ArduCopter 2.9-rc1 23-Dec-2012 |
|
Improvements over 2.8.1: |
|
1) altitude hold improvements: |
|
a)inertial navigation for vertical axis [Randy/Jonathan/Leonard/Jason] |
|
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] |
|

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) |
|
