Peter Barker cd6e5b48a1 AC_Avoid: move check for zero-desired-velocity into adjust_velocity_polygon 
This is the method which divides by the length of this vector; the
check belongs in here.

Randy Mackay b7f3140441 AC_Avoid: stop includes margin for intersection calc 
the simpler stop feature (as opposed to slide) was not including the margin when looking for intersections with the boundary meaning it could slow too late

Andrew Tridgell d5c55e0dfe AC_Avoidance: removed create() method for objects 
See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach

Thanks to assistance from Lucas, Peter and Francisco

Dr.-Ing. Amilcar Do Carmo Lucas 823bee8a31 AC_Avoidance: Use SI units conventions in parameter units 
Follow the rules from:

and
http://physics.nist.gov/cuu/Units/checklist.html
one further constrain is that only printable (7bit) ASCII characters are allowed

Randy Mackay 2133fd94ca AC_Avoidance: adjust_velocity_z uses inav get_hgt_ctrl_limit 
inertial navigation's get_hgt_ctrl_limit provides an altitude-above-ekf-origin limit while flying with optical flow
 2017-01-18 09:35:47 +09:00
Randy Mackay f73efd5249 AC_Avoidance: add adjust_velocity_z 
This allows reducing the climb rate to slow the vehicle's climb so it does not breach the altitude fence

Randy Mackay b114d3928e AC_Avoid: fix distance to lean angle logic 
Fixes from PR review including
(a) make some local variables const
(b) rename angle_max to veh_angle_max
(c) fix distance_to_lean_pct logic so distance of zero returns maximum lean angle

Randy Mackay f27cf8d388 AC_Avoidance: add adjust_velocity that accepts Vector3f for convenience 
We should actually modify this function to scale back the z axis in order to avoid breaching the vertical fence.  Currently breaching the vertical fence is handled within the position controller which is inconsistent.

Randy Mackay a427768087 AC_Avoidance: reduce maximum acceleration to 1m/s/s
