Andrew Tridgell cbecb3eff9 sitl: we don't need mavlink in copter sim 2012-04-24 22:24:58 +10:00
Andrew Tridgell dd3218c913 pysim: ensure Vector3() uses floats 2012-03-29 12:39:53 +11:00
Andrew Tridgell 0b94b2e470 pysim: implement partial 3D acceleration support 
The simulator flies very badly when using the full acceleration
code. I don't yet know if this is a bug in the simulation or a problem
with AHRS not handling acceleration for multicopters.

For now set the acceleration to be half a 'pure gravity' acceleration
and half from the full 3D calculation.

Andrew Tridgell c020030620 pysim: added experimental acceleration support 2012-03-23 16:48:52 +11:00
Andrew Tridgell ccfac19cef pysim: update the multicopter simulator with correct acceleration 
this re-works the multicopter simulator in terms of rotation matrices,
and adds full acceleration support, which means it will include linear
acceleration affects and centripetal acceleration
 2012-03-22 23:00:45 +11:00

this is a python library for rotation matrices, following the
conventions in AP_Math
 2012-03-22 23:00:45 +11:00
Andrew Tridgell 5652ccd3c6 autotest: fixed the calculation of the acceleration due to gravity

Andrew Tridgell f4d7e108fa pysim: generalise the quadcopter code for multicopters 
this allows for arbitrary multicopter motor arrangements
 2012-01-04 19:13:15 +11:00
Jason Short 22172820a8 Made wind not reverse itself to be more natural 2011-12-29 23:02:02 -08:00
Andrew Tridgell 9f089f3b0e added a copy of fdpexpect 2011-12-23 12:20:58 +11:00
Andrew Tridgell e88a8e2519 more errno fixes for MacOS 2011-12-23 12:07:32 +11:00
Andrew Tridgell aaa0214ded autotest: fgrate option has been removed from mavproxy 2011-12-13 21:34:53 +11:00

Andrew Tridgell 5a2827e64b autotest: changed default sim_quad rate to 400Hz (matches autotest 
script)
 2011-12-13 13:44:53 +11:00
Andrew Tridgell f5a54f3da8 autotest: use 'enter 3 times' method to get into CLI 
this doesn't depend on build options
 2011-12-13 10:36:52 +11:00
Andrew Tridgell 0e75b3b140 autotest: added a test script for wind generation 
this makes it easier to experiment
 2011-12-13 10:36:52 +11:00
Andrew Tridgell 9ef929e88e autotest: added --wind option to sim_quad 
this is in the form of speed,direction,turbulance

Andrew Tridgell 6121942d42 pysim: fixed the accelerometer calculation in the quad simulator 
this was causing severe drift in the attitude calculation
 2011-12-12 21:57:09 +11:00
Andrew Tridgell 880f551efc autotest: fixed body/earth frames in sim_quad physics model 
Jason, can you have a look at this?
 2011-12-05 17:45:23 +11:00
Andrew Tridgell 9b3ce4a96a autotest: estimate the cost of sleeping for more accurate frame rate 
this gets us quite close to 1kHz simulation
 2011-12-03 07:38:51 +11:00
Andrew Tridgell 1192e2f11c autotest: run the quad simulation at a much higher rate 
it now defaults to 1kHz
 2011-12-03 07:24:58 +11:00
Andrew Tridgell 9dd2021ec8 autotest: support all 11 PWM output channels 
this will allow for more complex aircraft
 2011-12-02 22:45:48 +11:00
Andrew Tridgell a0baf71322 autotest: switch to big-endian metric packets internally 
now that all the sim code is internal to the APM git repo, we can
choose saner packet formats
 2011-12-02 22:12:58 +11:00
