|
* AP_mount -- library to control a 2 or 3 axis mount. *
|
|
* *
|
|
* Author: Joe Holdsworth; *
|
|
* Ritchie Wilson; *
|
|
* Amilcar Lucas; *
|
|
* Gregory Fletcher; *
|
|
* *
|
|
* Purpose: Move a 2 or 3 axis mount attached to vehicle, *
|
|
* Used for mount to track targets or stabilise *
|
|
* camera plus other modes. *
|
|
* *
|
|
* Usage: Use in main code to control mounts attached to *
|
|
* vehicle. *
|
|
* *
|
|
* Comments: All angles in degrees * 100, distances in meters*
|
|
* unless otherwise stated. *
