addTakeoff
Description
addTakeoff(___,
sets
additional options specified by one or more name-value pair arguments in addition to all
input arguments from the previous syntax. For example,
Name=Value
)addTakeoff(mission,altitude,Frame="LocalNED")
adds a takeoff mission
item with the altitude specified in the local north-east-down (NED) reference
frame.
Examples
Create UAV Mission Manually
Create a UAV mission object with a home location at the origin of the local ENU coordinate frame and an initial speed of 5 meters per second.
m = uavMission(Frame="LocalENU",HomeLocation=[0 0 0],Speed=5)
m = uavMission with properties: HomeLocation: [0 0 0] InitialYaw: 0 Frame: "LocalENU" Speed: 5 NumMissionItems: 0
Add a takeoff mission item to the mission with an altitude of 25
meters, pitch of 15
degrees, and yaw of 0
degrees.
addTakeoff(m,20,Pitch=15,Yaw=0);
Add two waypoint mission items to the mission. Between the two waypoints, increase the speed of the UAV to 20
meters per second. After the second waypoint, reduce the speed of the UAV back to 5
meters per second.
addWaypoint(m,[10 0 30]); addChangeSpeed(m,20) addWaypoint(m,[20 0 40]); addChangeSpeed(m,5) addWaypoint(m,[30 0 50])
Add loiter and hover mission items to the mission, specifying for the UAV to loiter and hover around the second waypoint at a radius of 50
meters for 20
seconds each.
addLoiter(m,[40 0 60],10,20); addHover(m,[50 0 70],10,20);
Add a landing mission item to the mission to land the UAV.
addLand(m,[70 0 0],Yaw=0);
Show the mission item data table.

Remove the hover action at index 7
, and then add another waypoint at index 8
after the hover item moves to index 7
. Show the mission details table again to see the changes.

Input Arguments
mission
— UAV mission
uavMission
object
UAV mission, specified as a uavMission
object.
altitude
— Desired altitude
numeric scalar
Desired altitude, specified as a numeric scalar, in meters.
If the mission waypoint reference frame is Global
, this value
specifies an absolute altitude above the WGS84 reference ellipsoid. Otherwise, this
value specifies altitude relative to the home location of the mission.
Name-Value Arguments
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN
, where Name
is
the argument name and Value
is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Example: addTakeoff(mission,5,Pitch=15,Frame="LocalNED")
Pitch
— Desired pitch
NaN
(default) | nonnegative scalar
Desired pitch, specified as a nonnegative numeric scalar, in degrees.
Data Types: double
Yaw
— Desired yaw
NaN
(default) | numeric scalar
Desired yaw, specified as a numeric scalar, in degrees.
Frame
— Mission waypoint reference frame
mission.Frame
(default) | "Global"
| "GlobalRelativeAlt"
| "LocalENU"
| "LocalNED"
Mission waypoint reference frame, specified as one of these values:
"Global"
— Global reference frame"GlobalRelativeAlt"
— Global reference frame with an altitude relative to the home location specified bymission
"LocalENU"
— Local east-north-up (ENU) reference frame"LocalNED"
— Local north-east-down (NED) reference frame
If you do not specify the Frame argument, addTakeoff
uses the
reference frame of the uavMission
object
mission
.
Data Types: char
| string
Timestamp
— Timestamp
numeric scalar
Timestamp of this item, specified as a numeric scalar, in seconds.
If you do not specify the Timestamp
argument,
addTakeoff
determines the timestamp automatically based on the
reference speed of the uavMission
object.
InsertAtRow
— Item position in mission order
positive integer
Item position in the mission order, specified as an positive integer.
If you do not specify the Timestamp
argument or you specify a
value that is greater than the total number of items in the mission, the item is
inserted after the last item as the next index value.
