Since R2022b

Syntax

removeItem(mission,idx)

Description

removeItem(mission,idx) removes items at specified indices idx.

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.

showdetails(m)

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.

removeItem(m,7);
addWaypoint(m,[65 0 70],InsertAtRow=8);
showdetails(m)

Visualize the mission.

show(m);

idx — Indices of items to remove

N-element vector of integers in the range [1, size(mission.NumMissionItems)]
