Read and Plot Navigation data Using MATLAB Support Package for Parrot Drones
This example shows how to use the MATLAB® Support Package for Parrot® drone to acquire and plot real-time navigation data of the Parrot drone
The MATLAB Support Package for Parrot Drones enables you to control and read the in flight navigation data of the drone.
In this example, you will learn to read navigation data of the Parrot drone such as the speed, orientation, and height using MATLAB commands.
To run this example you need the following:
A fully charged Parrot FPV drone
A computer with a WiFi connection
Task 1 — Hardware setup
Power on the Parrot FPV drone.
Connect your computer to the drone's Wifi network.
Task 2 — Create a parrot object
p = parrot();
Task 3 — Take-off the drone
Start the Parrot FPV drone flight from a level surface.
Execute the following command at the MATLAB command prompt the takeoff of the drone.
Task 3 — Initialize MATLAB
figure window properties
This task shows you how to initialize MATLAB to plot the navigation data.
animatedline to plot the variation in speed along the X, Y, and Z axes, separately.
Initialize the figure handle and create animated line instances hx, hy, and hz corresponding to speeds along the X, Y, and Z axes, respectively.
f = figure; hx = animatedline('Color', 'r', 'LineWidth', 2); hy = animatedline('Color', 'g', 'LineWidth', 2); hz = animatedline('Color', 'b', 'LineWidth', 2); title('DroneSpeed v/s Time'); xlabel('Time (in s)'); ylabel('Speed (in m/s)'); legend('XSpeed', 'YSpeed', 'ZSpeed');
Task 4 — Plot Navigation data during drone flight
Keep flying the drone along the desired path (forward diagonal path in this example) for 10 seconds and plot navigation data (speed) during this flight.
The default value of
move function is 0.5 seconds.
flightTime = 10; tObj = tic; while(p.BatteryLevel > 10 && toc(tObj) < flightTime) move(p, 'Pitch', deg2rad(-4), 'Roll', deg2rad(4)); speed = readSpeed(p); tStamp = toc(tObj); addpoints(hx, tStamp, speed(1)); addpoints(hy, tStamp, speed(2)); addpoints(hz, tStamp, speed(3)); drawnow; pause(0.1); end
Task 5 — Land the drone
Land the drone.
Task 6 — Clean up
When finished, clear the connection to the Parrot drone.
