Connect to a Ryze Tello drone.

droneObj = ryze()
droneObj = 
          ryze tello with properties:

                    Name: "Tello"
                      ID: "TELLO-D2B07B"
                   State: "landed"
            BatteryLevel: 50%
        AvailableCameras: ["FPV"]

Use takeoff to initiate takeoff of the drone.


While the Ryze Tello is in flight, read the speed of the drone.

[speed,time] = readSpeed(droneObj)
speed = 
        0.8600  -0.0240  0.0015 
 time =

Input Arguments

collapse all

Ryze drone connection object, specified as a droneObj.

Output Arguments

collapse all

The current speed of the drone in m/s along the x-, y-, and z- directions with respect to the inertial NED frame. The NED frame is calculated at drone startup.

The time at which the speed data is received by MATLAB®, specified as a datetime.
