3. Drone Parts¶
props are used to create roll, pitch and yaw. Note that there are 2 types of props, clockwise
CW and counter-clockwise
CCW. The CCW props have
notches while the CW props do not. On every Tello, you should have 2 CW and 2 CCW props, and they should be placed diagonal from each other. With the Tello laying down and the battery facing towards your body and the camera facing away, the top-left and bottom-right props should be CCW props, and the top-right and bottom-left props should be CW props.
The motors are responsible for moving the props.
3.3. Landing gears¶
Landing gears help the drone land safely.
The body holds the main control board and communicates signals.
3.5. Electronic speed controller¶
The electronic speed controllers,
ESCs, are responsible for modulating signals to the motors from the main control board.
There is a receiver that listens in for incoming signals.
The antenna captures remote signals.
The battery powers the drone. The specification of the Tello battery is as follows.
Lithium Ion (Battery Type)
4.35 V (Max Charge Voltage)
3.8 V (Nominal Voltage)
1100 mAh, 4.18 Wh (Rated Capacity)
The camera is used to capture images or videos.
Some drones may have additional sensors (light, GPS, ultrasound, etc.). The Tello does not have such additional sensors, apart from the camera.
