07. Head tracking - PingguSoft/aTelloPilot GitHub Wiki
This feature uses magnetic sensor and gyro sensor on the deivce, so it is working when magenetic sensor is calibrated properly
1. turn on Tello in front of yourself (not facing yourself)
2. turn head tracking on without taking off
3. red arrow (device orientation) will be seen in heading indicator
4. rotate yourself holding the device and check the red arrow shows correct orientation
5. If not, rotate the device as 8 shape
6. check if it is working well
- Tello doesn't have GPS so it can't provide absolute coordinate
- And it doesn't have compass either so it can't provide absolute its heading
- So alignment is required when it is turned on and flight app is started
1. align the red arrow and drone orientation (plane) before take-off
2. take-off and spin yourself, drone will follow your heading
