This is a video taken two years ago, recording the process from the start to the take-off of a FPV multi-copter. This is not a formal “how-to” video, but the effect of time-lapse shooting is interesting.
但話說回來,Navio+還是很新,他們把APM code port到Linux還是實驗性。他們的網站也這樣說:Important! Keep in mind that the code for Navio is in the experimental state. Use it with caution! 我也不打算把它用作實際飛行,最好可以在室內實驗,試試自己的程式。因此,以Lumenier Danaus做機架就可以保護縲旋槳和室內的人了。
Navio+ at Lumenier Danaus, 雖然Navio+在250機架有點大,但整體很簡約,未計電池重量約430g。
今天在FPV時,QAV250突然失控墜落,由於正在FPV,我看不見它確切的墜落位置,只知道它在前方3至400米處,位處山脊,有些草和矮小植物,不好找。我想起這條片(Finding lost RC planes using telemetry),不過我沒有他所裝的telemetry,只有搖控(FS-TH9X),我嘗試把天線指向不同的方位,果然在某些方向它會發出beep, beep聲,就以此為跟蹤器,去到比較接近時便很難試出方位有beep聲,便改為嘗試arm隻機,果然聽到arm fail的響聲,依著這個響聲便在草叢中找到它了。
NOTE: Do not connect any servos to the direct PWM outputs of your receiver. The RCIN port on the Pixhawk is designed for low power devices only, and a servo may draw a lot of current when moving rapidly. If you connect a servo directly onto your receiver while the receiver is powered from the RCIN port of your Pixhawk you may damage your Pixhawk.
