[Solved] CF Bolt - Unstable takeoff
Posted: Tue Sep 14, 2021 8:26 pm
I have been having takeoff issues with my crazyflie bolt drone. I've already made a post - viewtopic.php?f=5&t=5026&p=23020#p23020 to try and solve similar issues
The issue from before has only gotten worse - https://www.youtube.com/watch?v=FMuNeoyRv7k
The drone can no longer even takeoff. If you look at the video frame by frame, you can see two of the motors lag behind on startup (the right two) and then the back right motor catches up right before the crash.
It seems that the issue is that not all of the motors start at the same time. How can I fix this issue?
WHAT IVE DONE TO TRY AND FIX ISSUE:
1. Reflash ESC's with new parameters - Used "onewire" technique to lower the "Startup Power" and raise the "PPM Max Throttle"
2. Tune Position and Velocity PID - slightly tuned P value down
Any input helps. It is most likely a hardware issue because the drone has taken off very well in the past.
