Re: Collision avoidance with LPS and multiranger deck

Hi,

is it possible to implement collision avoidance using multiranger deck with crazyswarm as well?

i cant find any tutorials or examples related to this.

Collision avoidance with LPS and multiranger deck

Hi,

Just wondering is it possible to use both LPS with UWB and multiranger deck at the same time,
such that the crazyflie will avoid obstacles when travelling from point A to B using LPS.

Is there any obstacle avoidance examples to try?

Thanks!!

Re: Crazyflie Bolt unable to hold altitude above 1.5m

i tuned the values and it's working fine in TWR mode, able to fly stable at 5m, however when i switched mode to TDoA3 the same problem happen again, may i know why?

And is the possible for crazyflie fly above or outside the area enclosed by the beacon in TDoA3 mode?

Thank you!

Crazyflie fly off in swarm

Hi, I was trying to fly 2 crazyflies using loco positioning system in twr mode using the swarmsequence script in cflib. The script works fine flying 1 crazyflie but when flying 2, the crazyflies will just fly off until it crashes. Tried running the script on same/different channel and address, still...

Re: Crazyflie Bolt PID Tuning

1. loco positioning in TWR mode
2. Slow oscillation, There is no oscillation when it travel from Point A to Point B, only oscillates when coming to a stop at Point B
3. The propellers are balanced

Does rate PID affects the drone when using loco position system?

Thanks Tobias!

Crazyflie Bolt PID Tuning

Hi,

i am tuning the position and velocity PID for my crazyflie bolt, however no matter how i adjust the PID values i cant get rid of the oscillation when the drone reach the set point and stops.

Does this has something to do with the rate PID? can anyone enlighten me please. Thanks in advance

Re: PID Tuner script

Thanks kimberly, i managed to figure out where went wrong, it turns out that the crazyflie took off in the wrong orientation.
Tested this script with bolt and loco positioning system, works perfectly fine.

PID Tuner script

hi,

i tried using the PID tuning script in the cflib but every time the crazyflie will just fly to one direction after take off.
Anyone can help me figure out what happened here? Thank you.
P.S The Loco positioning systems are well calibrated.

Re: Crazyflie Bolt unable to hold altitude above 1.5m

Thanks Tobias, it works better now after increasing the value.

May i know what is the difference between expPointA and expPointB?
