Incorporate GPS with Position Estimation
After going through the forum, I found out that the position updates from external positioning systems should be sent to estimatorEnqueuePosition ( https://github.com/bitcraze/crazyflie-firmware/blob/8f0c34a96c85fe2bc911cf0e529251e60c68e387/src/modules/src/crtp_localization_service.c#L141 ) Further ...

Gyro fails when starting
I get the following error when connecting to the cfclient. Also this leads CF to crash everytime I try to fly. MPU6500: Self test gyro X [FAIL]. low: -14.0, high: 14.0, measured: 25.69 MPU6500: Self test gyro X [FAIL]. low: -14.0, high: 14.0, measured: -31.62 MPU6500: Self test gyro X [FAIL]. low: -...

Limit the moving velocity in world coordinate following
I'm trying to move the CF to certain positions in a constant velocity using the send_position_setpoint command. But I noticed that at the start CF accelerates to a higher speed and trying to reach the destination as soon as possible. Is there a way to set a maximum velocity limit so that I can maint...

Re: Tuning PID after adding new decks
The problem is that the error accumulates with the distance when there is no pose correction. Currently I'm working on several methods for pose correction. The hardest part is to correct the pose using a limited number of ToF sensors. I will update the thread about the progress. Apart from that have...

Re: Tuning PID after adding new decks
There is no proper method to identify the out of range readings in VL53L1X. When an obstacle is not within the range, sensor gives random values. That's the reason to mark the cells as occupied at unnecessary places. Are you plotting the points with respect to the height to make a 3D plot? The bigge...

Tuning PID after adding new decks
https://forum.bitcraze.io/download/file.php?id=1059&mode=view I have made following upgrades in CF2. 1) A custom built deck is mounted at the top. 2) 500mAh battery is added. Weight - 12g, length - 45mm Apart from these a flow deck is attached and the overall flying weight is 42g. Now the CF se...

Variance of Kalman Filter
Hi, I tried logging the variance of Position x and y (varX and varY) using the python client. I'm trying to sample particles for a particle filter using these variances. But varX and varY stuck at 100 all the time. It doesn't converge to a lower value. Currently I'm using only the flow deck. Is any ...

This is the deck I made using 13 ToF sensors.

Re: Problem in logging z ranger data
I'm using my own python script. For now let's say I want to use the basiclogSync file to log the zranger data.
Currently I'm using latest firmware and it has the same problem.
