Python-based App layer

I'm looking for a way to move my python code (which is written using CFLib) to the firmware. I think the app layer is the option for me to implement it, but it's C code. Is it possible to use python code for app layer? If so, could you share a sample code?

Re: Implementation of Ready To Fly Mode

I implemented it using python library. Here is the code you can use: roll = 0 pitch = 0 yawrate = 0 print("let's go") thrust_mult = 1 thrust_step = 500 thrust = 20000 cf.commander.send_setpoint(0, 0, 0, 0) for r in range(10): cf.commander.send_setpoint(roll, pitch, yawrate, thrust) time.sl...

Cutting the CF PCB

In our design, we would like to cut the arm's section of crazyflie PCB to make it compatible with our frame (The cutting lines are shown with red line in the following image). Since I couldn't find the PCB of crazyflie 2.X, I have no idea about the circuit tracks' pattern on the crazyflie. Is there ...

Replacing the brushed motors with powerful motors

Due to the limited payload capability of CF, I'd like to replace the current brushed motors with more powerful ones. My question is what is the maximum current for each motor driver? I appreciate it if anyone here suggests more powerful brushed motors that I can use.
Thanks

LH Sample Frequency

According to the paper (https://arxiv.org/abs/2104.11523), the sampling frequency for LH2 has a huge standard deviation which is about 18. While the LH1's sample frequency is about 30 ± 2.4. My question is why we should select LH2 while the LH1 offers better sample frequency? Also, the paper doesn't...

Re: Crazyflie Not Landing on Specified Coordinates

Hi sbradley, I saw the video you shared. It is interesting to me how Lighthouse works in the environment with lots of towers that block the beams ray. How many base stations you sued and also which method (Beam Crossing or EKF) was utilized in your project? Did you try the landing without tall tower...

Lighthouse perfromance at high altitudes

In my application, the drone should fly up to 2m. I want to make sure that the performance of positioning and flight is the same at all altitudes from 0cm to 200cm. I appreciate it if you could share your experience working with the lighthouse in this case. FYI, the base station will be installed at...

Does Crossing Beam method work stable and accurate with only one base estation?

I'd like to use Lighthouse positioning system in my application where a human as a subject stands in the center of the testbed and a Crazyflie flies around him/her. It means if we use two base stations there are some spots without line of sight (LOS) to one of the stations. So it is necessary for th...
