Re: My off-board position control
For the linear-quadratic regulator I need to solve the algebraic riccati equation. In the solver I have to invert matrices, calculate determinants and solve linear equations (that's why I also use the Eigen library). To be honest I didn't even try to implement those things on the crazyflie. In the f...

Re: My off-board position control
Hi and thanks :) My client is based on the c-client by Jan Winkler: https://github.com/fairlight1337/libcflie My first tries to implement the off-board control also failed. I was using your logging system (logging system on the crazyflie-firmware unchanged). But I'm not quite sure why it didn't work...

My off-board position control
I create a new topic since it's off-topic in the other thread https://forum.bitcraze.io/viewtopic.php?f=12&p=10650&sid=920b59f8fed854aedc2bbe350140be1e#p10650 Here's a demonstration of the off-board position control I implemented. See the description for more informations. The attitude contr...

Re: Neural network for crazyflie 2.0
Yes it does. I also realised a position control with two LQ-regulators. The outer regulator calculates the desired roll, pitch and thrust. The inner one the necessary motorratios. Using a stereo camera I determine the position of the crazyflie. As soon as I upload a video I can post a link to the vi...

Re: Neural network for crazyflie 2.0
If you want to control fast things like the Crazyflie orientation I guess the only way it to program your neural network in the firmware itself. I've managed to calculate the motorratios on my pc and send them then to the crazyflie (1.0 version). But I couldn't use your logging routine. Instead eve...

crazyflie-bootloader vs crazyflie-lib-python bootloader
Hi,
I am not sure what these bootloaders do. What is the difference?

bootloader in https://github.com/bitcraze/crazyflie-l ... ster/cflib

Re: Thrust Units
The battery compensation for the CF 2.0 works for my CF 1.0 too. Now my regulator is able to hold the cf at the same altitude even with low battery, although it's too much thrust (for my model) now. I set the target point at an altitude of 0.5m but my regulator hold the cf at about 0.8m. So I think ...

Re: Thrust Units
Nice to know. That's exaclty what I was looking for. I have a CF 1.0 and will try this battery compensation with the CF 2.0 parameters. Do you know if there are any thrust vs volt analysis for the CF 1.0 too?
