Hello, I am interested in the flow deck. But I have several questions which I failed to figure it out by myself: 1. What's the resolution of the camera? I did not find this in the PMW33901 datasheet 2. Is the optical flow estimation hard-ware based? (I think so). (If it is code based)I plan to do so...

Hi, If it is similar to the master code (which is very likely), roll/pitch are in degree. Yaw is in degree per seconds and the thrust is from 0 to 65535 with 0 meaning 0% and 65535 meaning 100%. There is no range limit for the roll/pitch/yaw setpoints, there is of course a limit in the Crazyflie ph...

Hello,
I am doing my control research with CF. Based on Whoenig's code, I made some modification. But I don't know the exact 4 control inputs range. In Whoenig's code, he set pitch roll in (-15,15), yaw rate (-15,15), thrust (10000,60000). Does anyone can tell me what's the exact ranges?

Hi, have you looked at the Crazyswarm project (http://crazyswarm.readthedocs.io/en/latest/ and http://usc-actlab.github.io/publications/Preiss_ICRA2017.pdf)? I believe the Crazyswarm project implements forward velocity control. I read that paper. But it seems that the paper is trajectory following....

Hello,
I know many people control quadcopter's trajectory. I am wondering if it is possible to control the forward velocity of CF with feedback from vicon or optitrack. It seems the there is no related papers discuss quadcopter's velocity control.

It looks like the connection process hangged mid-way (the connection button shows "cancel" instead of "Disconnect"). Can you try to update both firmware and client to the latest version and changing the radio datarate to 2M? Hi, I have fixed it, it seems 4 markers are too heavy ...

Hi, How much margin do you have on the motor power? You can see that by looking at the individual motor thrust and see if any is close to 0 of 100%. By adding weight off-center you will start to reduce the power margin to control the Crazyflie attitude by pushing part of the motor closer to 100%. I...

Hello, For my experiment, I added some parts on the CF2. So every time I make it take off by just giving it thrust, it will take off and fly backward(toward the two blue LEDS). I think tuning the PID parameters should help. So I followed this post: https://forum.bitcraze.io/viewtopic.php?f=6&t=1...

Hi whoenig, I read the code again recently and still have several questions. For the hovering problem: 1. How could ROS know CF's position? I know it should be related to targetDrone, tf::StampedTransform transform; m_listener.lookupTransform(m_worldFrame, m_frame, ros::Time(0), transform); geometry...

Thank you!
