Re: [SOLVED] Crazyflie 2.0 restarts after sending external position packet

Hi, Great that you got it to work! That would have been my suggestion. This should be documented, I am thinking of creating an autonomous flight page on the wiki. Would you have found the information there if it was posted on the wiki? I think it would defiantly help out. It took a bit to start con...

Hi,

thanks for sharing, this looks awesome!

Do you know if there is any plan of sharing the code as well so that others can reproduce your work?
You can find all the source code for this project, including the trajectory generation, on my github,

Crazyflie 2.0 playing ball-in-a-cup

As part of a class project, me and a team put together the sickest demo we could think of to demonstrate our controls integration skills.. a crazyflie 2.0 quadcopter playing the well known game ball-in-a-cup. https://lawrencepapincak.wordpress.com/2017/12/18/quadcopter-ball-in-cup/ This was complete...

Re: Optitrack and Crazyflie sloppy takeoff

What are you using to takeoff with? I had similar issues when just commanding a gradually increasing thrust. These issues disapeared when I started sending a hover setpoint (vx, vy, yawrate, zDistance). This was also while making the on board estimator default to the kalman filter based estimator. C...

Re: Optitrack with Crazyflie.

I've had great success with the ROS optitrack package from CRI group https://github.com/crigroup/optitrack I was streaming data over wifi and was able to achieve some pretty cool stuff. See my post about a ball-in-a-cup playing quadcopter I made using the optitrack for position feedback here. https:...

Re: Crazyflie 2.0 restarts after sending external position packet

I solved this issue by forcing the crazyflie to use the onboard kalman filter for state estimation and performing a reset of the estimator upon first connection to the quad. in src/modules/src/system.c 158 estimator = kalmanEstimator; and in my python script right after creating an new an instance C...

[SOLVED] Crazyflie 2.0 restarts after sending external position packet

I am attempting to send the crazyflie external position updates from a motion capture system. Everytime I send the external position packet via the crazyflie ROS package implementation, the copter restarts (motors beep, lights flash, etc.) and then sits idle flashing the M1 LED red at ~5 rapid flash...
