Re: Fly two crazyflies with the motion capture
For new projects and especially if you want to fly multiple Crazyflies using ROS, it is recommended to use the Crazyswarm instead. If you encounter any issues, you might get better help by opening a discussion question on the Crazyswarm project.

Re: 'scf' is not defined
Error: Could you share the full error message that you are getting? Also, I assume you are using crazyflie-lib-python ? Multiple drones: You can ran multiple scripts separately, as long as you use one radio per Crazyflie. If you share a radio, you will need to find another way, as only one script ca...

Re: Crazyflie 2.1 can't fly with three attached decks
Could you share what the Console Tab in the cfclient shows (reboot your Crazyflie, then connect to it; user guide)?

Re: Help controlling Crazyflie using Web Bluetooth API
Very cool project! I wonder if you run into the thrust lock issue. Basically, you'll need to send at least one packet with thrust 0 first, to unlock the motors. This was done to avoid cases where one connects to the Crazyflie with a wrong joystick configuration (where motors would start spinning on ...

Re: Flying Multiple Crazyfiles
You can use the ROS Python API for subscribers (see http://wiki.ros.org/ROS/Tutorials/WritingPublisherSubscriber%28python%29 for a tutorial). Essentially, you would set-up a subscriber to listen on the "cf<id>/pose" topic. Then, every time you receive new data, a function will be called wi...

Re: Positioning system
Hi, * LPS: +/- 10cm; high jitter; Jitter can be reduced if you also add the flow deck (not yet quantified how accurate that combination becomes) * Lighthouse: +/- 2cm; very low jitter; (roughly, we are still in the process of measuring this) * Motion Capture: sub-millimeter; lowest jitter LPS and Li...

Re: Problems Kalman filter computation copy
Personally, I do a lot of development in different stages: 1. Conceptual design: First develop the method and a prototype in a high-level language that allows you to iterate quickly (e.g., Python or Matlab). You can ignore limitations such as real-time performance, memory limitations, etc. at this s...
