Guest post by Dominik Grzelak, Dresden University of Technology, Germany This blog post accompanies a research article published in the XR Salento 2025 proceedings (Springer LNCS). Setting up a mobile indoor positioning system with the Crazyflie platform—specifically using the Loco Positioning System (LPS)—typically involves walking through a large room with a laser measure, sticky notes,… Read More| Bitcraze
At the beginning of the year, we released the Crazyflie 2.1 Brushless charging dock. This project was very much an experiment for us since this is the first product we are mainly manufacturing and assembling by ourselves in Sweden. We though we would write a little bit about the reason we made it that way and how it is going.| Bitcraze
UAV Recharging for Remote Applications Unmanned aerial vehicles (UAV) are invaluable to challenging remote applications, including coastal monitoring, surveillance for safe passage in icy waterways, and search-and-rescue missions. However, after deployment in a remote setting, the functional life of the multirotor is ultimately limited by its battery life. The research we continue to investigate is the… Read More| Bitcraze
Debugging the Crazyflie using the debug-adapter kit gives you direct access to the STM32 with a hardware debugger. It makes it possible to pause execution, step through code, and inspect what’s happening in real time.| Bitcraze

Today’s blogpost comes from Joseph La Delfa, who is currently doing his Industrial Post-Doc with Bitcraze. The Qi deck and the Brushless charging dock allow you to start charging a Crazyflie quickly, without having to fiddle with a plug or a battery change. But when you need to charge 10 or more Crazyflies 2.x and… Read More| Bitcraze
At Bitcraze we like making decks! When we released the Crazyflie 2.0 we were really excited about the new deck connector we put on the platform. Using this, it was suddenly possible to expand the platform, adding new, more complex functionalities years after the initial release. It’s something that we really like about the Crazyflie.… Read More| Bitcraze
You might already be familiar with the Crazyflie’s presence in numerous publications across various research fields. However, in this blog post, we’ll return to the basics and showcase some robotics concepts that can be taught using our platform.| Bitcraze
Lately, at home and at work during my Fun Fridays, I have been trying to learn more about 3D CAD and more precisely about FreeCAD, mostly in the context of (ab)using our 3D printers :). Inspired by a couple of Crazyradio cases that have already been published, I started working on a Crazyradio 2.0 case… Read More| Bitcraze
With the Swedish summer upon us, things are more calm at Bitcraze. The summer is usually a time for us to look a bit more at fixing infrastructure and other things that we do not have time to work on the rest of the year. One of the things I have been looking at improving lately is the state of our Python projects.| Bitcraze
Swarm robotics has undergone rapid evolution and is now used in real-world applications. At the center of this exciting journey is the Crazyflie. Although small, its capabilities make it ideal for swarming applications in research, education, and prototyping.| www.bitcraze.io

A couple of weeks ago, we were at ICRA 2025 in Atlanta. This year’s ICRA drew over 7,000 attendees, making it the biggest edition yet. We had a booth at the exhibition where we showed our decentralized swarm demo. The setup included a mix of Crazyflie 2.1+ units with Qi charging decks and Crazyflie 2.1 Brushless platforms with our new charging dock. The entire swarm operated onboard, with two Lighthouse base stations for positioning. More details about the setup can be found in the recent s...| Bitcraze
Drones can perform a wide range of interesting tasks, from crop inspection to search-and-rescue. However, to make drones practically attractive they should be safe and cheap. Drones can be made safer by reducing their size and weight. This causes less damage in a collision with people or the environment. Additionally, being cheap means that the drones can take more risk – as it is less expensive to lose one – or that they can be deployed in larger numbers.| www.bitcraze.io
The lighthouse positioning system is an optically-based positioning system that allows an object to locate itself with high precision indoors. The system allows to get a precision of tracking approaching what can be achieved with a Motion Capture system, but for a much lower cost and with the advantage that the position is acquired onboard the tracked device rather than in the infrastructure.| www.bitcraze.io
It’s been 2 weeks ago that we went to ROSCon ’24 in Odense Denmark as exhibitor and silver sponsor! Since it was a 2-hour train ride for us, it made much sense for us to attend this as a company and we are very happy we did. In this blog post we are sharing our experiences of the event.| www.bitcraze.io
We will be going to ROSCon 2024, Odense Denmark on the October 22th and 23rd! We will be located at booth 21.| www.bitcraze.io
IROS in Kyoto is over and all Bitcrazers are finally back in Sweden again. We had a really good time in Japan and enjoyed all the interesting discussions we had with all of you, thanks!| Bitcraze
You might remember that at the beginning of this summer, we were invited to do a skill-learning session with the Crazyflie at the Robotics Developer Day 2024 (see this blog post) organized by The Construct. We showed the Crazyflie flying with the multi-ranger deck, capable of mapping the room in both simulation and the real world. Moreover, we demonstrated this with both manual control and autonomous wall-following. Since then, we wanted to make some improvements to the simulation. We now pre...| Bitcraze
Ever since we started going to fairs to show off the Crazyflies, we’ve been trying to push the boundaries for the demos. Often we’ve used the fairs as an opportunity to either develop new functionality or try out new ideas. Something we’ve always been interested in, especially for fairs, is autonomous flights. It’s hard to talk to people about the Crazyflie while trying to fly it at the same time. Back in 2015 we were using the Kinect for piloting the Crazyflie at the Bay Area Maker F...| www.bitcraze.io
Welcome to the “The Beginner’s Guide to Drones” for programmers curious about exploring the world of unmanned aerial vehicles (UAVs). If you’re a coder from another field, this guide will walk you through the basics of drones, their components, and how to start programming them. Let’s dive in and see how your coding skills can take flight!| www.bitcraze.io

We are excited to announce that we are working on several new link performance metrics for the Crazyflie that will simplify the troubleshooting of communication issues. Until now, users have had access to very limited information about communication links, relying primarily on a “link quality” statistic based on packet retries (when we have to re-send data) and an RSSI channel scan. Our nightly tests have been limited to basic bandwidth and latency testing. With this update, we aim to exp...| www.bitcraze.io
