Merging Crazyswarm functionality into the official Crazyflie firmware

We have seen a big interest in flying swarms of Crazyflies and there are many challenges in doing so. The USC ACT Lab has developed Crazyswarm, a collection of software and firmware that allows to fly big swarms of Crazyflie using a motion capture system. This project has been used by USC and other universities to fly the most impressive swarms of Crazyflie 2.0 to date.

We are very happy that we together with Wolfgang and James, the main developer of Crazyswarm, have started to merge the firmware part into the official Crazyflie firmware. Merging the code will have two great consequences: people will be able to use Crazyswarm with a Crazyflie 2.0 running the stock firmware and everybody else will be able to use functionalities that has been developed for Crazyswarm.

There is currently a couple of parts that are in the works. The state controller has been merged already. There is currently some discussion on Github on how to merge the high-level commander, a commander that would allow the Crazyflie to autonomously follow trajectories as well as other high level commands. Finally there will be some work required to adapt the Kalman filter to make it more suited to accepts measurements from a motion capture system. The Crazyflie was not developed as an autonomous platform from the beginning but it is becoming one in big part thanks to the great contributions from the community.

A great thanks to James and Wolfgang for their effort in merging CrazySwarm in the Crazyflie code-base!

Out of stock
Unfortunately we miscalculated how much China slows down during Chinese new year which has caused some products to become out of stock. One of them is the Crazyradio PA which is also causing some bundles to become out of stock as well. The good news is that the products are in transit to the warehouse and will hopefully be back in stock any day now. Until then you can use the “Item out of stock – notify me!” functionality to get notified as soon as the product is back in stock.
