Playing with Crazyflie 2.1 choreography with Lighthouse positioning

We have recently moved to a new bigger office. With the summer arriving in Sweden, it was time to organize a small move-in after-work party with friends and family. For the occasion we wanted to play around with a small swarm of Crazyflies and the new Lighthouse positioning. Time being a sparse resource, we setup the ICRA2019 demo in the flight lab so that we would be able to fly during the party. We also started looking at our old swarm show that we ran with the LPS a year ago to see if we could run it with Lighthouse:

The show was a essentially a sequence of setpoints sent from a python script and controlling 9 Crazyflies 2.1 equipped with Lighthouse deck on the top and led-ring deck on the bottom synchronized on music. We setup the Crazyflie in the Lighthouse positioning system and converted the script to use the high-level-commander GOTO setpoints. We look forward at trying more advance control problems like trajectories to make more impressive synchronized flight choreography in the future but for now it already look quite good even with only GOTOs:
