Crazyswarm: A large nano-quadcopter swarm

An updated version is available here: • Crazyswarm: a large na...
--------------------------------------------------------
Crazyswarm is a swarm of 49 Crazyflie 2.0 nano-quadcopters operating in a new experimental robotics building at USC.
We localize the quadcopters with a Vicon motion-capture system and a custom object tracker that supports identical marker arrangements. Three shared radios broadcast position updates at 100Hz and send high-level trajectory commands to each vehicle. Vicon-IMU sensor fusion, trajectory evaluation, and position control are all performed onboard at 500Hz.
The rotating pyramid demo is built from ellipse commands. The USC letters demo is built from point-to-point commands with each vehicle planning fifth-order polynomial trajectories onboard. A Python scripting layer controls the overall sequence of events.
A forthcoming publication from our group will describe the components of this system, the platform constraints, tradeoffs, and the associated design decisions in detail.

You guys should start coming up with ideas for visual FX for music festivals with these. Also find a way to carry a projection screen / light fabric and synchronize the movement of them with a projector. I'd support your kickstarter ;)

seriously do the YMCA dance formation, like they form the Y then the M then the C then the A

[@bfz2563]

do you use crazyflie pa? 3 crazyflie pas control 49 aircraft? amazing!

[@LukaNyan]

wow!

[@phadadev2307]

How many cameras need to be used at least in this control that still has good performance?

[@hobbyrcbd]

Will you please tell me What type of positioning sensors used here ? looks like little speaker

[@wakewind4129]

neat

[@jimistixxdrums]

Needs sound

That would scare people. They would start to associate this project with scary military stuff. I don’t know why, but they do.
