Crazyswarm

Description

The Crazyswarm is a swarm of miniature quadcopters (Crazyflie 2.0) that can fly together in close proximity. Our approach has the goal to make research in multi-robot systems safer, cheaper, and easier to reproduce. The Crazyswarm has the following features (amongst others):

  • Safe operation near humans
  • Small footprint allows to fly many vehicles in small lab spaces
  • Good crash resistance because of low inertia
  • Fully open-source
  • Off-the-shelf hardware
The system currently requires a motion capture system (e.g. VICON, OptiTrack, or PhaseSpace).

More information, including tutorials on how to setup the Crazyswarm, can be found on its webpage. A video demonstrating the swarms' capabilities is shown below.

We used the Crazyswarm to experimentally validate our trajectory planning approach for large quadrotor teams (see related publications below). In the future, we are looking at other applications, including distributed algorithms.
