Another great demo from the ETH team, proving that if you have a Vicon motion capture system you can do anything! From Robots.net
" The video is made by the Control of Distributed, Autonomous Systems lab of professor at the Swiss Federal Institute of Technology in Zurich (ETHZ), Raffaello D'Andrea. It is shot inside the Flying Machine Arena, a facility that provides a control environment for motion control research. The two quadcopters are based on the 'Hummingbird' quadrotor made by Ascending Technologies with new controls and custom made electronics fabricated by the institute. A vital component is a state of the art Vicon motion capture system that provides the localization data to the robots and makes extremely precise and dynamic control possible.
