Thanks to the people at GRASP Lab , part of the University of Pennsylvania, we have quadrotors that can do things like make figure eights. Amazing how the swarm of quadrotors can change formation patterns mid flight.
Alex Kushleyev, Daniel Mellinger and professor Vijay Kumar have developed the quadrotors.
Check out Daniel Mellinger’s page for more information on his quadrotor developments. Nice work guys. I wonder how they are sending commands to the quadrotors and how long then can stay in the air.
