Annular Wing Quadrocopter from Santos Labs

Insitu’s new South American partner Santos Labs unveiled its multirotor  at LAAD 2013. A fish eyed 360 degree camera is fitted to the 1.5kg  quadrocopter. It uses an annular wing to provide lift and prop guard. Named Orbis the platform is waterproof and is intended to meet a Brazilian Navy requirement. The flight video shows a sprightly performance, for just how many minutes we wonder.

If you want to have a crack at building your own the Quadshot platform might be a good starting point http://transition-robotics.com/
