This is a short demonstration of a simple delivery system, based on Volta+4Gmetry. Operator (who is virtually anywhere in the world) inserts the delivery point in Volta console (http://diydrones.com/group/volta). Route is automatically generated on the server, and written down to the drone via secure VPN over 4G (http://4gmetry.voltarobots.com/). The server arms the drone, starts the mission and monitors the progress in real-time (adjusting the route, if necessary). Volta server can manage several drones simultaneously. Feedbacks are highly appreciated!
