A fleet of drones connected to each other and to a ground station to overcome the current limits of battery power. Stem is an entrepreneurial venture created by e-Novia, the Enterprises Factory, and the Polytechnic University of Milan, and presented today at the CES in Las Vegas, the world’s greatest exhibition dedicated to technology and innovation. Stem stands for System of Tethered Multicopters, and the formation of Stem drones is able to fly for an unlimited time because the power supply is provided via a system of cables and winches which guarantee that the drones can move freely and ensure they can fly however long is necessary to complete their task.
“Stem embodies the industrial evolution of drones used for filming on construction sites or during events. Having more than one drone connected allows you not only to manoeuvre vertically over the ground station but also horizontally, away from the station”, commented Glauco Bigini of e-Novia, who is in charge of the project. “Stem aims to revolutionise the world of inspections and safety, work which is crucial, enabling monitoring and systematic checks which wouldn’t be possible with battery powered drones” added Ivo Boniolo, Chief Innovation Officer at e-Novia, who continued: “As well as in situ monitoring, Stem can also be used in the world of entertainment, enabling the filming of events from above in complete safety”. The model presented today at Las Vegas is the first prototype of the system of drone interconnections made up of a series of intelligent winches, and controlled by artificial intelligence algorithms, which integrate with the drone’s flight-control system and allow the drones to fly in formation.
