Flying Airborne Drones Endlessly at Full Potential

Stem

The use of automated or pilot-operated flying drones is constantly increasing in every industrial sector. Drones are augmenting humans in high risk tasks and they are providing ubiquitous and unprecedented airborne capabilities previously available only to expensive, large and complex aircrafts. The increasing demand for longer flight time and operational flexibility limits the use of traditional battery-operated drone systems in several operational scenarios.

The Product

Stem – System of Tethered Multicopters – is a Politecnico di Milano spin-off company manufacturing a multicopter modular system. It allows a formation of two or more drones, each one connected with a tether carryingpower and high- speed data to a set of one or more ground stations.

How Does It Work?

The ground station and the drones are equipped with an electronic winch  designed to manage the tether length and to ensure a proper connection between the formation nodes. The formation can have a flexible topology, allowing the flight even in the most harsh and demanding environments. An A.I. algorithm works inside the ground station connected with the drones flight control units and with the winches. The A.I. algorithm allows strict control over the flying formation geometry. At the same time, it also checks the wire tension and it avoids tangling or improper formation geometries. Each drone is equipped with its own security control system (obstacle detection, centimeter- precision 3D positioning) ensuring high safety operations in any application. Stem providing an infinite flight time, allows overcoming current battery-operated drones limitations.

Aims and Next-Steps

The team of Stem is working on the final prototyping stage. The core team includes highly skilled researchers and engineers with expertise in mechatronics, automation and tethered flight.
