The Massachusetts Institute of Technology (MIT) has developed an innovative technology that allows drones to navigate smoothly in dark interior spaces. This system, called Mifly, makes it possible for drones to autonomously move using smart radio frequency technology instead of expensive night vision cameras.

Sensitive interior navigation with radio frequencies

Mifly’s working principle is based on communication between special labels placed in indoor spaces and radar systems mounted on drones. The system, which uses high frequency radio waves called millimeter waves (MMWave), can determine the position of the drones with a sensitivity of 7 centimeters. This sensitivity offers an ideal solution for sensitive tasks such as package transport and inventory management, especially among warehouse shelves.

One of the most important features of the system is that the drone integrated with the unit of inertia measurement unit (IMU). Thanks to this integration, the direction and slope angles of the drone can be detected precisely. Mifly combines these data with radar signals and provides precise positioning throughout the degree of freedom. Moreover, the system can work effectively at distances up to 6 meters, even if not in the field of view of the label drone.

The radar system developed by the MIT team is specially designed to prevent parasites. The system, which can distinguish polarized horizontal and vertical signals and uses different modulation frequencies, offers reliable navigation even in complex interiors. Finally, this innovative technology will be presented at the IEEE International Computer Communication Conference, which will be held in May 2025 in London.
