Skoltech scientists have created the DroneLight interface, which allows the user to control a small drone with a hand movement to create light images or letters. It can be used for remote communications, entertainment applications, and search and rescue operations.

Drones are already widely used in industrial and consumer applications. The creators of the devices are currently working on improving the human interaction with the “drone”. Previously, intuitive control of drones using existing technologies required special training and additional equipment. “Controlling the flight of a drone is challenging as it requires a joystick. Enough experience is required for the smooth movement of the “drone” or to draw a letter, “said co-author of the project, Professor Dmitry Teterukov.
Scientists have created a system that makes it easy to control a microcopter, which has an LED for creating light images. To do this, we used a small Crazyflie 2.0 quadcopter with dimensions of 92x92x29 mm, its weight is 27 g, it is equipped with reflectors and a panel of controllable RGB LEDs. The drone control system is a glove that has an inertial measurement unit and a base station equipped with a machine learning algorithm. It correlates the movements of the operator's hand with predetermined letters or images, and the “drone” directs light on them on command. To test the design, the researchers used five Latin letters (S, K, O, L and J) and trained the random forest classifier algorithm to combine the operator's hand movements and the microcopter's trajectory. The experts intend to continue improving the design.
