Wearable Universal Long-Range Hand-Gestured UAV Radio Control

Hand gesture control represents an alternative means of human-computer interaction. The focus of this research lies in an interactive medium, which takes the form of a hand controller specifically engineered to steer an unmanned aerial vehicle. This controller boasts remote and versatile capabilities, enhancing the overall experience of UAV flight control. The controller utilizes an Arduino microcontroller, a BNO055 IMU sensor for orientation, and a potentiometer for throttle control. The program implements a finite automaton (FA) for state-based control and communicates with the ExpressLRS receiver using the CRSF protocol. The experimental findings from the developed radio control device demonstrated no significant delay. The latency of the device is only 40ms. The system exhibited responsiveness within a 216 m range despite encountering various obstacles and interference during the tests. It utilized ExpressLRS with a power consumption of 25 mW.
