Flying robot with flight angle control based on solar cells

Flying robot with flight angle control based on solar cells

This technology is a system that maximizes the power generation efficiency of solar cells mounted on the top of a flying robot. It adjusts the flight attitude in real-time to remain perpendicular to sunlight by controlling the rotor drive angle and wing angle based on data from solar incidence sensors and wind direction/speed sensors.

The limited capacity of batteries built into flying robots makes long-term missions difficult. Even when solar charging is adopted, the power generation efficiency of the solar cells decreases depending on the flight attitude, and the flight path can become unstable.

This technology utilizes independent vertical swing control of the left and right wings and rotors that can rotate independently of the wings. It features a flight angle control algorithm and structure that maintains the flight path using wind direction and speed data while adjusting the flight attitude to keep the solar incidence angle perpendicular to the solar cell surface. Applicable to unmanned exploration, surveillance, and environmental monitoring, it improves service time and energy security, maximizes generation efficiency, and optimizes solar energy efficiency and propulsion routes for autonomous flight control.
